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 provdes an effective edge seal around the party wall cavity, helping to achieve a zero U-value.

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.

Key features:

• Up to four hours fire integrity.
• Seals edge of party wall cavity.
• Up to three times more effective as an edge seal than conventional systems.
• Reduces flanking noise.
• Zero U-value at party wall can be achieved.
• Minimises thermal bypass.
• Easy to install.
• Available in different size.
• Green Guide rating of A+.
