Saint-Gobain Glass and Glazing

Glass Technology for Sustainable Habitat

Saint-Gobain Glass and Glazing offers a complete range of energy-efficient coated glass and insulated glazing. With solar control, low emissivity, low maintenance, and transparency, our glass meets the requirements of low energy consumption buildings.

The technology behind solar control and low emissivity is a thin transparent coating of metallic oxides, deposited on one or two glass panes of a double or triple glazing unit. An invisible thermal shield, this coating retains the heat inside the building and captures the sun heat to keep it outside. The innovation and the technology developed by Saint-Gobain serve to create well-being for sustainable habitat. Brochure ›

Key Glazing Performance Factors

SHGC/g-value – Total solar energy entering into the building. Value between 0 and 1. The lower the g-value, the more efficient the glazing is in blocking solar entry.

LSG: Light to Solar – Gain (selectivity) Ratio between the visible light transmittance (VLT) and the Solar Heat Gain Coefficient (SHGC). The higher the LSG, the better the glazing is in reducing more solar energy than visible light.

U-value -Thermal Transfer Coefficient. Quantity of heat transmitted through the glazing due to the temperature difference between inside and outside. The lower the U-value, the better the thermal insulation performance.

Shading Coefficient – (SC) SC = SHGC/0.87
