This particular sealant, characterized by its cross-sectional resemblance to the letter “D,” is typically composed of rubber, silicone, or foam. It functions by creating a tight seal between two surfaces, such as a door and its frame, or a window and its casing. A common application is sealing the gap at the bottom of a garage door.
Effective sealing against the elements contributes significantly to energy efficiency by reducing drafts and heat transfer. This, in turn, can lead to lower energy bills and a smaller carbon footprint. Furthermore, such seals play a vital role in soundproofing, preventing dust infiltration, and protecting against pest intrusion. The development of specialized seal profiles like this reflects an ongoing refinement in building practices, enhancing comfort and resource management.
