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.

• Up to four hours fire integrity


• Seals edge of party wall cavity


• Zero U-Value at party wall can be achieved


• Up to three times more effective as an edge seal than conventional systems


• Reduces flanking noise


• Minimises thermal bypass


• Easy to install
