A compression seal is a flexible sealing material compressed between surfaces to prevent air, water, dust, or noise penetration.

A compression seal is a type of flexible gasket or sealing system designed to create a tight barrier when compressed between two building components. Commonly made from rubber, silicone, neoprene, or foam materials, compression seals are used to block air infiltration, water intrusion, dust, and sound at joints and openings.

In construction applications, compression seals are frequently installed around doors, windows, panels, and expansion joints. When the adjoining surfaces come together, the seal compresses to fill gaps and irregularities, maintaining a continuous barrier even with minor movement or tolerances. This makes compression seals especially effective in areas subject to vibration, thermal expansion, or frequent use.

From a performance standpoint, compression seals contribute to building envelope integrity, energy efficiency, and occupant comfort. Proper material selection, sizing, and installation are essential to ensure long-term durability and consistent sealing pressure. In commercial and industrial settings, compression seals are often specified to meet fire, acoustic, or weather-resistance standards.

Compression seals are widely used in clean rooms and laboratories, where maintaining airtight and contaminant-free environments is critical.
