Two solutions to reduce the problem of noise diffusion in the office: the sound-absorbing walls.

Among the many customizations that VetroIN has designed for your office furniture, there are also sound-absorbing walls that can limit the transmission of noise between one room and another.

The problem of the echo, of hearing the conversations from the next room, of not being able to work in silence and serenity because of the background noise, is in effect one of the most annoying in the office, especially if it is large, especially if it is crowded.

VetroIN has studied these sound-absorbing walls to solve the problem, without sacrificing aesthetics and design that the company always guarantees.

What features do these sound-absorbing walls have?

1 – sound reduction thanks to the insertion during the lamination process of PVB transparent films with increased thickness
2 – enhancement of noise absorption by overlaying glazed elements with elements in milled wood or polyester fiber panels covered with fabric (to be personalized)

Based on the extent of sound diffusion, one or the other or even both solutions will be chosen.

As always, we invite you to consult our website, at the vetroINnovazioni page you will find the category dedicated to acoustic panels. And right here you will have also the opportunity to see some pictures of recent realizations of sound-absorbing walls.

A design inspired by an Abu Dhabi skyscraper, and brought to life in the prototype area of Maple’s Stockport factory, will soon be making a big impact on Salford’s skyline.

Maple are working with Morgan Sindall and architects AHR on a dramatic façade for a new multi-storey car park.

Made up of individual ‘kite-shaped’ aluminium panels, striking 3D hexagons will cloak the new building, which will be a far cry from the ugly concrete car parks of the past.

However, with imaginative concepts comes complex manufacture. So, Maple’s technical design team has been working closely with the architects since May 2016 to agree design and colour, and the intricacies of fixing and installation. Samples were created, reviewed and refined in our factory to avoid the costs and delays of making changes on site.

As with AHR’s original design in United Arab Emirates, the façade will provide solar and glare protection ― from all angles ― but still allow light to enter the building.

The project is due for completion in December 2018.




The insulated glass window is one of the most important components of modern life. On the one hand, it connects us with our environment by allowing us to see it (instead of a wall). On the other, it protects us from undesired environmental influences such as cold, heat or noise. Its transparency thus obscures the fact that insulating glass consists of a variety of materials, which only as a whole can satisfy the various demands of technical, highly complex end products. Each of these materials shows how it reacts once the product is assembled, whereby this reaction also always depends on how the raw materials were initially processed. And so glass too has a past life; everybody knows that luck and glass shatter easily and luck can rust easily… but glass? Dr Michael Emonds considers the possibilities.

The surface of freshly produced float glass is highly reactive. While the glass is being stored or transported, it may react with humidity that has penetrated the spaces between the layers of glass, which can lead to highly adhesive blotches of corrosion. If the corrosion is distinctive, the glass cannot be processed any further. The level of corrosion depends on the humidity, temperature, conditions of storage and transport and the quality of the glass (composition, hydrolytic class etc).


Furthermore, corrosion in the early stages is not recognizable to the eye and only becomes visible when the glass is processed further (e.g. by low-E coating, silvering or tempering). In the Chemetall development laboratory, corrosion-protected sheets were compared to non-protected sheets as to any reactions following application of a thin film coating (figure 1). In stress tests, the untreated sheets showed signs of flaking much sooner than sheets that were given an initial protective coating. The disturbance in film build-up that was responsible for this can, during further processing into insulation glass, also have a negative effect on the sealant on the glass surface


Or electrochemical action’. This definition can apply to the reaction undergone by float glass due to environmental humidity during storage or transport (figure 2).

HOW CORROSION OCCURS The effects of water on glass surfaces is a combination of two processes, which take place almost at the same time; the exchange of H+ ions in the water for Na+ ions on the surface of the glass (initial phase) and an alkaline reaction by the hydroxyl ions left over in the water to the silicate network on the surface of the glass (corrosion stage) (figure 3).

