ARC T-Barrier Foundation for 100mm Party Wall Cavity - Fire Barrier for Party Wall Junctions at Foundation Level - Pack of 12

ARC T-Barrier Foundation for 100mm Party Wall Cavity is a non-combustible rockfibre mineral wool cavity fire barrier that enables the closing of an external cavity at party wall junctions at foundation level receiving up to 4 hours fire integrity. ARC T-Barrier can be installed as the masonry work progresses, requiring only a friction fit within the cavity. Accuracy of masonry work is essential to ensure no gaps exist around the barrier. ARC T-Barrier is used where building regulations require the use of a mineral wool closer for acoustic insulation purposes. It provides an effective edge seal around the party wall cavity, helping to achieve a zero U-value.

Dimensions: a/b x c/d x length: 110mm/100mm x 105mm/250mm x 600mm
