Advanced solar control glass

Saint-Gobain Building Glass has added to its SGG Cool-Lite Xtreme solar control range for the commercial glazing market.

SGG Cool-Lite Xtreme 50/22 II is a high-quality solar control glass. With a selectivity of 2.24, SGG Cool-Lite Xtreme 50/22 II enables designers and specifiers to create comfortable working environments with high levels of natural daylight but without the overbearing heat of the sun. It also reduces the need for costly and energy-hungry air conditioning systems and can therefore reduce a building’s carbon footprint.

The product delivers a high light transmittance (47%) to allow a good amount of natural daylight to illuminate a room, combined with an extremely low solar factor of only 0.21, which blocks 79% of the sun’s heat. It also delivers a low centre pane thermal insulation of 1.0W/m2K, maximising heat retention within the building.

Incorporating SGG Cool-Lite Xtreme 50/22 II in a commercial building can contribute towards a building’s BREEAM points and boost the overall BREEAM rating.

Exhibition Centre Liverpool is the first UK project to fully use the high-performance coating and features the product across the full length of its glass facade.  

Saint-Gobain building glass Commercial market manager Adrian Adams said: ‘’SGG Cool-Lite Xtreme 50/22 II is a fantastic addition to our range of solar control products. The coating has a good level of neutrality and low external reflectance, giving the glass excellent aesthetics.

“This new product provides architects with another tool in their design armoury to produce striking facades for their clients without compromising on high performance solar control protection.

“We believe that we have pushed the boundaries again with the product’s market leading selectivity and are sure it will have a substantial impact on the architectural concept and design of the facade due to the fact that architects may not have to work with external shading devices.”
