This type of seal, characterized by its distinctive profile, is typically made of rubber, silicone, or other flexible materials. It functions by fitting over the edge of a door, window, or other opening, creating a tight barrier against the elements. A common application is sealing the gap between a car door and the body of the vehicle.
Effective sealing against drafts, moisture, and pests is crucial for maintaining comfortable indoor environments and preserving the integrity of structures. Historically, various materials like felt and foam have been employed for this purpose. Advances in material science have led to more durable and effective solutions, including this particular profile design, which provides superior grip and conforms well to irregular surfaces. This contributes to energy efficiency by reducing air leakage and minimizing the strain on heating and cooling systems. It also helps to prevent water damage and insect infestations, protecting both the structure and its occupants.
