Aluplex - Omkar 1973, Mumbai

OMKAR 1973, Mumbai Project Summary

India’s most luxurious project of 265m + height at 3.75kPa designed by FOSTER + PARTNERS, UK incorporating: ;; Curved unitised glazing, ;; Curved unitised glazed balustrades, ;; Fire-resistant triangular column cladding, ;; Fixed and openable unitised window systems, ;; Mechanical facade using curved aerofoil louvers, ;; Amenity glazing using stainless steel clamps with jumbo-sized glass of 2.1mx 4m in height, weighing more than 120 kg each,

;; Back of the house louvers and curved fire resistant column cladding. 1. This Project is constructed in record time with more than 100,000 metre square completed in less than 12 months. 2. The curved geometry of the building required the use of precision aluminium bending and fabrication constructed to the tolerance of just 1mm. The curved glasses were especially imported which were also curved

to minimal tolerances in order to achieve the matching geometry for bonding with curved aluminium framework using methods that have never been done before in India. 3. At locations, the structural RCC slab curvature did not meet the required tolerances, and thus, the curvature of each slab was surveyed at intervals of 300mm using a Total Station Surveying Instrument and thereafter, different types of extension brackets were designed to accommodate the varying curvature in each slab. 4. These variances in civil construction were accounted for using the adaptations in the complex bracket design that then created a flawless facade.

DLF CYBER PARK, Gurgaon Project Summary This building in the heart of the central business district of Gurgaon is a three-building commercial campus that incorporates 40,431 square metre of glass. The project has very large unitised panels of 4.4m height due to the huge ceiling heights. The building seems to be floating on a boatlike red aluminium cladded float with 3-dimensional curved cladding. The execution began in May 2018 and the project is expected to be completed for fit-outs by March 2019.

Glass Spacer: More Transparency for IGU Joints sedak makes facades’ joints disappear visually In the style of a manufactory, sedak, the expert in oversize glass, has developed the reputation to develop special solutions with potential until series production is possible. The latest development are insulating glass units with glass spacers.


hus, the German glass manufacturer makes the usually typical joints disappear visually. Instead of the conventional, up to four centimetres wide, black joint out of a plastic spacer and silicone, the new glass spacer is used for two visible sides. The result is a nearly seamless overall view with maximum transparency and the same technical characteristics of the IGU. Until now, the almost jointless appearance of large-scale glazing could only be reached with laminated safety glass. sedak was tinkering a year to create the up-to-date solution that would satisfy its own commitment to quality. Because it is based on an extensive research, although the

solution sounds simple. Twenty-five years ago, there were initial tests in the glass industry to build IGUs with spacers out of glass. Few projects were realized which are now in need of rehabilitation. Against this background, sedak started to research with the result that the buildings can now be glazed with IGUs that fulfill not only quality requirements regarding processing and visual appearance but also provide contemporary Ug values. It is a future-proof development for which sedak researched intensely into the right composition and the material properties of the single components. The cavity is hermetically sealed by a special adhesive which keeps the gas in the cavity permanently. Thus, all

required insulation values are fulfilled in a long term and the glass-to-glass joint is hardly visible.

Simple function, maximum effect For the two visible glass edges, the transparent spacer is used. That makes the vertical joint of two glass units disappear visually. For the horizontal joints, which are not visible after the installation into the holding construction, sedak uses a common plastic spacer. It provides a desiccant keeping the cavity dry. “The insulating glass units with a glass spacer extend our portfolio of products and additionally offer, besides our laminates, an exciting alternative with up-to-date energy values,” says sedak’s sales director Ulrich Theisen. “This new level of transparency of glass facades and roofs allows for a more honest and open architectural language.”

About the company

sedak, the glass manufacturer in Gersthofen, Germany, was founded in 2007. The company has developed into the world’s technology and innovation leader for large insulating and safety glass. With a ten-year experience of manufacturing oversize glass and after having increased the level of automation continuously, sedak is regarded as a specialist in this know-how intensive segment.

