External wall cavities: The ARC Party Wall Cavity Stop Sock is designed to enhance fire safety within external wall cavities by providing an effective barrier that prevents the spread of fire and smoke. Positioned in line with separating walls or floors, it also aids in maintaining thermal insulation by reducing heat transfer at critical junctions, which supports the building's energy efficiency. The Stop Sock is easy to install, typically fitting snugly within the cavity without the need for additional fixings, and offers moisture resistance to protect the internal structure from potential water damage. Additionally, it meets building regulations for both fire safety and thermal performance.
