A door sweep is a seal affixed to the base of a door to prevent air, water, insects, and debris from entering a building. Typically made of rubber, silicone, felt, or similar materials, these seals play a vital role in maintaining comfortable indoor temperatures and protecting against drafts.
Effective sealing at a doorway’s threshold minimizes energy loss by reducing the transfer of heated or cooled air between indoors and outdoors. This leads to lower energy bills and a smaller carbon footprint. Furthermore, a properly sealed entryway offers protection against moisture intrusion, reducing the risk of mold growth and structural damage. Historically, simple materials like fabric and rope were used for this purpose, but modern advancements have led to more durable and effective solutions designed for specific climates and door types.
