Fire product
ARC Cavity Stop Sock restricts the spread of smoke and flames within the cavity of external masonry walls.
Product details
Fire product
The ARC T-Barrier Pitched Roof is designed to provide a fire, thermal and acoustic barrier between the top of the party wall blockwork and the underslaters felt.
Product details
Fire product
ARC U-Barrier is compressed between the top of the spandrel panel and underside of the roof covering, creating a fire and thermal break.

Cold bridging product
The requirement for ARC Eaves Insulator elevated from the problem of heat loss through the roof membrane at the junction between the pitched roof and the top of the cavity wall.
