ClimaGuard® Residential Glass

ClimaGuard Neutral 70

Mother brings a dish of meal at table to her hungry family.

Durability and efficiency for doors and specialty applications

ClimaGuard® Neutral 70 represents a new standard in durable high performance low-E glass. Designed for use in light commercial and residential applications, Neutral 70 provides the optical clarity and energy performance traditionally associated with sputter coatings. It also has handling and fabrication characteristics comparable in most respects to pyrolytic coatings. Neutral 70 is the perfect solution for doors and wear-and-tear applications, such as between-the-glass blinds.

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.
