Even though your doors and windows are shut to keep cold outside, there’s still a chance that some of your heat is escaping through gaps underneath a door or spaces along a window sill. Even small gaps can release a surprising amount of heat while letting unwelcome cold air inside. 

Draft stoppers block those gaps with filled tubing that lies at the bottom of the door or window. Vinyl stoppers that attach to the door or window also are excellent ways to keep the cold at bay. They are affordable and easy to install, and can save you from shivering and paying more on your utility bill.  

In this article: Decorealm Draft Stopper, Evelots Draft Stopper and Twin Draft Guard Extreme Door Stopper.

How much heat are you losing?

It’s tempting to see a small gap under your door or window and think that there probably isn’t a lot of heat being lost. But according to the U.S. Department of Energy, air leaks around windows can lead to 30% heat loss, and air leaks around doors contribute to 20%. Just an 8-inch gap loses as much heat as if there were a 2.5-inch hole in the wall. Check your doors and windows closely and note any gaps that need sealed off before winter really gets going. 

Draft stoppers are easy to attach

One of the most important features of door draft stoppers is that they attach to the door. You no longer have to put them in place when you get home and hope that some of the gap is covered when you leave.

Most draft stoppers attach one of two ways. They either attach under the door with the stopper cushioned on the outside, or they come with clips or magnets to adhere to the door’s base. Either way, the stopper slides with the door as it opens and shuts. Most stoppers are made from materials that easily slide with most flooring types. Once attached, you don’t have to worry about the stopper again.

A good fit is the best way to keep cold air out

Most draft stoppers are 36 inches long, which is the width of a traditional door. Not everyone has a traditional door, though. Measure the doors and windows that need the draft stopper to make sure you have the right size. If you draft stopper leaves a gap around a door or window, you are still losing heat.

Many draft stoppers are flexible and can be wrapped around the door to ensure full coverage. Other stoppers, such as vinyl seals, can be cut with a saw to fit your door perfectly and ensure that the heat stays inside. 

Some draft stoppers match your decor

While being practical, there’s no reason that your draft stoppers can’t be stylish, too. There are still traditional white and brown draft stoppers that generically blend in with most rooms,  but many now come in a variety of colors and patterns that can fit a wide range of decors. A few manufacturers have even designed stoppers that look like animals. These fun designs are great for pet lovers or as conversation pieces.
