The new metro station in St. Petersburg will be anti-vandal and in Zenit colors.
The station is in a hurry to turn in one day ahead of schedule, that is, on April 29. This is fundamentally important. For the match “Zenit” – CSKA Moscow Russian Championship, passengers to the “Stadium St. Petersburg” must travel through “Novokrestovskaya.” Actually, for this purpose the continuation of the Nevsko-Vasileostrovskaya line was built.
“Novokrestovskaya” will be in the colors of “Zenith”, Neva water or ice of the Gulf of Finland. To whom as a fantasy prompts. By the way, in the matter of facing, the pavilions under construction are on the front line.
Here they mount not granite blocks, as on all previous ones, but super-thin metal-ceramic panels. It would seem that at the station, which will take the first blows of the inflated fans, there must be something more simple. But builders believe in nanotechnology, says NTV correspondent Anton Zykov.
“Novokrestovskaya” is a station-paradox. It seems to be a closed type. But the passenger has descended to the platform, and the person opposite can be seen and the whole composition too. The fact is that they will not install walls here, but high-strength dark glass.
Exactly the same will be the door. While they are hidden in cardboard, do not get dust. Of course, everything is dictated, first of all, by security. But the metrostroducers themselves say that it will be aesthetically beautiful.
Despite the focus on the wind loading in the determination of glass thickness, damage surveys conducted following recent disasters have revealed that wind pressure does not cause glass breakage factor such as wind borne debris, excessive building motion and blast pressures have been documented as the cause of widespread glass breakage the designers of window glass at the affected project did not anticipate these factor. A major consequence of the glass breakage was a breach in the building envelope that resulted in damage to property and personal injury.
A substantial amount of glass breakage occurred in a relatively small area in downtown Houston Texas during Hurricane Alice. The density of broken window glass lites can be readily observed from the density of the plywood replacement panels. It is highest at a level near the elevation of the roof line of an adjacent building. The breakage density decreases with change in elevation from rooflines of adjacent building. This suggests strongly, if not conclusively, that the window glass broke as the result of wind-borne debris , such as roof gravel, carried by the wind from the adjacent building. Close-up photo of broken windows revel from the fracture origin and pattern that breakage was caused by impact rather than by the wind certainly wind was a factor in that it carried the debris but it was a factor in that it carried the debris but it was not the ultimate cause of breakage
Window glass broke during explosions results from uniform pressure loading of high magnitude and short duration. in explosions, wind has nothing to do with glass breakage. Glass breakage is also common in areas subjected to earthquakes Breakage occurred almost at the onset of shaking in a department store near Union Square in san francisco during the loam prieta earthquake of October 17, 1989. Again wind had nothing to do with the breakage other building affected by the earthquake show evidence of racking movements that could resulted in but fortunately did not glass breakage
Spontaneous glass breakage often occurs at project glazed with fully tempered glass Nickel sulfide contamination , a leading cause of spontaneous breakage of tempered glass, apparently cannot be eliminated completely by glass manufacture and this problem has caused sufficient concern that one manufacture has adopted a policy restricting the use of tempered glass for most architectural glazing application
All this case show that window glass breaks as the result of varying causes must of which have no relationship to wind loads Architect or engineers cannot possibly be expected to amount for all possible events that might break window they are designing . one of the designers main goals , though should be to product designs that minimize damage and injury in the event of window glass breakage
Laminators know it too well: laminating nipping is a critical phase of the glass laminating process because improperly set and inadequately controlled parameters will cause air-related and sometimes irreparable defects in the laminate.
As these only could get worse in the autoclave, it is important to have the right configuration of the nip roller line.
A key parameter is temperature – on the line and in the environment – as it affects the mechanical properties of PVB during the glass lamination process. The right temperature will uniformly soften the PVB surface and allow the air out under nip roller pressure.
If the temperature is too hot at the edges, the air will be trapped in and bubbles will form. We see it too often, when line control elements are triggered by underperforming parameters, corrective action comes too late and part of the production is doomed.
Ultimately, the robustness of laminates is directly dependent on temperature. Controlling it effectively is paramount to the production of quality products. Convection and infra-red radiation systems require a good understanding from the operator of the interaction between them to allow lamination at the right temperature.
Many of the issues that laminated glass producers face come from inadequate control of the production line. At EVERLAM, we have in-depth technical knowledge and expertise acquired over years of working with our customers to work out improvements, fix issues and find creative solutions.
We work with laminating line producers and laminators to provide technical assistance, tools and programs to enhance the productivity of your manufacturing operations. We also assist with training of the production and maintenance team.
Gone are the days when media facades were exclusive to the West. Over the past few years, this beautiful lighting concept has taken baby steps and is gradually gaining popularity in India.
The very concept is to make the building look outstanding and to impart an individual character to it after sunset. Especially, it is catching up fast in the retail hubs. Here light is used to highlight architectural details and create a drama.
Media facades fits in perfectly with our 24/7 lifestyle. The building looks equally attractive at day and night. Until recently, only wall washers and floodlights were used to light up a building at dark.
