Protective barriers installed around the perimeters of steel entryways prevent air and water infiltration. These barriers are typically made of materials like rubber, silicone, foam, or felt, and are available in various forms, including adhesive-backed strips, compression seals, and door sweeps. An example is a foam strip applied to the door jamb where the door closes against it.
Effective perimeter seals significantly enhance energy efficiency by minimizing drafts and heat loss, leading to reduced energy consumption and lower utility bills. They also improve sound insulation, creating quieter interior spaces. Furthermore, these barriers protect against moisture damage, preventing rot, mold, and mildew growth, thus contributing to the longevity of the door and surrounding structure. The need for such protection increased with the rise of mass-produced housing and the subsequent demand for efficient, cost-effective sealing solutions.
