Thin strips of metal, typically aluminum or stainless steel, are often affixed to door frames to seal gaps and prevent infiltration of air, water, and pests. These metallic barriers offer a durable and effective solution for enhancing energy efficiency and protecting against the elements. They can be found on both exterior and interior doors in residential, commercial, and industrial settings.
Effective sealing around doorways minimizes energy loss by reducing drafts and heat transfer. This translates to lower heating and cooling costs and contributes to a more sustainable built environment. Furthermore, such barriers protect against moisture damage, which can lead to wood rot, mold growth, and structural deterioration. Historically, less durable materials like felt or foam were common, but advancements in metallurgy and manufacturing have led to the prevalence of longer-lasting, more resilient metal options.