With media facades coming in vogue, the building comes alive at night with beautifully lit LEDs. Facade Integrated lighting mechanism is used to put together the media facade. The lighting can be customized and it is a powerful tool to interact with people.
Industry experts feel this lighting concept has a huge scope in India. It is a revolution in the architectural arena and a phenomenal jump from floodlight washers. According to them, this concept is relatively new in our country and has not yet been explored totally.
“In Tamil Nadu, only nineteen to twenty buildings have media facades. But it is catching up gradually. Cities like Delhi, Mumbai, Ahmedabad, Kolkata and Bangalore also has good scope”, says Mr. M. A. Chandrasekhar, Director of SE LED Technology.
According to Mr. Chandrasekhar, maintenance is not much of an issue too. With periodic supervision, media facades hardly give any trouble. “12 of my projects are remotely managed & controlled from the headquarters and a maintenance site visit once in three months is just enough”, adds Mr. Chandrasekhar.
This system is energy efficient as well. “Four hours of lighting cost for a spread facade area of 12000 sq. ft. with a 6.5 watts per sq. ft. design is about one thousand and two hundred rupees”, asserts Mr. Chandrasekhar.
Concealed door hinge carries aluminium door leaves with a weight of up to 140 kg.
Door manufacturers have been producing both reliable and durable connections between door leaves and frames with surface-mounted and butt hinges from the Roto Solid product range for many years. With the “Solid C 7.140” Roto now also offers a concealed door hinge for aluminium main doors.
The specialist for door technology develops individual solutions adapted to the aluminium profile for manufacturers who want to work with this door hinge that is visionary in terms of its aesthetics. The new door hinge is available in the colours silver and black.
Roto “Solid C” carries aluminium door leaves with a weight of up to 140 kg and an opening angle of up to 110°. The complete product name – Roto “Solid C 7.140” – gets to the heart of the new hinge’s essential features: “C” for concealed, “7” for the durability corresponding to Class 7 of DIN EN 1935 and “140” for the maximum leaf weight.
The concealed door hinge has proven its effortless durability even at 400,000 cycles. Its impressive functional life is therefore far beyond the value set by the standard. Thanks to the self-lubricating bush, the Roto Solid C moves any aluminium door without ever requiring maintenance.
The door hinge is suitable for burglar inhibiting door equipment in accordance with RC 2 and is corrosion-resistant according to DIN EN 1670 Class 5, thereby maximising the utility for the builder.
Door installation made easy
The new addition to the product range reveals its other strengths during door installation. The new FixClick function enables the leaf to be hinged quickly and securely and permanently holds the door in the support-bracket. Hinging and unhinging the leaf is made even easier by using the optional assembly aid kit.
It contains an air cushion, which facilitates the handling of heavy leaves and protects them from damage, and locking wedges, which aid installation. The wedges fix the hinge supports in position, so that they do not move during hinging.
Once the door leaf is hinged, the height is adjusted between –2 to +4 mm centrally and quickly only at the bottommost hinge. Thanks to the good accessibility of all hinges, the later adjustment of the height and gasket compression (±1.2 mm) as well as the lateral adjustment (±3 mm) are possible without any problems.
The assembly tool – also included in the assembly aid kit – can also be used to loosen the spring clip again, if the leaf needs to be unhinged again. The locking cap is also fitted conveniently with the tool after hinging. It is possible to order the components in the assembly aid kit individually.
The door hinge expert Roto also shows how to install and adjust the “Solid C” online, with a QR code that can be found on every door hinge. If installers or facility management employees scan this code with their smartphone, the Roto Solid C installation video opens. It gives detailed instructions on how to install and adjust the main door easily and quickly, and is always on hand.
SILVERSTAR DYNAMIC reacts automatically to light and heat conditions.
We spend up to 90 percent of our time inside buildings. So it’s all the more important to ensure this is high quality time. Evidence shows that lots of daylight and being able to look out of the building to the natural environment or urban surroundings make a significant contribution towards our sense of well-being.
But even the incorporation of large glass façades does not always bring about an improvement – quite the contrary: Effects such as annoying reflections, dazzling sunshine and overheating rooms can have a detrimental impact on people’s sense of well-being.
SILVERSTAR DYNAMIC from Glas Troesch removes any obstacles to the creation of a comfortable room climate with plenty of daylight and undisturbed views to the outside. Because the intelligent glass recognizes the differing weather situations and automatically adapts to the corresponding conditions. In this way, it ensures that there is both sufficient natural light as well as a permanent connection to the outside, promoting lasting comfort, health and efficiency.
We’re all familiar with the situation aren’t we: Outside the sun is shining whilst inside it’s got darker because solar protection elements are covering the glass façade.
To enable daylight to penetrate inside buildings, SILVERSTAR DYNAMIC has the intelligence to adapt to the differing conditions by darkening or brightening the glass panes – so the glass ensures rooms are kept well-lit throughout the day, maintaining continuous views to the outside.
The dynamic glass is controlled by an intelligent algorithm: Thanks to a system of ultra-sensitive sensors, the glass responds to sunlight; it is also supplied with current weather information and through individualised programming can be adapted to the specific architectural features of the façade and to the preferences of the users.
