Thermal insulation and
low-E
Excellent thermal insulation and solar control
ClimaGuard® Residential Glass
ClimaGuard A+
This ClimaGuard earns a perfect score
Typically used in windows, conservatories, structural glazing, facades and curtain walls, Guardian ClimaGuard® A+ is a new and improved thermal insulating glass for double and triple glazed insulating units that meets the highest performance requirements in terms of transparency and solar heat gain. This new and improved low emissivity (Low-E) glass maintains the same thermal performance but with an increased level of solar heat gain. Guardian ClimaGuard® A+ allows solar heat to pass through the glazing, which is then retained within the building by the low-E coated glass. This means a positive effect on your heating costs during winter months as well as improving comfort levels in your home.

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 ClimaGuard 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.