Innovative products with functional transparency Sedak BAU Innovations: Edge Protection Made From Glass & Glass Spacers For Insulation Glass At BAU, sedak presented two examples of how it has a clear edge in glass construction: firstly with the glass impact and edge protection “sedak clear-edge” for parapets, hand rails and edges of constructional glass building components, and secondly with a glass spacer for insulation glass – “sedak isopure”.


oth of these innovations increase the level of transparency as functional tailor-made detail solutions, especially in all-glass constructions. With “sedak clearedge”, the glass processor based in Gersthofen, Germany, has developed a transparent, aesthetically attractive edging solution for exposed glass edges, for example on glass parapets or hand rails.


Glass Bulletin | January - March, 2019

This special glass strip is laminated onto the edge, providing it with a neat and clean conclusion. With its highly polished sides and absolutely flat glass surface, “sedak clear-edge” sets functional and aesthetic accents. The open edge of the glass composite is protected from the influences of the weather, the laminated-on glass acts as protection against impacts, thus

enabling two-pane laminates where the building regulations previously required three-pane laminates to be used.

It looks like glass, glass and glass With “sedak isopure” insulation, glass façades look even more transparent. These glass spacers,

which are utilized on two sides of the pane, cause the joints between the glass elements to be optically dissipated. “Glass façades with sedak isopure are almost uninterruptedly transparent. In combination with glass fins as supporting structural elements, highly transparent glass façades with up-to-date energy standards can be created,” sedak Managing Director Bernhard Veh said.

Enormously popular exhibits The trade fair was very positive for sedak. This was mainly due to the excellent response from the public. Veh added, “Our stand was constantly very busy. We were especially pleased that four guided tours for architects visited sedak – with more than 2000 exhibitors this makes us feel especially honoured.” Among others, internationally renowned daylight expert Ulrike Brandi brought a group of planners to the sedak stand in hall C3.

Why Does Glass Corrode and What Can We Do About it? By Satya Prakash Rath, 3P Nanopac Pvt. Ltd.

Glass in any of its forms, shapes or applications will corrode on coming in contact with hard water. The effects of weather and corrosion on glass, even on a new car windshield, shower door, window or facade, can be readily seen upon close examination after only a few months of exposure -and after a few years, the problems can be viewed from a distance.


sually, the process begins with “water spots” or staining. By the time one can see these symptoms, corrosion has already done preliminary damage to the molecular structure of the glass. By the time one sees iridescence (a rainbow-like effect), there has been substantial glass deterioration. Eventually, glass may appear foggy or cloudy. An attempt at washing these symptoms away with soap and water will lead to frustration and wastage of time, energy and soap. An attempt to scrape them off with a razor blade will result in scratched (but still foggy) windows, shower doors and facades. Can anything be done about it? Yes. The best thing to do is to prevent the corrosion in the first place by protecting the glass surface with a Diamon-Fusion® coating during or soon after installation at site. If one chooses not to do that and glass becomes corroded, up to a point, the glass be can be professionally restored and sealed. But, while this process will make the glass appear normal, it does not reverse the damage already done, and beyond a certain stage (stage II glass corrosion), attempts to restore the glass will simply fail and the only recourse will be to replace the glass. Corrosion as a chemical phenomenon is complex and only recently has yielded itself to scientific


Glass Bulletin | January - March, 2019

inquiry. The short answer is by exposure to hard water – i.e. repeated cycles of wetting and drying of water on glass. This can be by rainfall, showers, water runoff, cycles of condensation, or even just humidity. Add contaminants, such as pollutants, soap, dust or hard water (especially anything alkaline) and the process can be sped up dramatically.

Examine the illustrations below for a simplified explanation:

Step 1. Water drops form on the surface of the glass. The source of the moisture may be precipitation, water spray, shower or sprinkler, building runoff, condensation or humidity or just wiping cloth. The water had dissolved contaminants

3P Nanopac Pvt Ltd • 2

like alkaline salts from ground water, from pollution or absorption from other materials in its path (masonry, metal window frames, silicone window sealants, etc.).