Three different factors make SILVERSTAR DYNAMIC the perfect partner for creating an optimum room climate. The automatic glare protection calculates the strength of the sunlight and alters the tint in such a way that those using the rooms are no longer blinded by the sun.
Secondly, SILVERSTAR DYNAMIC effectively prevents rooms from overheating – because the intelligent glass regulates the energy balance by controlling the total energy transmittance. Thirdly, coordinated with the other two parameters, the glass limits the maximum amount of daylight transmittance.
The three different parameters are kept in perfect balance, ensuring that a pleasant indoor climate is maintained at all times. The transitions from light to dark and vice versa are practically seamless, the change in tint is correspondingly smooth and goes almost unnoticed by the users.
Efficient use of energy
The demands for energy-efficient buildings today are higher than ever before. Thanks to SILVERSTAR DYNAMIC, solar protection elements are becoming superfluous. The intelligent glass lets in natural light and keeps heat out – so the dynamic glass effectively reduces the costs for cooling energy and electric lighting.
The results speak for themselves: SILVERSTAR DYNAMIC can reduce energy consumption by up to 20 percent, especially during peak times when energy costs are particularly high.
Simple control throughout: Every window, area or even the entire façade can be operated individually via wall switches, smart phones or tablets.
SILVERSTAR DYNAMIC increases well-being and performance: In trials, it was demonstrated that the productivity of users can be improved by 15 percent thanks to an increased amount of daylight and a permanent link to the outside.
Hospitals and their patients also derive clear benefits from SILVERSTAR DYNAMIC – patients whose rooms were supplied with sufficient daylight recovered on average eight percent more quickly than patients who were housed in darker rooms.

Obviously, glass fabricators want access to the latest thin glass laser cutting technologies to enable current and future product development within the marketplace.
Having access to laser-based processes is something most people within the industry agree, but it requires the technology itself to fit a facilities process flow, materials handling methodologies and ultimately add value to their products.
Freedom To Choose The Materials You Use. As it stands today, being competitive, is an absolute necessity; that doesn’t come from accessing technology that limits you to one material supplier.
The industry wants and deserves choice; this means they need to be able to access thin glass laser cutting technology without having to be limited to one thin glass materials manufacturer.
Ultimately working with a laser system group, as a technology partner, that works with its client to provide a complete solution for thin glass laser cutting and fabrication is optimum. Thin Glass
Opportunity: Converging Technologies. The outlook is exciting for laser cutting thin glass materials. New processes for laminating matched with complex geometries offer opportunities for innovation and product life-cycle extensions for existing products.
With the latest and greatest display techniques adapted to automotive applications, glass fabricators in the U.S. might be able to realize a surge in sales if they acquire flexible tooling for processing.
This flexibility also extends to being flexible in the thin glass materials they select; trading off name brands for high value-added niche markets and newer material sources for higher volume commercial and automotive applications.
The day of one source for precision thin glass material is in the past; more options are available at prices that will usher in a new age of innovation for those who embrace the technology. BOLD Products
Bensonwood chose a Solar Innovations® entryway to create a light, welcoming atmosphere. The building’s bright facade is inviting, promising a friendly customer experience.
When designing a new branch of the Savings Bank of Walpole, Bensonwood – a custom Design|Builder based in Walpole, NH – approached Solar Innovations®.
They were in need of a manufacturer for a glazed entryway and interior dividing walls for the bank. The client wanted a building that was both sustainable and customer focused. Natural light and an open, friendly atmosphere were top priorities.
The architect required fenestration that preserves indoor temperatures. Not only does this save money, but it also reduces the environmental toll of heating and cooling. Finally, the systems needed to be safe, secure, and accessible.
Creating a Welcoming Entrance
A building’s entryway is an important design factor, as it serves as a guest’s first impression. The strong, sturdy timber posts on the building’s exterior reinforce the dependability of the bank.
In contrast, Bensonwood chose a Solar Innovations® entryway to create a light, welcoming atmosphere. The building’s bright facade is inviting, promising a friendly customer experience.
Two sets of French doors create an entryway vestibule. Curtain walls on either side of the vestibule offer more daylight into the lobby. The exterior French door system uses insulated glazing and thermally broken aluminum frames, providing comfortable indoor temperatures even during extreme weather conditions.
Solar Innovations® constructed the curtain walls with the same framing as the French doors, creating a consistent appearance with matching sightlines. The use of an entry vestibule also helps prevent outdoor temperatures from affecting indoor comfort. Thermally efficient products and designs lower heating and cooling costs and reduce the toll on our environment.
The Clear Solution
At the front of the building is an ATM vestibule for bank members’ easy access. A single terrace door allows for egress from the ATM vestibule, providing a clear flow for quick, convenient transactions.
Separating the ATM vestibule from the main lobby is a Solar Innovations® Clear Glass Wall. This operable wall has no vertical frames between panels, offering a sleek, modern glass-to-glass look. Clear Glass Walls are often used in stadiums for a clear view of the game without interruptions.
