Glass Specifications for Energy Efficiency
In our climate, most of the unwanted heat comes straight through the glazing, not around it.
Choose low-E glass that resists radiant heat, focusing on a low SHGC and a U-factor that still reins in conductive transfer.
Commonly, you are looking at dual-pane, argon-filled units with low-E coatings and warm-edge spacers to curb conductive losses at the edges.
If you have big west or south exposures, add an additional low-E layer or a slight tint to manage late-day spikes, but avoid dark tints that kill natural light.
