Cavity fire barrier for masonry party wall junctions.
For masonry party wall junctions.
The ARC T-Barrier® achieves a zero U-value at the party wall junction by sealing the party wall cavity. This minimizes the effect of thermal bypass as well as reducing flanking noise in the cavity. The ARC T-Barrier® provides a four-hour fire integrity at the party wall junction and meets the Robust Detail's requirement for a barrier where a separating party wall meets an external cavity wall, significantly reducing sound transmission along the cavity.
It is easily installed as the brick and blockwork progresses. No mechanical fixings are required; a friction fit within the external cavity and compression fit within the party wall cavity ensure that the barrier stays in place. For runs of more than 1.2 m, lengths of T-Barrier® should be butted tightly together, with care taken to ensure that there are no gaps.
