ClimaGuard®
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 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 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.
