Sealing accessories
Description
A supple membrane in a roll based on PVC treated against ultraviolet light, which makes it possible to form a valley in a single piece whatever the angle formed by the two slopes. Raised ribs channel the water and keep it from running back sideways, which improves drainage and rules out the risk of water ingress under the covering. The product suits new build as well as renovation. Installation means running the valley out along the centre line, covering it by about fifteen centimetres with the covering elements, then cutting it at the head and the foot so that the water is properly carried back into the gutter. It is fixed with large-head nails spaced at most 20 cm apart, in the side channels provided, the top being sealed with the ridge closures. Rolls of 25 m, width 475 mm.
