The ARC Party Wall system dramatically reduces heat loss along the edges of the party wall, enabling a zero U-value to be achieved.
Without effective edge sealing, the party wall cavity allows heat to escape. The image (below) highlights the areas of heat loss in a row of terraced houses, of a particular note is the heat loss at the top of the junction where the party wall cavity meets the external cavity.
ARC Cavity Stop Sock restricts the spread of smoke and flames within the cavity of external masonry walls.Product details
The ARC T-Barrier is designed to provide a ﬁre, thermal and acoustic break at the junction between the external cavity and the party wall cavity.Product details
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
Designed to provide a fire, thermal and acoustic break at the party wall between the roof tiles and roof membrane.Product details
ARC Soffit Slab is designed to fill the void within the soffit, providing a fire, thermal and acoustic barrier between dwellings.Product details
ARC Spandrel Barrier seals the top of the party wall cavity, allowing a zero U-value to be achieved when used in conjunction with ARC T-Barrier vertically.Product details
ARC U-Barrier is compressed between the top of the spandrel panel and underside of the roof covering, creating a fire and thermal break.Product details
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.Product details
