Door frame seal strips are materials installed around door frames to fill gaps between the door and the frame, preventing drafts, dust, noise, and moisture from entering a space. These seals come in various materials, including rubber, foam, and silicone, and are designed for different applications, whether for residential homes or large commercial buildings. The primary function of these strips is to create a tight seal that enhances energy efficiency by minimizing heat loss or gain, ultimately reducing utility bills.
