ARC TBM100/125 T-Barrier Masonry 100mm Cav 110/100x130/250x1.2m

Arc T-Barrier Masonry For 100mm Width Party Wall Cavity

ARC T-Barrier enables the closing of an external cavity at a party wall junction where building regulations require the use of a mineral wool closer for acoustic insulation purposes. Additionally, it provides an effective edge seal around the party wall cavity, helping to achieve a zero U-value

Installation

The ARC T-Barrier Masonry 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 the barrier stays in place. For runs of more than 1.2m, lengths of T-Barrier should be butted tightly together, with care taken to ensure there are no gaps

Fire Properties

ARC T-Barrier Masonry has been fire tested at Warrington Fire Research, achieving up to four hours fire integrity with traditional masonry brick and block construction. These tests comply with EN1366-4.

IFC certificate number: IFCC 1728

Standards

ARC T-Barrier is manufactured using rockfibre mineral wool which achieves a fire classification of Euroclass A1 as defined in BS EN 13501-1, and conforms to BS EN 13162 and EN16001 Energy Management Systems. The DPC is manufactured in accordance with BS 6515.

ARC’s rockfibre mineral wool insulation has a thermal conductivity of 0.037W/mK
