ARC T-Barrier

The ARC T-Barrier achieves a zero U-value at the party wall junction by sealing the party wall cavity. This minimises the effect of thermal bypass as well as reducing flanking noise in the cavity.

The ARC T-Barrier provides 4 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.
