Passive House performance,
and so much more

Guardian ClimaGuard®nrG is a powerful insulating glass configured using a combination of Guardian ClimaGuard®nrG and Guardian ExtraClear®float glass to create triple glazed insulating units that provide outstanding neutral aesthetic and exceptional thermal insulation. The high level of light transmission combined with neutral and low glass reflection make the aesthetics of your triple glazed units comparable to that of an ordinary double glazed insulation unit. Guardian ClimaGuard®nrG provides powerful insulation against harsh winters as it selectively invites sunshine into the home as a free and sustainable heat source, offering the ideal balance between low U-value, high transparency, colour neutrality and solar heat gain.

Exceptional thermal insulation

Minimises heat loss to maintain desirable inside temperatures

Passive House component

Harnesses passive solar heat, certified by Dr. Wolfgang Feist of the Passivhaus Institute

Visual performance

Neutrality and clarity similar to an ordinary double-glazed unit

Heat-treatable version

ClimaGuard nrGT (tempered version) offers maximum flexibility

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.
