The ARC Masonry Party Wall System is an innovative fire-stopping solution for masonry constructions with an adjoining party wall. The System is comprised of nine complimenting products all designed to halt the spread of smoke and flames within hidden cavities at the party wall.
Aside from the life saving fire-stopping capabilities, the masonry System provides an impressive reduction in potential heat loss. The ARC Masonry Party Wall System dramatically reduces heat loss along the edges of the party wall, enabling a great 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. The Masonry Party Wall System directly addresses heat loss, supporting a high EPC rating and lowering energy bills.
