Sealing strips are materials used to close gaps and seams around doors, windows, and other openings. They are designed to act as a barrier against air infiltration, dust, moisture, and even noise. Typically made from rubber, foam, or silicone, sealing strips come in various sizes, shapes, and thicknesses to cater to specific needs. The primary function of these strips is to create a tight seal that prevents air from escaping or entering, leading to enhanced energy efficiency.
