ARC Cavity Stop Sock 150mm

The 150mm ARC cavity stop sock is a passive fire protection product designed to limit the spread of fire and smoke within cavity wall constructions. It is intended for use in buildings where cavity fire stopping is required to support fire compartmentation in line with regulatory fire safety guidance.

This ARC cavity fire sock is suitable for installation within 150mm cavities in masonry and timber frame wall systems. Once installed, the sock compresses within the cavity to form a continuous fire barrier, helping to restrict airflow and reduce the potential for fire spread through concealed voids.

The product may be used in external cavity walls, party walls, and internal compartment walls as part of an overall fire strategy. ARC fire socks are commonly specified where effective cavity wall fire stopping is required to support compliance with building control requirements.

Each unit is supplied in a 1200mm length and sold individually, allowing accurate quantity specification. Quantity discounts are available for full pack purchases, supporting efficient installation on larger projects.

Correct sizing and installation are essential to ensure effective compression and fire performance. The 150mm ARC cavity stop sock provides a reliable solution for sealing cavity walls in regulated construction environments.