Step 2. Immediately, soda and other chemicals begin to leach out of the glass and into the water drop, forming a soda solution on the glass surface. Usually, this is a fairly slow process to begin with because the pH has not reached a critical level. The exception is when the water drop is high in alkalinity (like high TDS ground water found in most cities in India) initially from pollution, hard water, or contaminants the process occurs extremely rapidly.

Step 3. As the water evaporates, the soda solution condenses and the pH level rises. When the pH level of this droplet reaches about 9, the

rate of corrosion accelerates rapidly. Microscopic channels form beneath the surface of the glass, whereby molecules in the water drop and the glass can exchange and bond. Over time, as more soda leaches out of the glass, the remaining silica network becomes honeycombed and highly porous, eventually destroying the structural integrity of the glass.

from within the glass structure. If it were possible to keep glass clean and dry at all times (or even just squeegee off the water immediately after wetting), glass would stay in clear condition for a long time. If one cannot keep glass in a temperature-controlled environment and continually squeegee off the glass so that water never dries on the surface when it gets wet, one will eventually have to deal with glass corrosion. Alternately, glass surfaces can be sealed with Diamon-Fusion®, which lets the nano-chemical-treatment process form an invisible barrier between glass and water.

Should we wait till glass is corroded to apply DiamonFusion®?

Step 4. When the water drop has evaporated (repeatedly), it leaves behind a deposit of soda (and other chemicals) firmly bonded to the glass surface. This is the most noticeable visual effect of glass corrosion — a “foggy” or “cloudy” appearance. One may also notice in areas where acid rain is a problem that glass will have streaks caused by the acidic rain partially dissolving the soda deposits as it runs down the surface of the glass. These deposits and streaks resist normal cleaning methods, and if cleared (using specially formulated acidic agents) they will quickly return in the exact locations since the corrosion channels are already established. That is why it is critical to seal the glass from contact with water and not just “clean” off the appearance of fogginess.

No, that is not the wisest thing to do. It is because while sealing glass with Diamon-Fusion® will stop the corrosion process, it cannot repair the damage already done, nothing can. So, don’t delay – Diamon- Fusion® glass today! Users will gain many other benefits as well, including hydrophobic (water beads up and sheds quickly, improving visibility), oleophobic (resists petroleum-based film from exhaust from attaching to the glass), glare reduction (improves night vision), scratch and impact resistant (up to 10 times stronger than untreated glass) and makes removing graffiti, smudges, finger prints much easier.

It is obvious from above that cleaning glass with either hard or soft water will aggravate this problem; cleaning your glass with “purified water” will simply allow the water to absorb more soda and other chemicals

from passing the glass, giving it an edge over other windows material options. The U-value which is a measure of the rate of heat loss is expressed in watts per square metre, per degree Kelvin. Lower U-values can be attained if there is a use of multiple glazing layers, gases, and low e-coating. Steel Reinforced: These windows are fitted with galvanised steel reinforcement so it does not bend easily and is very stable to use in uPVC windows and doors. Double Seals an added advantage: The double seals used in the uPVC windows help to keep rainwater outside as much as possible while sealing the glass pane against the uPVC Window. And that’s not all, in areas where one may experience a lot of dust, these windows can help prevent dust from entering. Colour Palette: If you think there is just one colour, you are wrong. uPVC windows are available in a number of hues like Mahogany, Dark Oak, Golden Oak, Rustic Oak, Walnut to name a few. These have a finish and look of

wood from a distance. So if you are a lover of wood, you won’t miss it at all. Perfect colour coordination can now be done with the variety of colours one can choose from. Low on Maintenance: uPVC windows do not need regular cleaning or maintenance. It is once in a lifetime investment. uPVC windows also help in energy saving and so it keeps your electric bills in check. Multi-Locking System: A home has to also be safe and secure for the people living in it. uPVC Windows have a multi–locking facility which is an added advantage. uPVC Windows and doors will help reduce the heat coming from outside, keep the place cool, and will help

reduce electricity bill. uPVC windows are value for your money and so it is recommended one opts for this to add beauty and panache to their homes.
