Seals designed for large, industrial entryways prevent the infiltration of air, moisture, dust, and pests. These barriers, typically made of flexible materials like rubber, vinyl, or silicone, are affixed to the door frame and/or door panels to close gaps. An example would be a heavy-duty rubber gasket fitted around the perimeter of a loading dock door.
Effective sealing systems contribute significantly to energy efficiency by minimizing drafts and heat transfer. This results in lower heating and cooling costs, and a more stable interior environment. Furthermore, these systems protect stored goods from damage caused by the elements and reduce noise pollution. Historically, simpler methods like felt or brush-like materials were employed, but advancements in materials science have led to more durable and effective solutions.
