Metal threshold seals and similar components fitted to door frames create a barrier against the elements. These barriers protect interiors from drafts, moisture, and pests. They typically consist of thin, flexible metal strips, sometimes with rubber or vinyl inserts, designed to conform to the door’s movement and seal gaps when closed.
Effective sealing around entryways contributes significantly to energy efficiency by reducing heat transfer. This leads to lower energy bills and a smaller carbon footprint. Historically, felt and similar materials served this purpose, but modern materials offer improved durability and resistance to wear and tear. Well-maintained barriers also enhance sound insulation and improve indoor comfort.
