Understanding Energy Efficiency Ratings

How window specs translate to lower AC runtime in Mandeville For our heat and humidity, start by targeting a strong U-factor and an SHGC tuned for sun control, which depend on the low-E glass stack. A lower U-factor slows heat flow into the house, which keeps rooms cooler. The SHGC needs to be low enough to block solar gain, or the AC will fight the afternoon sun every day. Different low-E formulas control infrared energy more than visible light, so you keep daylight while cutting heat.

Cost Considerations for Window Installation