However, their contemporary appearance and ability to feature custom configurations make them ideal for a wide range of applications. The top hung Slide & Stack panels can be moved along a single track to disappear from sight when stacked in a pocket inside the wall. Clear Glass Walls are also available in Sliding and Folding operations.
When closed, the 9’ tall Clear Glass Walls at the Savings Bank of Walpole offer great security. Keyed locks are located along the bottom rails. Bolts engage into dust proof strikes within the flooring and remove the need for a distracting bottom track across the floor.
A Smooth Installation Process Factory-direct installation takes the stress out of finalizing your project. The Solar Innovations® Install Team installed the Clear Glass Walls, French doors, and entryway. Our team can install within a six hour travel radius from our Pine Grove, Pennsylvania office. Outside of that radius, we can refer to our extensive dealer network.
With the vision of Bensonwood and the products of Solar Innovations®, the Savings Bank of Walpole became a bright, welcoming space. Customers are greeted with an open, friendly atmosphere. Efficient products create a sustainable building that benefits the environment. Going to the bank just got a whole lot more enjoyable.

The Marcus Mariota Sports Performance Center features an athletic wellness performance facility and an interior constructed of eye-catching glass displays, including a trophy lobby with Tru Vue® UltraVue® Laminated Glass display cases.
The University of Oregon has assembled a massive state-of-the-art showcase to promote student-athlete wellness and to honor one of its Oregon Ducks football alumni, Marcus Mariota.
The Marcus Mariota Sports Performance Center features an athletic wellness performance facility and an interior constructed of eye-catching glass displays, including a trophy lobby with Tru Vue® UltraVue® Laminated Glass display cases.
Mariota was a quarterback for the Oregon Ducks from 2012-2014 and a 2014 Heisman Trophy winner. Today, Mariota is a 3rd year professional National Football League (NFL) quarterback for the Tennessee Titans.
Marcus Mariota Sports Performance Center
The talented design team at SRG Partnership and Senior Designer, Walker Templeton, were the architects behind the Marcus Mariota Sports Performance Center at the University of Oregon.
The breathtaking 30,000 square foot (2787 square meter) renovation includes a new athletic training facility worthy of professional NFL football players. Generous benefactors, such as Nike Co-Founder, Phil Knight, made the $19 million dollar project possible.
The interior of the complex incorporates over 15,000 square feet (1394 square meters) of glass, but it’s not just ordinary glass. Glass lined corridors, entrance doors, and ceilings integrate printed murals and artwork which highlight Mariota’s college career at the University of Oregon.
Some of the decorating techniques used in the project include photo realistic etching, direct printing using laminated glass, and paint filling of surface etched lettering.
Trophy Cases Constructed from UltraVue® Laminated Glass
A major focal point of the Marcus Mariota Sports Performance Center is the trophy lobby which is a 135 foot (41 meter) long glass corridor that reaches 20 feet (6 meters) in height.
All the prestigious trophies that Mariota was awarded during his football career at the University of Oregon are displayed in the center of this impressive corridor. Fabricated by B & L Wood Creations Inc. of Hillsboro, Oregon, each of the 8 cases measure 18” inches (46 centimeters) square and the height of the cases range from 12-40” inches (30–101 centimeters) tall.
Decorative detail was used in every corner of the corridor, but the real artwork is encased in the Tru Vue® UltraVue® Laminated Glass display cases. UltraVue® Laminated Glass was the material of choice since it would severely cut down on unwanted reflections caused by the other non-coated glass and lighting used within the display area, creating the best artifacts viewing experience for guests.
Challenges with Glass Edge Bonding
A unique feature of the glass display cases includes an angled top which helps eliminate the look of a step effect when you enter the display corridor. This feature did however, present a potential problem with fabrication. Edge bonding laminated glass can be a challenge, even for the professionals.
When edge bonding laminated glass is combined with some angles, it multiplies the challenge. Tolerances must be extreme to produce a clean bond with no voids. Any uncontrolled bonding agent would be detrimental to the finished look and could also damage the non-reflective coating on the laminated glass during the assembly process.
Cut and Polished to Precision
Just like in football, precision in glass cutting is mandatory. It starts with the cutting and polishing of the glass. JIT Companies Inc. of Green Isle, Minnesota supplied the quarter inch (6.4 millimeter) UltraVue® Laminated Glass for this project.
Using the clients’ information and requested dimensions for each case, JIT Companies programmed its computer controlled high pressure waterjets for cutting of the glass. This equipment is used due to its high precision and speed producing consistent parts in the process.
The side panels of all the display cases also required a small fixture hole at the lower edge of the glass. This was to be used to secure the glass cases to the base fixture as a security measure for the artifacts.
The cutting was followed by precision edge grinding and polishing that would bring the parts to the final required size, easing the assembly process.
Transparent Assembly of the Glass Cases
The depth and weight of some of the larger units was the most challenging aspect of the assembly. After discussion and testing, it was determined that the best way to fasten the tops to the 4 sides, was to use acrylic 3M™ VHB™ Tape.
