Seals applied around the frames of exterior doors in manufactured housing prevent air and moisture infiltration. These flexible materials, typically made of rubber, foam, felt, or vinyl, fill gaps between the door and its frame, creating a barrier against drafts, leaks, and pests. An example includes adhesive-backed foam tape applied to the door jamb.
Effective sealing significantly improves energy efficiency by reducing heating and cooling loss, leading to lower utility bills and a smaller carbon footprint. It also enhances comfort by eliminating drafts and maintaining a consistent indoor temperature. Furthermore, it protects against moisture damage that can lead to mold growth and structural deterioration. Historically, simple felt strips were common, but advancements in materials science have resulted in more durable and effective options, like silicone and EPDM rubber. These modern materials offer superior resistance to weathering and temperature extremes.
