ROOF VENTING

Aerators art. 158 and art. 158.1 are suitable for use on roofs having pitches between 15° and vertical. They are used as cavity aerators. They can accommodate pipes up to Ø 110 mm.

Aerators art. 159 and art. 159.1 have the same function but with a front flange where the roofing material can be overlaid giving better safety margins against water back flow into the aerator.
For even higher safety it has a 7 + 3 mm. step. The two sizes are fitted with 18 mm. Dripedge.

The ridge has been carefully developed for the aeration of cavity in cold roofs where bituminous shingles or fibre cement sheeting is used. The ridge can be used on any pitch thanks to the labyrinth design which prevents the back flow of water by even the strongest of winds. It is also easily aligned thanks to a
specially designed hook system it has a built in insect net holes are pre-moulded into the ridge elements which are supplied with end closure caps. The ridge is made of moulded thermoplastic
which is flexible and resistant at both high and low temperatures.
