This is an assessment of Arc T-Barrier for timber frame construction. Its function is to provide an effective edge seal around the party wall cavity and to provide a complete fire barrier between the two dwellings, both in the vertical cavity and the cavity between the pitched roofs. By creating an effective edge seal around the party wall cavity, the ARC T-Barrier System helps to achieve a zero U-value at the party wall.
