This type of seal typically consists of dense bristles attached to a backing strip, often aluminum or plastic. It’s designed to be affixed to the bottom of a door, creating a barrier against drafts, dust, insects, and moisture. A common example is the fuzzy strip found under many exterior doors.
Effective sealing of gaps around doors contributes significantly to energy efficiency by reducing air leakage, thus lowering heating and cooling costs. Beyond energy savings, it enhances indoor comfort by minimizing drafts and preventing the ingress of unwanted particles. Historically, simple methods like stuffing rags or felt into gaps served a similar purpose, highlighting a long-standing need for such solutions. Modern materials and designs offer superior performance and durability.
