How does it work?

A transparent coating on the outside of the glass harnesses the power of both sun and rain to efficiently

remove dirt and grime.

Exposure to UV rays from the sun triggers the decomposition of organic dirt and prevents mineral dirt from

adhering to the surface of the glass. It also turns it “hydrophilic” – implying that when it rains, the water

sheets across the glass without forming droplets, and rinsing away the broken down residue.

Only a small amount of sunlight is required to activate the coating, and so the self-cleaning function works

even on cloudy days.

Benefits

Self-cleaning glass does not need cleaning as frequently as ordinary glass does. However, it is not 100%

maintenance-free. A simple rinse with water during dry spells is required to aid the cleaning process. This

glass keeps clean by using natural elements present in UV rays and rain.

Requires less frequent cleaning

Saves money

Ideal for glazing hard-to-reach areas, such as roofsProvides a permanent coating – lasts as long as the window does

Is eco-friendly by virtue of using natural elements for cleaning, rather than detergents and other cleansers

Self-cleaning glass can be combined with other glass products for multi-functional glazing, such as thermal

and solar insulation glass, acoustic glass and safety glass.

Self-cleaning glass

Normal glass and SGG BIOCLEAN

Normal Glass : Accumulation of grime and

dirty water marks.

BIOCLEAN - Action 1 : photocatalysis

Exposure to the UV rays in daylight triggers thedecomposition of organic dirt and causes the

surface of the glass to turn hydrophilic.

Action 2 : hydrophilic action

Water (or rain) forms a sheet of water acrossthe surface of the glass and rinses away

broken-down organic dirt and mineral material



Reflective Glass

Glass that keeps the heat out!

Solar control glass/Sun Ban Glass controls the entry of solar heat into a building,

thus preventing interiors from heating up excessively. In this way,solar control glass

promotes energy-efficiency by reducing the load on air conditioning, even as it

obstructs visibility from the outside

How does it work?Solar control glass has a microscopically thin coating on its surface. This coating is made up of metal or metal oxides, and is comprised of a single or

multiple layers. It is this coating that cuts out the sun's heat. While keeping the building interiors cool, Sun Ban glass also ensures optimum light

penetration, thus minimizing dependence on artificial lighting during the day.

Benefits

Solar control glass can be used extensively for façade glazing, as also for windows glazing, curtain walling, bolted glass assemblies and glass

greenhouse roofs. The benefits of using this glass are several:

Enhanced comfort: By controlling the penetration of the sun's heat into a building, Sun Ban glass makes for cooler and more comfortable interiors.

Energy efficient cooling: A naturally cooler interior space automatically reduces the need for air conditioning, thereby saving on energy costs.

Energy efficient lighting: Sun Ban helps save energy not just through reduced air conditioning, but also through reduced artificial lighting – this glass

ensures that sufficient daylight enters the building.

Privacy: Obstructs visibility from the outside, thus protecting the privacy of the occupants.

Aesthetics: Sun Ban is not just about functionality. The various colours it is available in impart unmatched visual appeal and brilliance to a building.

Solar control glass can be combined with several other glass products for multi-functionalglazing, such as with thermal control glass for low emissivity,

glass for acoustic insulation, decorative glass for aesthetics and even safety glass.

Green BuildingsEnergy-efficiency is, unarguably, the most important criterion for classifying an architectural structure as a ‘green building’. Energy-efficiency could

entail reduced dependence on artificial lighting by maximising the use of daylight, or minimising the need for air conditioning or heating, as the case may

be.

Saint-Gobain's glass products provide these very functionalities, thus being almost indispensable to modern green buildings. A comfortable internal

environment is known to substantially improve the work productivity and health of the occupants of a building.

Here are some examples of how Saint-Gobain’s energy-efficient glass has been applied to commercial buildings.

• ITC

• WIPRO





Transparent, translucent and opaque glass

Transparent or clear glass makes the best use of natural light, while controlled light

transmission by translucent glass assures occupants' privacy. Opaque glass, on the other

hand, obstructs light completely, assuring not just privacy but also imparting good aesthetics.

How does it work?Clear glass is the base material on which all kinds of glass are manufactured. They can be

made in different thicknesses, depending on the requirement of the application.

Benefits

Saint-Gobain’s clear glass is known for its immaculate clarity, making it ideal for transparent

partition where transparency is required.

Translucent and opaque glasses provide privacy, safety, comfort and aesthetics.

Low-e, energy efficient glass

Thermal insulated glassensures warmth within abuilding during winter by preventing the heat inside,

generated through artificial means, from escaping to the outside. This reduces the pressure on the heat

source and substantially improves theenergy efficiencyof your living space.

How does it work?

Thermal insulated glass has a microscopically thin and transparent metallic coating that reflects long-wave

heat radiation. This helps in retaining heat within a building during winter, while optimizing light

transmission.Benefits

Using thermal insulated glass in combination with solar control glass in a double glazedunit is the best

way to maximise the energy efficiency of windows and facades, making your living space very

comfortable.

Thermal insulation: Regulates heat gain/loss, making for an optimally comfortable living space.

Optimal light transmission: Allows sufficient daylight to enter the interiors.

Energy efficiency: A reduced need for artificial heating /cooling helps cut power costs and protects

the environment.
