Fire-rated cavity closer for window and door reveals.
Closes cavity around window and door reveals.
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 rock fibre insulation helps to prevent cold bridging and eliminate moisture, mould and staining around windows and doors, while the DPC is embossed to assist mortar adhesion. To achieve a fire rating, the closer must be installed with a 15 mm compression fit.
It is easily installed as the brickwork progresses and before the window or door is fitted. The DPC sits against the inner side of the outer brickwork to prevent moisture penetration.
