The flat roof base elements have diverse benefits and are used, e.g. to lead through ventilation ducts, drainage or other penetrations on the roof.
With the FLECK flat roof base elements with backflow seal there is no need to bond the inserted rigid PVC pipes of extensions (plumbing vents, goosenecks, drains and gullies) – and you therefore also save the investment in the adhesive.
The nominal sizes DN 70 – DN 150 of the FLECK base elements are supplied with precise-fitting integrated lip seals. This makes installation of the extensions far easier, improves handling on site and reduces installation errors. The flanges of the flat roof base elements are made of high-quality rigid PVC and have predrilled screw holes for fixing.
FLECK products are designed to be compatible with each other and thus mutually optimise their respective performance. This is not only practical but also saves the installer valuable time.
The flat roof base elements have diverse benefits. They are used to lead through ventilation ducts, drainage and other penetrations on the roof. The FLECK base elements are one-piece and have a stable flange made of rigid PVC and, if necessary, a flange collar made of bituminous membrane. A proper vapour-tight joint on the vapour barrier made of plastic sheeting or bitumen sheet can therefore be achieved effortlessly. Flat roof base elements form the precise-fitting base for extensions, roof drains, gullies, vents and goosenecks in the appropriate diameters.
