ARC T-Barrier and Pitched Roof System - Timber Frame
Fire barrier for cavity walls and roof
The ARC T-Barrier system has been developed to create an effective edge seal around the party wall cavity and to provide a complete fire barrier between two dwellings, both in the vertical cavity and the cavity between the pitched roofs within a timber frame construction.
Benefits
- Zero U-value at party wall can be achieved
- Up to three times more effective as an edge seal than conventional systems
- Simplified installation when compared to conventional systems
- Reduces sound transmission between the dwellings and within the cavity
- Minimises thermal bypass
The ARC T-Barrier provides up to 1 hour fire integrity in timber frame construction, and meets the Robust Detail's requirement for a barrier where a separating party wall meets an external cavity wall, significantly reducing sound transmission across the cavity. It also satisfies NHBC Chapter 7.2 D13 'Junctions between roofs and compartments or separating walls adequately resist fire spread.'