JIT Companies provided the water clear (transparent) tape in custom sized lengths for application to the top edge of the cases. The glass top was put in place securing it with an ultra-clear invisible bond. This process ensured that there was no stray adhesive that would have made its way to the inside of the cube, making cleaning difficult, if not impossible.
The Marcus Mariota Sports Performance Center is a visual glass masterpiece at every glance. This project shows how UltraVue® Laminated Glass and some creative ingenuity can be used to cut, polish, and construct even the most challenging glass display cases with striking precision.
Windows are an essential and beautiful element of modern architecture.
Developments in glass technology in recent years has transformed our relationship with the material – no longer are they just small openings in walls, but expansive forms that seamlessly connect us to the outside world and make our homes more comfortable to live in.
If you’re in the early stages of building your dream home, you’ve probably got ‘choose windows’ on a never-ending checklist of things to do, which can understandably be a bit daunting. Don’t worry, we’ve got some awesome tips to help you in making the right choice.
What’s the point?
Glass has different purposes depending on where it is situated. For example, there’s a substanital difference between the glass requirements in your bathroom compared to your living room. The bathroom needs beautiful natural light, but it’s also important to maintain privacy, so a frosted or tinted glass that obscures vision from outside the home might be way to go.
A living room glass set up, on the other hand, will often employ large areas of glass to capitalise on views and create a flow between inside and outside areas.
A (comfortable) room with a view
There’s nothing more stunning than using glass over a larger area, however, the drawback is that it can expose your home to temperature extremes and UV glare. When selecting glass for your home, you should keep in mind that you’ll want to be comfortable all year around.
You might want to consider one of the many glazing, double glazing or low-emissivity products available, which will not only drastically improve the energy efficiency of your home, but keep your home from getting too hot or cold.
Maximise views, minimise noise
Windows not only open up your home to gorgeous views and natural light, but can, at times, also open you up to unwanted noise and visitors. Luckily, there are products that can remedy against that.
Acoustic glass is designed to minimise outside noise, a great feature for people living in high density, urban environment who want a little break from the boisterous natural of city living.
For those who love glass, but are concerned about potential break-ins, security glass is an attractive option. It is harder to break than normal glass and will give you peace of mind that your home and belongings are that little safer.
Glass allows us to create a relationship with the outdoors from the comfort of our homes. We understand that it can be intimidating choosing windows when you don’t have that much experience. However, if you follow the above tips, you’re going to find the process much easier.
Berkeley chemists created a new type of photovoltaic out of cesium-doped perovskite that is transparent at room temperature but turns dark at high temperatures, setting the stage for smart windows that also generate electricity.
A new discovery by Berkeley researchers may soon bring us windows that automatically tint on a sunny day to block the heat while also generating electricity.
Peidong Yang, a professor of chemistry and faculty scientist at Berkeley Lab, and his colleagues have tweaked the chemical structure of perovskite — a versatile material that already rivals silicon-based solar cells — so that the material turns from transparent to opaque when heated and also converts sunlight into electricity.
The invention could lead to power-producing smart windows for buildings, cars and display screens, according to the authors of the study, who reported the development today in the journal Nature Materials.
While the sunlight conversion efficiency of the material — an inorganic halide perovskite with added cesium, lead, iodine and bromine — is still low and the transition from transparent window to opaque solar cell requires heating the window to the boiling point of water, Yang is already at work on versions that work at lower temperatures and with higher conversion efficiency.
“This class of inorganic halide perovskite has amazing phase transition chemistry,” Yang said. “It can essentially change from one crystal structure to another when we slightly change the temperature or introduce a little water vapor.”
Perovskites have been a focus of much research lately because, with the right admixture of chemical elements, they work as very efficient solar cells, converting light to electricity. Tweaking the chemicals in the material also changes the transparency.
Last year, researchers created a perovskite solar cell that changed from transparent to opaque when heated, though the efficiency of solar conversion to electricity dropped drastically after several cycles.
Yang’s new material retains its conversion efficiency after many cycles between transparent and a reddish tint.
“The solar cell shows fully reversible performance and excellent device stability over repeated phase transition cycles without any color fade or performance degradation,” said Minliang Lai, a graduate student in Yang’s group. “With a device like this, a building or car can harvest solar energy through the smart photovoltaic window.”
“It’s an attractive idea that you would have the solar cell capability and the smart window at the same time,” said Michael McGehee, a Stanford University materials scientist who was quoted in an article about the development that appeared in the journal Science.
The shop fronts inside the building are in toughened or laminated safety glass and reinforce the striking architecture of this light-flooded shopping mecca. Some of the facades are almost eight metres high and extend over two floors.
A SHOPPING EXPERIENCE WITH A CRYSTAL CLEAR VIEW
With its striking glass domes, the Aquis Plaza shopping centre at the heart of the Aachen pedestrian precinct in Adalbertstrasse can be spotted from a great distance. On almost 30,000 square metres of retail space, 130 different retailers, restaurants and cafes offer a great shopping and culinary experience.
The shop fronts inside the building are in toughened or laminated safety glass and reinforce the striking architecture of this light-flooded shopping mecca. Some of the facades are almost eight metres high and extend over two floors.