In the initial phase, the silicate network remains unchanged and an SiOx-rich layer with low Na+ content builds up. A constant replacement of  the layer of water adhering to the upper layer of the glass, eg due to rain then leads to a stabilisation of the glass.What happens however, when a thin film of water remains on the glass over a longer period and is not constantly replaced? The sodium hydroxide is no longer washed off by the rain but becomes more concentrated. When the pH level reaches 9-10, the glass structure starts to decompose. This process, called glass corrosion is consolidated by high humidity in connection with vastly varying temperatures (temperatures below dew point).003


HOW TO RECOGNISE CORROSION While corrosion in the end phase is clearly recognizable by multi-coloured changes on the surface of the glass to white coloured deposits, the initial phases of corrosion are not visible but make further processing of the glass difficult, if not impossible.

Corrosion in the initial phase is characterised by various physical changes to the surface of the glass, e.g. a change in thermal expansion, refractive index and surface energy. Furthermore, already existing microscopic cracks are strengthened by the corrosion. A porous layer several micrometers thick occurs, in  Which various deposits can settle, making further processing difficult. Physical methods of measuring, such as ellipsometry, IR, REM, AFM or the measurement of the contact angle allow a very sensitive location of corrosion (figure 4).



In order to reduce production loss due to corrosion, the glass industry uses various procedures, e.g.:

  • Only freshly produced float glass is used for further processing. However, this is only possible for float glass manufacturers, even though there are problems for them also, eg in thick glass processing.
  • The glass is stored and transported at a constant temperature and humidity (figure 5). Due to the capacity of the float glass lines and the jumbo sizes produced, this solution is only partially applicable.
  • The stacks of glass are sealed off at the ends in order to prevent humidity from entering between the glass sheets. This method is mainly used to transport laminated glass but is hardly ever used for untreated glass.
  • The glass is polished prior to further processing. The surface of the glass is refreshed using a suspension of cerium oxide, aluminium oxide or other oxides, before being given its silver plating or low-E coating finish. Because a fresh glass surface is very reactive, further treatment must take place as quickly as possible.
  • Finally, it is also possible to reduce the pH value on the glass surface using acid. Mixtures of separating agents with adipic or boric acid in various concentrations allow the separation of the glass sheets on the one hand and the application of a corrosion protection on the other, in the same phase. Recently, people have started to apply a liquid corrosion protection, applying the separating agent in the second phase (figures 6 and 7). In this way, a better distribution of the acids on the surface is achieved. Due to the use of polyvalent acids, the buffer capacity of the protective acids can be improved.

Much can be done to protect glass from corrosion but it is not possible to exclude it completely. While corrosion in the initial phases can be removed using suitable polishing agents, visibly corroded glass can no longer be repaired to a reasonable standard.


As float glass available on the market can vary, (e.g. they can possess various hydrolytic qualities, or the year of manufacture may simply be different), polishing, in order to clean the surface of the glass is surely a reasonable step to take prior to further processing of the glass into a higher quality product. It must be pointed out once more that due to initial corrosion, defects on the glass surface will be increased, which may not become visible for some time after the end product has been completed unless silver layers start to flake off, colour defects of low-E glass or adhesion problems with insulating glass occur. Chemetall’s experience shows that corrosion can be reliably held back using tailor-made, anti-corrosive interleavants. However, one must remember that the corrosion protection must be totally washable, leaving no residue, prior to further treatment. The same applies to all other auxiliary agents such as cutting fluids, separating agents or coolants and of course, contamination of the glass surface due to dust, fingerprints, roller prints, gloves etc. This is no longer possible using just water alone; special detergent, used for treating glass is also required. It must also be possible to wash this off completely.

As can be seen, things can go wrong right at the beginning in the final production of insulating glass windows. It is certainly not easy to find a solid, overall approach. However, each individual stage must be carefully observed and its effects on the subsequent stages of the process assessed if one wishes to locate defects and to avoid them.

VetroIN invests in safety every day, so were born the anti-seismic glass walls INWALL.

As always we support in our weekly articles, that VetroIN invests a great deal in the research sector, not only in terms of aesthetics and technology, but also in terms of safety. In particular today we talk about our anti-seismic glass walls.

Earthquakes are natural phenomena that cannot be predicted and always scares a lot. Generally when they arrive they always cause big disasters, they raze entire countries to the ground and too often they also make victims.

