We think of our homes as refuges from the outdoors. Sequestered away from the wildfire smoke and the pollution outside, we tailor our indoor environments right down to the degree as if we were all weather forecasters with magic wands. But homes leak an incredible amount of air. All that expensive heating you pay for during fall and winter mingles with the cold air continuously spilling in through windows, doors, floors, and electrical sockets. Buildings—even new ones—are a lot draftier than one would expect, and the volume of cold winter air that can seep through the tiniest crack or pinhole is mind-bogglingly significant. There are ways to mitigate it with a few quick fixes. Take a cursory look around your place to find the cold spots in your home before you drop money on a thermal leak detector. You can get an idea if there are gaps in your door frames and baseboards and if you can feel the cold air rushing in through the weather stripping around your windows. We've outlined several things you can do to insulate your home and keep the hot air in this winter. These are all approachable projects anyone can tackle, and none of them costs much money. With the savings to your utility bill, they might even pay for themselves. |
