Are Triple-pane Windows Worth It in the Mandeville, Louisiana Climate?

The Mechanics of Triple-pane Windows

The third lite introduces another barrier to heat, glare, and sound, plus it shifts the weight and balance of the sash and hinges.

The heavier sash of a triple-pane window needs sturdier hardware and square, supported openings or you will fight sticky operation later.

Energy Savings vs Our Cooling-dominant Climate