We from VetroIN, creators and furniture manufacturers, have the duty to search every day for solutions to secure the environments and make them as resistant as possible to these “oscillations” more or less strong. Thus were born the anti-seismic glass walls of the INWALL collection, with many of the structural elements patent pending.

This collection was presented on the occasion of the tenth anniversary of activity and great success of our company. It represents a revolution in all aspects: from aesthetics, overcoming the limits of matter, to safety, with these cutting-edge anti-seismic elements.

Architects, contact VetroIN if you have to create a truly innovative and above all safe furniture for important offices, not already old at the time of the project! Aesthetics, technology and safety… these are our new anti-seismic glass walls.

Create an open work environment even with separated office and conference rooms – Auer Weber architects and artist Brigitte Waldach faced up to this Task in regards to the new construction of the Sparkasse Allgäu.

The new Sparkasse Allgau proves impressively that office buildings don’t have to be dull and cold.

Sparkasse Allgau KemptenAuer Weber architects and artist Brigitte Waldach created a superb symbiosis from a new construction and the adjoining city park, with peaceful single offices and spacious atmosphere by using glass walls, subtle coloring in black-white-red and artfully, and loosening design with digital print onto glass.

The art-on-the-building-project spreads out on four floors. Thereby the use of the premises is already recognizable by the various designs. The offices and conference rooms are designed as open communication rooms with the motifs tree and cloud.

Whereas the management offices are decorated with grasses. By choosing such natural motifs, the building integrates itself perfectly into the adjoining city park. Another highlight: there are quotes and excerpt from a poem in the motifs.

You can find more information to this project in Thiele Glas’ reference section.

AluK’s new Luminia Select Partner network was launched late last year with a number of fabricators selected to join as founder members.

They were all individually invited on the basis that they share AluK’s ethos and values in targeting the premium sector.

These companies currently have priority access to AluK’s Luminia product range, including the exciting new F82 bi-fold door, which is making huge waves in the aluminium market and already looks set to become the new benchmark door in the premium sector.

What is interesting about the Luminia Select Partner members is the mix of fabricators who are members. They vary in size and business profile and were chosen primarily because they have the most experience and best access to the premium market where the Luminia range is targeted.

Crucially, they are also the ones whom AluK believes have the resources within their businesses to effectively support the sales and marketing of the premium product range in both the trade and retail markets.

AluK’s Managing Director Russell Yates explains the strategy: “There’s such huge potential for aluminium at the moment that it’s vital we partner with the right companies to make the most of the massive opportunities which exist. With the Luminia Select Partner scheme, we have chosen the companies who we think best reflect our ambitions specifically for the premium range, and who share our vision for growing aluminium’s market share without sacrificing their own or their customers’ sales margins.

“It is not our intention to restrict membership – other companies will certainly be invited to join the network in the future if they fit that profile, and we’re getting plenty of requests to join, but we have no plans to massively expand. The important aspect for us is that this should be a genuine partnership between system supplier and fabricator – it is much more than a logo for companies to use on their website, or a lead generation vehicle like some other schemes. It is a way for us to provide very targeted support to individual businesses so that they can generate really meaningful and sustainable growth in aluminium and achieve our goals for the Luminia range together.”

The benefits for those companies who are invited to join the Luminia Select Partner scheme are immediately obvious. They get marketing and business support direct from AluK to promote Luminia products – starting with the game changing F82, they get help from project consultants in targeting and winning business, and they can also access AluK’s vast range of technical support services across design, fabrication and quotation. They are also of course, provided with bespoke product training at the new AluK Academy.

The response from members at the launch event last October and in the months that have followed has been hugely enthusiastic. Most have already attended the partner training days at the Academy centred on efficient fabrication of the F82, and, now that they have launched the door to their own customers, orders are exceeding expectations.

Russell Yates adds: “AluK has invested massively over recent years in our facilities and our processes and we have never been more streamlined or more focused on what we want to achieve in the UK. Our drive for cutting-edge aluminium innovation and market leading customer service is evident not just in our ongoing product launches but in our determination to create a partner scheme which has real tangible value for members.

