Enhance fire safety within external wall cavities: The ARC 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.

• What is an ARC Cavity Stop Sock? - The ARC Cavity Stop Sock is a fire and thermal barrier designed to prevent the spread of fire and smoke through cavity walls. It also reduces thermal bridging, enhancing the energy efficiency of buildings.
• How do you install the ARC Cavity Stop Sock? - The ARC Cavity Stop Sock is installed by friction fitting it tightly within the cavity of a wall, typically at party wall junctions or around openings. It should be positioned to fully fill the cavity space, ensuring there are no gaps that could compromise its effectiveness.
• Where can the ARC Cavity Stop Sock be used? - The ARC Cavity Stop Sock is suitable for use in both residential and commercial buildings. It is commonly used in cavity walls, especially at separating party walls, floor junctions, and around window and door openings.
