Clear Glass with UV Package

Looking for glass specifically designed to protect your possessions from fading while keeping your home cooler in the summer? Our UV glass package is right for you.

Cooler in the Summer

The SHGC (Solar Heat Gain Coefficient) for DLA-UV is 66% better than clear glass and 30% better than DLA giving you a cooler summer.

What is SHGC?

SHGC is a measurement of how much of the sun's heat is transmitted through the window or door. It is best described in terms of a ratio; where 1 is the maximum solar heat gain that comes through a window and 0 is the minimum. A window that has a SHGC of .3 will allow 30 percent of the sun's heat to pass through.

Increased Fade Protection

The DWT (Damage Weighted Transmittance) for DLA-UV 43% better than clear glass and 23% better than DLA.

What is DWT?

DWT is calculated according to a function called Tdw-ISO, developed by the International Standards Organization and published by the International Commission on Illumination (CIE), the world's leading technical organization on light and illumination. The Tdw-ISO calculation measures fading risk from solar radiation across the entire solar light spectrum, from Ultra-Violet light through visible light. According to the CIE standard, which is considered more comprehensive than Ultra-Violet rating alone, our UV glass packages can minimize fading damage across the entire solar spectrum more effectively than glass designed primarily to block Ultra-Violet light.

All calculations based on 7/8" thick, double glazed, single strength IG units using NFRC (National Fenestration Rating Council) methodology with Lawrence Berkeley National Laboratory's Windows 5.2 software.

NFRC is a non-profit, public/private organization created by the window, door and skylight industry. NFRC's primary goal is to provide accurate information to measure and compare the energy performance of window, door or skylight systems.