“We are at the start of an exciting journey with the Luminia range with lots more premium products planned and even more customer service initiatives, which will give us an even bigger point of differentiation in a market where there is still such massive potential. To be able to share that journey with some of our most loyal and ambitious like-minded customers is going to be a real thrill.”

The AluK Luminia Select Partners are: Alpine Window and Door Systems, AluFold Direct, Arkay Windows, Capital Windows Doors and Conservatories, Climatec Windows, Complete Aluminium Systems, CWG Choices, Duration Windows, EYG, Hadleigh Glass, Iceni Windows, IQ Glass, Nolan, Quantum Windows, Rhino Aluminium, Sliders UK and Whiteline.

As it is World Green Building Week, I would like to celebrate with you the overlooked heroes that can help us win the fight against climate change while making our life more comfortable: The buildings we live in.

Why should we even care about buildings?

Buildings have a huge impact on people, on our planet and on the economy.

We spend up to 90% of our time inside buildings and that means they strongly influence our health and wellbeing. Indoor air quality, acoustics, daylight, temperature…these are some of the parameters that influence the way you learn, play, work, and sleep.

Buildings are also responsible for nearly 1/4 of the global carbon emissions leading to climate change and this figure could rise to 50% by 2050 if we don’t do anything. The good news is that the solutions already exist to drastically reduce this impact…they just need to be implemented.

Finally, the construction industry is one of the world economy’s largest sectors, with $10 trillion spent on construction-related goods and services every year. It also employs about 7 percent of the world’s working-age population.

So what is a Sustainable Building?

A sustainable building is a building that takes into account People, Planet and Prosperity across all the stages of its life cycle: from raw material extraction, to construction, use and even demolition.

The European Commission developed recently the Level(s) initiative, defining the priorities for sustainable buildings:

  • Greenhouse gas emissions throughout the building’s life cycle
  • Resource efficient and circular material life cycles
  • Efficient use of water resources
  • Healthy and comfortable spaces
  • Adaptation and resilience to climate change
  • Life cycle cost and value

How do we build more of those sustainable buildings? 

The market for green buildings is growing. A recent study shows that in the Nordics, the share of certified green buildings is expected to double for new construction (from a bit less than 25% today to more than 50% in 5 to 10 years) and even more for existing buildings (from around 5% today to more than 20% in 5 to ten years).

The question is: how do we sustain this growth to ensure that sustainable buildings are becoming mainstream?


Firstly, more collaboration across the value chain is needed. If we want to build more sustainable buildings we have to change the way we work and start new partnerships across the value chain. End-users, investors, architects, contractors, construction product manufacturers, all can bring input and knowledge to the table.

This is why Saint-Gobain is strongly involved with the Green Building Councils (GBCs)across the world. We are member of more than 35 countries worldwide and in the Nordic and Baltic region we participate in all seven countries and are board member in Sweden, Denmark and Latvia.

National GBCs and the WorldGBC have made an amazing job in creating forums for discussion across the building value chain. This World Green Building Week is just one of many example of how to create momentum and discussion around sustainable construction.

Locally, innovative projects emerge and actors unite to work on solutions for the future. The REBUS (Renovating Buildings Sustainably) project is a partnership representing the entire value and knowledge chain of the building sector in Denmark. The work is aimed at social housing buildings and targets are to reduce energy consumption in the existing building stock by minimum 50%, achieve reduction in resource usage by 30%, and increase productivity 20% by industrializing building renovations, and at the same time ensure a good and healthy life inside the buildings.


At Saint-Gobain we are willing to play our part in the transition towards more sustainable buildings and the circular economy. Our mission is to enhance the wellbeing of people everywhere, by combining:

•            Comfort, which answers today’s individual needs &

•            Sustainability that addresses tomorrow’s collective challenges

We develop solutions that contribute to green buildings, such as LEEDBREEAMHQEor DGNB certified buildings to only name a few. Our ISOVER glasswool is made of up to 80% recycled glass. Our Gyproc Activ’Air plasterboards decompose Volatile Organic Compounds (VOCs) to enhance indoor climate. Our Weber Nordic floors have been redesigned leading to a CO2 footprint reduction of up to 36%. Our Ecophon solutions contribute to better acoustics environments in schools, hospitals and offices. Our SageGlassdynamic glass improves visual comfort for occupants while reducing energy consumption.

