The Type E is a preformed DPC cavitray which is inserted into an existing cavity wall. The Type E requires only one course of bricks to be disturbed, with just a few bricks removed at any time. The self-contained Type E cavitrays are the length of two bricks, and clip together, so long runs are easily and quickly created. Preformed angles cater for corners and piers. Each unit has stand-alone discharge via a weep. Suitable for all popular cavity widths because the cavity upstand of the Type E is hinged and adjusts to always suit the ‘as-found’ cavity width. Cavitray for insertion into an existing wall. Properties Length: 450mm. Widths accommodated: 50mm to 140mm. Thermal transmission: 0.15 to 0.17. Material: polypropylene DPC. Colour: black. ODP: zero.
