ARC Party Wall Systems specialise in products designed for party wall construction within masonry cavity walls. In many residential buildings, the external wall cavity continues across the junction between adjoining properties. If not correctly treated, this cavity can allow fire and smoke to travel between buildings.
ARC systems are designed to close or compartmentalise this cavity at the party wall location. By introducing a cavity barrier within the external wall cavity, the system helps maintain separation between neighbouring properties while still allowing the wall construction to function as intended.
ARC cavity barrier products are frequently used in terraced housing, semi-detached homes and apartment developments where cavity wall construction is common.

These products are normally installed within the external wall cavity at the party wall line so that the cavity does not continue uninterrupted between adjoining properties.
Party wall cavity barriers form part of the wider fire safety design of the building envelope. Specifications often consider:
Party wall systems are typically referenced within fire safety guidance such as Approved Document B for residential construction.
The ARC products we supply include party wall cavity stop systems designed to suit typical cavity widths used in residential construction. These products are usually installed during wall construction and positioned so they overlap the party wall location within the cavity.
ARC cavity barriers are commonly ordered alongside masonry materials such as bricks, blocks and insulation used within the external wall build-up.
