ClimaGuard® Residential Glass

ClimaGuard Solar

Intelligent solar control for windows, even large ones

Ideal for renovation projects or new residential builds, Guardian ClimaGuard® Solar coated glass combines a high level of thermal insulation with effective solar protection for windows. Its reduced solar factor minimises air conditioning costs and contributes to an optimal indoor environment all year round. In the winter, its powerful insulation keeps warmth inside. In the summer, it keeps air conditioned spaces cool, both by insulating and selectively reflecting unwanted solar heat, while it permits natural daylight to enter. Guardian ClimaGuard® Solar glass is beautifully transparent, giving designers and builders the freedom to use larger windows, flooding home interiors with natural daylight.

Displayed colors are intended to represent actual color. Color is a function of light and reflectivity and cannot be accurately portrayed online. Actual glass samples should be used to determine color. Please order a sample and discuss color with your Guardian Architectural Design Manager to ensure you are pleased with your SunGuard selection before ordering glass for your project.

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.
