PDA Rectangular roof flashing
Description
PDA is an A-type rectangular roof flashing that allows ventilation systems to be routed through the roof plane.
Intended use
The PDA flashing allows ventilation installations to be routed through the roof plane. The PDA constitutes an element responsible for transferring the weight of the ventilation equipment mounted on the roof flashing through the roof structure.
Design
A-type PD roof flashings are fitted with rectangular 20, 30 or 40 mm width flange connections (depending on the flashing size). Upon request, the holes for screws in the roof flashing flanges, can be made according to the individual guidelines. Atype PD units are normally made of zinc-plated steel of average thickness of the zinc coating equal to 19 micrometres.
Other external RAL colour-painted versions and a stainless steel customised version are available upon special request.
