Product Description

Drain outlets connecting waterproofing bituminous membranes to downpipes with a slightly conical structure for facilitating the laying of downpipes provided with a ribbed flange favouring adhesion to bituminous membranes and two rings placed on the shank acting as an antireflux sealing device between the outlet and downpipes. Products made of elastic material ensuring long-lasting tightness. The shank placed on the upper side of the outlet is provided with knurls so that leaf guards or gravel stops can be connected to the outlet.

Aerators suitable for waterproofing bituminous membranes allowing the leakage of the vapours generated underneath the waterproofing membrane without reducing its water-repellent capacity, so as to avoid any inconvenience arising from improper aeration, such as swollen coverings, curling, humidification of the insulation layer totally or partially losing its properties.

Universal leaf guards preventing gutters or downpipes from getting blocked, thus avoiding any obstruction due to the presence of leaves or other materials.”
