Why Drafty Windows Are Costing You Money

A drafty window is not just a comfort problem. It is a leak in the building envelope, which means the air you paid to heat or cool is escaping and outside air is getting in.

Most homeowners notice the problem first on a windy day or during the first cold snap. You feel a chill near the frame, the room never quite warms up, and the thermostat seems to run constantly.

What A Drafty Window Is Really Doing To Your Home

Air leakage around a window creates a chain reaction. Conditioned air escapes, outside air enters, and your heating or cooling system keeps cycling to compensate.
