Door sweeps designed for use on external doors, available at Home Depot, are elongated strips typically composed of rubber, vinyl, or brush materials. They are affixed to the bottom of a door’s interior surface to create a seal against the doorframe threshold. An example is a vinyl strip with an aluminum carrier, screwed onto the inside bottom edge of an entry door.
These components are critical for energy efficiency, preventing drafts and air leakage, thereby reducing heating and cooling costs. Furthermore, they act as a barrier against insects, dust, and moisture, contributing to a more comfortable and cleaner indoor environment. Historically, rudimentary forms of door seals have been used for centuries to protect dwellings from the elements; modern iterations offer improved materials and designs for enhanced performance.