As data sharing is key in the transition towards more sustainable buildings, we provide transparent information about the environmental impact of our solutions. Our Environmental Product Declarations (EPDs) are third party verified and available for our customers willing to calculate the impact of their buildings.

Finally we are working on designing more sustainable products. The Saint-Gobain Eco-Innovation approach aims at bringing differentiating value to our customers by developing innovative solutions that are having a better impact on People and Planet. More than 600 people have already been trained worldwide and are ready to co-develop the solutions of tomorrow.

To conclude, it’s up to us to make the buildings around us a solution rather than problem in the fight against climate change. For this World Green Building Week 2017, get involved and learn, share and lead the way!

The Carnarvon Fuse Art Collective presents a stunning public art piece digitally printed onto low iron, cyclonic glass.

More than a splash has been made at the Parap Pools, Darwin’s newest aquatic and leisure centre. Designed for the community as a multi-functional facility that draws people together for leisure, art, activity and national competitions – it also includes a two part artwork ‘Under The Surface’ by renowned artist, Jill Chism.

Art and architecture are seamlessly intertwined to express notions of fluidity in this tropical setting: The architecture complementing and informing the art to create a unified harmony of material across the 70m zig zag façade.

Chism worked in close collaboration with Liquid Blu Architects to integrate the built and decorative form of the façade and entrance sculpture into a holistic approach with the building design.

One component of this, being in the form of a bold glass sculpture, an expressive wave-like statement at the entrance, for which Cooling Brothers was engaged to supply DigiGlass In-Glass Printing.

Under The Surface - DigiGlass Makes Waves in the Northern Territory

This striking entrance sculpture explores our experience with water. Chism drew inspiration from all aspects of the activity, action, sounds and movement in and around the aquatic environment.

Carefully observing and documenting the visual and sensory experience, highly detailed imagery was created by Chism for DigiGlass printing. This was applied to a sculptural shape inspired by the motion of an ocean wave.

Cooling Brothers produced the 12 laminated glass panels, which stand arranged in fluent motion as reflections and light play upon the eye, creating a sense of aqueous movement as the viewer moves around the work. Chism describes :

Visually the expressive engagement with water creates distortion, reflection and the formation of a surprising tracery of patterns and reflected light…what we see is illusory and impermanent. The entrance sculpture and patterning on the façade were designed to replicate the sense of this activity movement and light.

As one of the first projects produced on the new printing line at Cooling Brothers, we were very excited to see the glass installed into such a significant and considered artwork in the Northern Territory.

Check out the clip to hear Chism describe the importance of community engagement, her collaborative approach that went into seeing the project come to fruition, and some on-site action.












All offices must be well ventilated. To meet increasingly stringent Health and Safety regulations, a continuous supply of fresh air is necessary.

Adequate ventilation is also a pre-requisite for a healthy and productive workforce. Studies show that workers who are comfortable in their working environment are over 60% more productive. Workers in a well-ventilated office are also less likely to become ill.

There are several methods to ventilate an office space. The best choice for you will depend on the office size and the range of equipment in use. An office with lots of staff, computers, and machinery will generate more heat, thus requiring better ventilation. When ventilating your office, it’s important to consider these options.



natural ventilation system circulates air in a building without using a mechanical system. External air is directed through the internal space by using advanced control systems.

The control system can be connected to a variety of different sensor types including rain, wind, and temperature sensors. The control system can also be linked to a manual controller such as a switch or remote control to activate the ventilation process.

When designing your natural ventilation system, you must consider several factors. These include:

  • Building location – Whether it’s urban or more isolated. Sheltered or exposed.
  • Building height – The higher the building, the more external conditions will influence its natural ventilation.
  • Indoor layout and partitions – The interior set up will both restrict and enable air flow.
  • Window types – The size, shape, and opening arc of any windows will directly affect the ventilation capacity.

