ClimaGuard® Residential Glass Innovation

ClimaGuard IS-20

Boost window performance to meet energy codes

An add-on interior coating to the fourth surface, ClimaGuard IS-20 coated residential glass helps prevent heat loss in the north and reduce cooling costs in the south for ideal energy savings. This coating is durable and easy to maintain, making it an excellent choice for high-exposure applications like monolithic storm windows.

Key features:

A breeze to maintain: As easy to clean as ordinary, uncoated glass
Long-lasting coating: Mechanically and chemically durable, as scratch-resistant as the glass
Easy to fabricate: Single product for annealed or tempered applications

The thermal stress guideline is only a rough guide to the thermal safety of a glazing. Other factors such as large glass areas, shapes and patterns, thick glass, glass damaged during shipping, handling or installation, orientation of the building, exterior shading, overhangs/fins that reduce wind speed, and areas with high daily temperature fluctuations can all increase the probability of thermal breakage. The results shown are not for any specific glazing installation and do not constitute a warranty against glass breakage.
