The ARC T-BarrierĀ® Pitched Roof is easily installed once the party wall blockwork is complete, with the unique T-shape being held in place by compression between the two leaves of party wall blockwork. Care should be taken when handling the product to ensure that the mineral wool isnā€™t damaged.

FAQ’s

Can this product be used with a flat roof?

Yes, ARC T-BarrierĀ® Pitched Roof can be used with either a pitched or flat roof, provided there is a party wall with a cavity, and a 25mm gap between the top of the wall and underside of the roof.

Do I take it out of the coloured sleeve?

The polythene sleeve is there to provide product identification and protection from the elements and should therefore be left in place. It does not add to the performance of the product so can be safely cut into, and the product can still be used should the polythene be damaged.

Can this cover multiple cavity sizes?

The ARC T-BarriersĀ® are designed to suit specific cavity widths and are available in 5mm increments. Itā€™s important that the appropriate size is fitted to achieve the required compression fit and to ensure the product performs as expected.

Do you have further documentation for the ARC T-BarrierĀ® Pitched Roof?