The type of natural ventilation system suitable for a building will ultimately be determined by a combination of the building’s natural external environment and the interior layout and building structure.



In the event of fire, all office buildings must be designed to facilitate the safe escape of workers. A smoke ventilation system will release smoke from stairwells, atriums, and corridors to allow a safer exit.

Smoke ventilation systems can be manually or automatically activated. Smoke sensors or smoke alarms can directly link to the smoke vent, automatically triggering its opening when smoke is detected.

Smoke vents can also be manually activated by an emergency break glass point or by a Fire Officer at an override switch. Once the smoke ventilation system is activated, the vent will remain open until all smoke has dissipated or the system has been manually reset.



Alongside Window Actuators connected to natural and smoke ventilation systems, there are a range of independent automatic window opening systems available. Remote window opening actuators are perfect for large office spaces, particularly where windows are situated out of reach at a high level.

Window actuators can be controlled by a selection of switches, key switches, remote transmitters and receivers, and 24V DC transformers. Window automation can be designed and implemented into the ventilation system or work separately to allow increased airflow when necessary.

At Teal Products, we have over 17 years’ experience supplying high quality window control products and ventilation systems.

We pride ourselves on our outstanding customer service and are always happy to offer advice on product specification and installation. When you want to create a comfortable and well-ventilated office space, Teal Products can provide you with the best solution.

Insulating glass was considered an important element of the sustainable design of the shopping mall and its integration into the urban landscape.

“K” shopping centre, Kaiserslautern



The new “K” shopping centre in the heart of Kaiserslautern attracts visitors to a 20,900 m2 retail space with around 100 stores including fashion boutiques, perfumeries and a market hall. The building is part of the “New Kaiserslautern City Centre” Project.

Insulating glass was considered an important element of the sustainable design of the shopping mall and its integration into the urban landscape. The glass supplied by arcon not only improves energy efficiency but also helps ensure a special shopping experience.

For EUR 160 million, Kaiserslautern has obtained a new attraction: The “K” shopping centre brings together numerous retailers from various sectors and as a result complements and/or consolidates the diverse retail landscape of the technology and university town in Germany’s Rhineland-Palatinate region.

It also connects the previously separate pedestrian zones in Fackelstrasse and Mühlstrasse and is therefore a crucial component of the “New Kaiserslautern City Centre” Project. The old Karstadt department store building, which previously stood where the shopping centre is now, has been integrated into the new build.

“K” shopping centre, Kaiserslautern




What is distinctive about the 20 m high new build are the glass structures from arcon, the technology brand of Arnold Glas. “They were designed according to the new glass standard DIN 18008. In this context, structural analyses were decisive and of course also the requirements for extremely high glass quality,” stresses Albert Schweitzer, Plant Manager at arcon.

The glass makes a substantial contribution to the energy efficiency of the building. To achieve the specified g-value of 21 percent, single-pane toughened safety glass, featuring a fine screen-printed dot pattern, was chosen for the 400 m2 roof glazing.

The glass is also treated with the solar control coating ISOLAR SOLARLUX® A70. Combined with the dot patterns, it helps ensure that even on sunny days the building interior remains pleasantly cool.

In addition, it gives the glass a unique neutrality and brilliance. These energy-specific and visual benefits are also typical of the steel and glass entrance facades, which are also coated. In this case, 600 m2 heat-strengthened laminated safety glass was used.

The canopies of the entrance facades, covering an area of 160 m2, also consist entirely of laminated safety glass and blend harmoniously into the glass architecture of the building.

“K” shopping centre, Kaiserslautern



Those who don’t just want to shop but also enjoy the view of Kaiserslautern’s inner city can simply go to the first floor. For the best possible view outside, visitors can go right to the front of the facade on a non-slip laminated safety glass walkway. To guarantee the safety of visitors this glass has to meet special requirements.

“The large number of different glass structures over four floors was a real challenge. Everything had to fit accurately and needed to be delivered in the shortest of time. It all worked out perfectly,” says facade designer Siegmar Christ from engineering firm “EURO-Fassadentechnik” in Bad Hersfeld.

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

140512_FLASH_1949Flood-LancasterAveWindow 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.
