LAYING TECHNOLOGY
On level surfaces it is necessary that the breather pipe coming from the internal room emerges for 31 cm. for any diameters. Lay the first layer of waterproof membrane, drilling it by the pipe, heat
the surface that will cover the flange of the bellows base by flame and lay it.
Lay the second layer of waterproof membrane without bending it, insert the aerator. In case of tile roofs, the pipe shall go beyond the border of the tile hole for at least 30 centimetres, then the protection and the aerator with a Ø 100 shall be inserted in it.

SPECIFICATION
Supply and laying of steam exhaust aerators for aeration pipes in bathrooms, kitchens, etc., Ø 100 h. 305 mm. - Ø 125 h. 350 mm. and the relative bellows base for the
connection to the waterproofing, laid between two membrane layers.

N.B.: In case of a roof with concrete tiles, the tile protection is applied instead of the bellows base.
