Ventilation chimney – a unique structure, which can be adjusted to the roof inclination, in the 20-50 degree range, and combined both with the steel roofing tiles and trapezoid sheets. The base plate, with jointed cap, installed on the roof in a permanent and tight way, is easily joined with the chimney tube, thus providing a stable whole. It comes in a wide variety of colours, compatible with the majority of our sheet colours.
