ARC Rockfibre Insulated DPC is designed to fire stop the gap between a return block and external brickwork, and can be manufactured to suit any width up to 50mm. For larger width see ARC Eco-Closer.
ARC Rockfibre Insulated DPC is a fire rated cavity closer designed to close the cavity around window and door reveals in conjunction with a return block, fitting between the return block and inner edge of the outer skin of brickwork. The rockfibre insulation will help prevent cold bridging and eliminate moisture, mould and staining from around windows and doors, while the DPC is embossed to assist mortar adhesion. It must be installed with a minimum of 5mm compression to achieve 2 hrs fire integrity, or a minimum of 15mm compression to achieve 4 hrs fire integrity.
