ARC Rockfibre Insulated DPC

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 brick or block. 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.   

ARC Rockfibre Insulated DPC has been fire tested at Warrington Fire Research, achieving up to four hours fire integrity with traditional masonry brick and block construction. 

No CFCs or HCFCs are involved in the manufacturing process of ARC’s rockfibre mineral wool insulation. The material presents no known threat to the environment and is classed as ODP and GWP zero.
