The Cavity Trays Type E Standard Straight Remedial Cavitray is designed to introduce a horizontal damp proof course (DPC) at a roof intersection level in a situation where the outside wall becomes an inside wall in the building of an extension. 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 and 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. The positive jointing integral anticapil clip eliminates gluing, sticking or overlapping. The shape and depth of the projecting lip prevents discharge water permeating the bedding joint - an often overlooked consideration on exposed sites.
All work can be executed from outside the building, and the inner skin of masonry need not be disturbed. In situations where the Type E is replacing a failed DPC, a flashing may not be required, depending on the application.
The Type E Cavity Tray is a preformed DPC cavitray that is designed to be inserted into an existing cavity wall. The Type E only needs one course of bricks to be disrupted for successful installation, with just a few bricks removed at any time. The self-contained Type E cavitrays are two bricks long, and clip together, so long runs can be created fast and easily. Preformed angles cater for corners and piers and 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.
Application: To introduce a horizontal DPC at roof intersection level in an outside wall which has become an inside wall, by virtue of an extension being built.
Non-standard preformed cavity trays are available, Cavity Trays can design and manufacture bespoke requirements. Non-standard trays maybe required in areas of buildings where complicated junctions are encountered. Please contact Roof Giant with your drawings and quantity required.
