In buildings constructed of cavity Walls, whenever there is a window or door opening it is necessary to close the cavity. The traditional manner involved turning the internal skin through 90 degrees and incorporating a DPC to prevent actual physical connection with the damp mortar and masonry of the outside skin. A flexible vertical DPC can be easily damaged or misplaced, The Type D DPC overcomes such problems and speeds up operations on site. The Type D is insulated and automatically introduces a thermal break within the reveal. The Type D offers flexibility and self-supporting rigidity, whilst protecting the masonry return completely.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Cavity Trays is consulted before specifying.
