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.