The Aquis Plaza in the heart of Aachen was designed to offer special views into and out of the building and above all a combination of shopping and indulgence. The shopping centre cost a good EUR 290 million to build.
One of the key structural and design elements is special glass in various facets, which floods the retail levels with huge amounts of daylight. It also offers visitors a special experience of space: A passageway with glass roof and views to the sky connects the two buildings of the centre from Kaiserplatz to Willy-Brandt-Platz.
From the inside of the complex in the area facing Adalbertstrasse, you can enjoy an impressive view of St. Adalbert’s church on a rock on the opposite side.
SHOP FRONTS ALMOST EIGHT METRES HIGH
The 130 shops including shop fronts are also a key element in the special overall concept for the centre. For 17 of these shops, experts from Cristalux undertook the assembling and production of the glass facades. Some of the glass facades are 7.70 m and extend over two floors.
They are made of laminated safety glass consisting of two 8 mm thick panes of toughened glass connected with an ultra-thin film.
“Safety is the top priority. If the glass should break unexpectedly the broken fragments adhere to the film. The risk of injury is therefore reduced to a minimum,” explains Cristalux Managing Director Reinhard Schäfer. In addition, when the glass breaks there is still a residual load-bearing capacity and as a result a certain protective effect.
Cristalux, which is part of the Arnold Glas Group, installed almost 700 m2 of laminated and toughened safety glass in the Aquis Plaza in the form of 152 casements and fixed elements, 22 skylights and a roller door. For shop fronts up to 3.70 m high, 12 mm thick clear toughened safety glass was used.
“All stores have their own requirements and specifications, so every glass structure is individual and has to meet specific standards,” says Schäfer.
FRAMELESS FACADE THANKS TO POINT-FIXED GLASS
The Cristalux specialists also assembled the hardware and frame systems. Some of the facades are point-fixed: Attractively shaped holders in stainless steel, which are joined with a substructure via small drill holes in the glass, are the only fixings visible on the surface. This results in a frameless facade that meets the most stringent requirements for transparency.
Schäfer is well aware that shop fronts are not just about extensive project planning expertise and product quality, but also about reliably adhering to the generally short design and execution schedule. To be able to execute such projects smoothly, glazing for shop fronts has become an area of specialisation for Cristalux.
The new TF-580 cap gives an improved aesthetics to the GlassFit SV-1402 aluminum profile, by covering the external mounting holes of the profile blending itself with the rest of its surface.
Its grey color is very similar to aluminium, so both elements fit perfectly integrated.
TF-580, made of low density polyethylene, will perfectly withstand extreme weather conditions and direct sunlight exposure thanks to its UV filter, that provides high stability versus ultraviolet radiation. Thus, the TF-580 cap reveals as perfect for glass railing projects, both indoors and outdoors
Installation process is quite simple: no tools are required for the job. Just insert the cap into the hole in the profile by hand and press it manually, so that it stays fixed. To remove them just use a flat screwdriver.
Dimensions: 25mm diameter
Material: LDPE (Low Density Polyethylene) with UV filter
Iranian manufacturers are actively mastering the global glass market, paying special attention to new technologies.
Iran’s Nanotechnology Initiative Council reported that the number of countries importing Iranian glass and mirrors in 2017 increased to 35. Iran’s industrial group-supplier of glasses managed to enter the markets Germany, Italy, Sweden, Croatia, Poland, Greece, Spain, United Arab Emirates, Azerbaijan, South Africa, Tanzania, Brazil, Canada, etc.
Iran has mastered the technology of applying heat-saving and multifunctional coatings, which allows it to compete in the segment of high-quality glass. Iraqi manufacturers of float glass have 15 production sites in the country and abroad, which allows them to deliver to the countries of four continents – Eurasia, Africa, North and South America.
Iranian glass promotes the brands Eco Gold, Eco Bronze, Eco Blue and Eco Silver, which differ in the shades of the coatings.
Iran is developing a lot of activity in the global market for transparent float glass due to lower prices. The key market for Iran is India. The government of India was forced to impose anti-dumping duties on Iranian glass to protect the interests of its producers. The petition for imposing duties was signed by Saint Gobain India, Gold Plus Glass Industry and HNG.
The main trump cards of Iranian producers are the low cost of labor (and hence production) compared to the European one and the convenient geographic location from the point of view of supplies to the countries of Asia and Africa.
About 30% of the produced float glass is exported, as domestic consumption lags far behind production. It is rather difficult to reduce production – the furnaces can not be turned off, otherwise the glass will solidify and disable the equipment. To stop the equipment it is required to preserve. Therefore, any fluctuations in demand cause serious difficulties.
Export growth and access to foreign markets in recent years is associated with a partial lifting of sanctions: in 2015, the US allowed third countries to trade with Iran. But it’s not just the lifting of sanctions, but also the willingness of the Iranian state to support local producers, including the glass industry.
Brio’s adjustable hinge set, XY is ideal for French door applications as the innovative design allows quick installation of the discreet, surface mount hinges on timber and aluminium panels while providing easy vertical and horizontal adjustment without removing the door.
