Provides the optical clarity normally associated with sputtered coatings
SunGuard® High Durable
Silver Grey 32
SunGuard® High Durable (HD) glass is a high durability sputter coated solar control glass. The product provides all the optical clarity and energy performance that is traditionally associated with sputtered coatings. The durable coating is based on highly resistant materials that enable the glass to be used monolithically, when applied on the inside surface (#2). The handling and fabrication characteristics are comparable to any other product available for monolithic glass applications.Typical applications include the outer glass of double skin facades, ventilated glazing, spandrel panels, glass louvres and external shading fins for solar control shading purposes.

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.
