Conclusion

The main purpose of a draft stopper is to prevent warm air from escaping through gaps in doors and windows. By creating a barrier, draft stoppers help to reduce energy costs and keep homes warm during the winter months.

There are a variety of ways to make draft stoppers, but one of the most popular methods is to use an insulator. Insulators are materials that resist heat transfer, making them ideal for draft stoppers.

Common materials used for insulators include fiberglass, polystyrene, and polyurethane.

When choosing an insulator for your draft stopper, it is important to consider the climate in your area. For example, if you live in a cold climate, you will want to choose an insulator with a high R-value, which measures its ability to resist heat flow.

On the other hand, if you live in a warm climate, you may want to choose an insulator with a low R-value so that it can help keep your home cool in the summer months.

No matter what material you choose for your draft stopper, it is important to make sure that it fits snugly in the opening. Gaps around the draft stopper will defeat its purpose and allow warm air to escape.