Reducing the adjustment to only 2 planes means the compression between panel and weather seal is unbroken so systems can maintain energy-efficient performance.
The XY hinges are available in multiple finishes with a choice of cast alloy for 50kg applications or stainless steel for 100kg. Hinge sets can also operate with Brio’s exterior folding system Weatherfold in either top hung 4s or bottom rolling 4c installations.
ODL, Inc. introduces Dialogue Layered Glass, an innovative line of designer decorative and privacy doorglass that offers subtle beauty with a surprising twist.
ODL, Inc.(ODL), a leading building products supplier of decorative and clear door glass and entry treatments, introduces Dialogue Layered Glass, an innovative line of designer decorative and privacy doorglass that offers subtle beauty with a surprising twist.
Named for its interactive design, Dialogue takes on a personality of its own as layers of glass interact with one another, with light and with movement. Each pattern is created by printing subtle designs on interior layers of the insulated door glass, which adds dimension to the pattern.
The Dialogue line was developed in collaboration with Observatory Studio, a Providence, Rhode Island design firm that works closely with other brands in the design industry, including the famed Rhode Island School of Design.
The firm’s principals, Ayako Takase and Cutter Hutton, were tasked with creating dynamic doorglass designs that compliment a range of architectural styles and design aesthetics.
Each of the six ceramic frit patterns change form and move depending on the amount of light coming through and depending upon the viewer’s vantage point.
The patterns are said to interact because of the way they seemingly come to life with changes in light and movement, revealing shapes and dancing shadows that engage in a dialogue with the various layers of doorglass and with the surrounding architecture of the home.
Dialogue patterns include:
Banter– a small-scale pattern of overlapping diagonal lines, which create a woven design that zigzags across the layers of doorglass. From a distance, the fine, threadlike lines give an illusion of a fully frosted glass.
Brainstorm– an exterior vertical pattern couples with an interior chevron motif to appeal to both mid-modern and modern design sensibilities. Brainstorm’s appearance is both subtle and substantial.
Chatter– a repetitive pattern of dots and lines makes this design read more like a texture. The shadow effect gives this doorglass a playful aesthetic.
Converse – a stencil design that hints of keyhole arches, commonly found in Moroccan architecture, at first appears to be cut glass. The clear and frosted glass layers interact to create striking shadows and a high privacy range.
Repartee– frosted layers combine with a geometric grid of shapes to create a lively interaction that changes with light amount and vantage point. The design plays with both movement and opacity.
Whisper– scrolled patterns introduce the refined and graceful qualities of calligraphy to doorglass. A play between frosted and clear glass layers creates gentle, quiet movement.
“We are thrilled to collaborate with Observatory on the launch of Dialogue Layered Glass,” said Amanda Fowler, national marketing manager, Pro Channel at ODL. “The designs serve two purposes: a privacy element gives the glass a sense of utility; and the unique shadows emitted from the patterns and translucency of the glass make it an engaging and striking design element. It is as beautiful as it is practical.”
Dialogue Layered Glass also responds to homeowners’ requests for privacy in doorglass solutions. The six translucent patterns offer dynamic privacy levels which change based on light and proximity and range from a moderate 3-5 to a high 8-9 on the privacy level scale.
Dialogue complements a range of architectural styles and design aesthetics for both high-end residential and commercial applications. Additionally, the glass is available in 11 sizes, nine of which are also available as Severe Weather glass designed specifically for hurricane-prone or high-wind areas.
The woodland house rests on land with the scent of sun and rain.It erects the development of its transparencies till it looks onto the tops of the branches of ancient trees.
The house of the sea lives the landscape. It bears witness to the succession of natural phenomena, responsive to their contrasts, reflecting and integrating into its transparencies the anger and peace of the elements.
Simplicity is when, in the act of creating the dwelling, matter becomes transparent, a medium for aesthetic values, the stage and theater of representation. Carlo Santambrogio and Ennio Arosio pursue and achieve their design intention in which glass figures as the unquestioned protagonist, excluding the mediation of supports that would challenge its leading role. “That image is symbolic,” they comment. “We’re portrayed standing on a transparent sheet of glass. We’re on the upper floor of the Milan showroom, in reality absorbed into a dimension which effaces every distinction between spaces and relates the interior to the setting outside, the urban context. So often, at least virtually, the boundary line vanishes, and we receive the impression of an unbroken vision.
