A product designed to mitigate drafts entering a structure through the gap beneath an entryway is readily available at a prominent home improvement retailer. These devices, typically constructed from foam, rubber, or fabric, affix to the lower portion of doors, effectively sealing the opening and preventing the ingress of air. Examples include adjustable sweeps, flexible barriers, and specialized weather stripping offered in various lengths and materials to accommodate diverse door sizes and styles.
The utilization of such a draft-reducing item contributes significantly to energy conservation within a dwelling. By minimizing heat loss during colder seasons and preventing the entry of warm air during hotter periods, it aids in maintaining a consistent interior temperature. This can lead to decreased reliance on heating and cooling systems, resulting in lower utility bills. Furthermore, these products can also help to reduce noise pollution from exterior sources and prevent the entry of dust, insects, and other unwanted elements. The underlying concept has existed in various forms for many years, with earlier solutions often involving rolled-up textiles or makeshift barriers.
