If you live in northern Arizona, your garage probably gets mighty cold during the winter. Its entrance is, after all, the largest opening on your home.
So when the door goes up and down, any warm air gushes outside. And even when the door is closed, cold outdoor air seeps in.
Keep the garage warm in the winter by installing a weather seal between the bottom of the garage door and the garage floor. If you can see through the gap between the door and the floor, it’s time to replace the stop.
Better yet: Replace your old garage door with an insulated model, which can keep an unheated garage 10 to 20 degrees warmer during the winter than an uninsulated door.
The warmer you keep your attached garage during the winter, the less cold air will seep into the living spaces next to and on top of it.
A well-insulated door can help keep your unheated garage 10 to 20 degrees warmer on a cold winter day, according to manufacturer Clopay.
Buy an insulated garage door before the end of 2010—and install it on a garage whose outdoor walls also are insulated—and you could qualify for a tax credit worth 30 percent of the purchase price, up to $1,500. Your garage door dealer will know which models qualify for the tax credit, and will give you a certificate that verifies you have bought an eligible door.