It is then that we ask ourselves about the applications most relevant to the project. And we realize everything is possible in Simplicity, everything can be achieved, provided it embodies a sensitive interpretation of the basic function aimed at satisfying aesthetic needs. The Plexiglas joint makes it possible to combine and assemble the sheets of glass, defining architectural works which are one the development of the other and are integrated in and adapted to the most disparate settings.” “The outside world, nature, landscape, penetrate, thanks to glass and its abstractness, into the intimate or private realm inside, and there play, freely as a component of the atmosphere.” Hence the dream, notes Jean Baudrillard, of living “in a garden in close intimacy with nature, experiencing the charm of every season.” In the words of Wim Wenders, “most of the buildings that are built in big cities are not the fruit of a dream… All you see are huge concrete blocks, tasteless blocks.” And Italo Calvino: “The invisible cities are a dream born from the heart of unlivable cities.” Stupid, obsolete fortresses, those blocks of concrete constitute much of the world’s metropolises and megalopolises. Even though “in various efforts to run counter to its own founding act,” in the words of Gianfranco Maraniello, “contemporary architecture has gone so far as to propose the negation of the ‘wall’ itself, both by creating ‘open’ and sometimes unlivable spaces and by modifying or creating living spaces without circumscribing them as certain defined rooms, or by making the boundaries of its constructs uncertain.” This is confirmed by Jean Baudrillard: “Glass is the miracle of a fixed fluid, of a content that is also a container, and hence the basis of the transparency between the two: a kind of transcendence which, as we have seen, is the first imperative in the creation of atmosphere… Indestructible, immune to decay, colorless, odorless… glass… is to matter as vacuum is to air… Glass is the basis of a transparency without transition: we see, but cannot touch. The message is universal and abstract.” Carlo Santambrogio observes: “On brownfield sites, row up row of factories in serried ranks testify to now remote times, when manufacturing was still carried on in urban districts.
Today obsolete factories can be divided into apartments, known as ‘lofts.’ Real-estate dealers promote them as open spaces which, after undergoing the usual restructuring, will substantially change their nature and be organized as condominiums. This is because it is impossible to understand a single building regardless of its context. Open space cannot therefore be bounded by walls. Those walls testify to a history that is unchangeable: they are a landscape and form a frame of reference, which has to be respected and enhanced. Finding myself having to deal with one of these factory buildings, I immediately thought I could not turn it into a home of a traditional kind, or appeal to other illusory connotations. I would have to detach myself from those walls, leaving them open to the sky, and seek to create a dialogue with their history, even if I had to reinvent it. The idea could hardly help being related to transparency, the fascination of the material par excellence. Hence the garden with plants and flowers. Glass reflects and integrates the colors of the roses, jasmine and oleanders, of the sky and the clouds chasing each other across the blue; it distinguishes the light of dawn from that of sunset. All this in the city, the privilege of incommensurable moments amid those rows of factory buildings on a brownfield site. Glass endows a form on the load-bearing girders, floors, roof and walls. The staircase shines with the greenery of plants. Sunlight passes through the slabs that form the great pool. Colorless, the supreme material justifies the conception of the whole habitat, of the structure — the container — and of the furnishings — the content. Macro and micro are integrated in harmonious cohesion.
The composition of the kitchen space is exemplary. Seemingly immaterial, a landscape within the landscape, it reflects the glow of flame, the green of the vegetable garden, the pink of crustaceans, the red of meat. The interplay of transparencies heightens the senses, revealing food, when there is an occasion for it, a gratifying embodiment of desire, the achievement of the most exclusive life style.”
“No house,” wrote Frank Lloyd Wright, “should ever be on a hill or on anything. It should be of the hill. Belonging to it. Hill and house should live together each the happier for the other.” It has to belong to the where in everywhere. So, if the house is in the wood, the wood is in the house. This is not playing on words, but a confirmation of the relationship between two representations, one natural the other artificial. “Remember,” said Ludwig Wittgenstein, “the impression made by good architecture, which is to express a thought. You feel the urge to accompany it with a gesture.” The gesture of building is an extremely musical gesture. Good architecture is good music.
Carlo Santambrogio recounts: “Living in the forest day and night, in sun and rain, in wind, ice and snow, realizing the dream of making the forest the house so as to live in the forest. A house that must never be an object that can just be set down anywhere, but rather a place of enchantment, of wonder, of amazement. Three floors of vertical development, for the sake of all-round vision.
Going up the transparent stairs makes you feel you are climbing into the tree tops. In the house, where the forest is at home, in the shower cubicle the water patters on the skin like the drumming of rain in spring, the dormeuse is shaded from the warm summer sun, the scent of autumn is in the mushrooms on the table, winter in the sudden darkness that surprises the day.” Nature is onstage in the theater of transparencies, where snow, ice, rain and sun alternate in the limelight. Whoever lives here, enlivens the scene, lives by it and feels the excitement. His behavior is more like that of an actor than a member of the audience. Another house is that of the sea, where, in the words of Rudyard Kipling, we “comprehend and enjoy the dry chorus of wave-tops turning over with a sound of incessant tearing; the hurry of the winds working across open spaces and herding the purple-blue cloud-shadows; the splendid upheaval of the red sunrise.” And again Carlo Santambrogio: “The house of the sea lies along the promontory without clinging to it: it appears as if suspended. The whole structure reflects the rugged terrain. Under the slabs of the floor there plays a wind that bears
the tang of sea salt and carries the cries of the gulls. The rock has a sense of sturdiness, of safety. And making landfall here is the first frame of reference in the setting, while the sea is a boundless vision. Whoever dwells in the house of the sea rests in port and dreams of setting sail again.
Both transparent, a great bed stands out next to a bookcase, where even the books tell of the sea.”
Because, says Kipling again, “The dullest of folk cannot see this kind of thing hour after hour through long days without noticing it.”
