When a roofline intersects with a concave or convex cavity wall it presents the designer with a problem. How best to externally flash and protect the structure against wet penetration? Cavity Trays of Yeovil now manufactures curved cavitrays that could offer a ready-to-use solution. The dimension of each tray is individually and compositely computer calculated to take into account the arc of the wall and the masonry coursing. Curved cavitrays can be supplied with the lead flashing already attached. Flashing dimensions are calculated to provide optimum weathering, deflection and overlap protection. Within the masonary wall the cavity is protected by self-adjusting cavity upstand flaps that can take up the cavity width encountered.

By using preformed trays and flashings, added living space can be obtained in ground floor rooms, claims Cavity Trays. By setting feature window frames forward of the masonry line, the living area is increased. Preformed Type G trays provide the dpc integrity within the wall, with a projecting code 4 flashing to dress over the roof covering up stand.
