Use

Preformed DPC cavitray complete with an attached ready-shaped lead flashing to form a stepped cavity DPC and flashing at the abutment of a pitched roof with a cavity wall. The Type X is the only “high performance” classified cavitray for gable abutments, and offers the builder numerous benefits. Ideal for new-build applications.

Introduction

Every stepped and every staggered gable abutment must be so constructed to prevent rainwater and dampness from penetrating below the abutting roof line. This is because the external skin changes status below the roof line and becomes an internal skin. The system fulfils three basic requirements: 1 It prevents dampness from penetrating below the critical stepped roof line. 2 It externally weatherproofs and flashes the physical roof/masonry intersection. 3 It also prevents the inside skin from becoming damp. The high performance Type X cavitray speeds up operations on site and ensures a good and known quality of build. Type X trays are handed, to suit left hand slopes and right hand slopes. Every tray is a self-contained unit, with its own ready-shaped lead flashing attached. Select long leads to dress directly over tiles, or alternatively short leads to dress over the upstand of a secret gutter or soaker. Unlike other systems, the Type X has an adjustable cavity upstand so it always suits the actual cavity width and is therefore always compatible. Just bed in position and flush point as the external skin is raised. At a later date the lead flashing may be dressed.
