Application

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.

In order to achieve a fire rating the closer must be installed with a 15mm compression fit.
