Frame & Glass - Energy Impacts

GLASS choices greatly effect the window's SHGC, U-factor and other properties
-Spacers impact U-factors and condesation
-Argon gas improves U-factors but not SHGC
-Low-E coatings offer greatest benefits
FRAME material and design variations primarily impact the overall Window U-factor
-Vinyl, wood and thermally broken aluminum frames will improve the U-factor and reduce condensation
-Frame variations have little effect on SHGC
