PVC VENTILATION AERATORS

The “UNIVERSAL” anti-surge nozzle is one of the most valid systems for connecting downspouts and drains in flat roofs, in the gutters of multi-pitched roofs and in the valleys of industrial warehouses. It is also particularly suitable for use on roofs made with membranes formed with a modified bitumen membrane such as APP, SBS, or coated bitumen. Its construction is studied in detail, in fact the construction has optimal characteristics to eliminate serious and costly drawbacks created by traditional unions on the market. The material used for the realization of the nozzle is IGOM, it is a synthetic rubber compound which offers a range of chemical and physical technical characteristics that can satisfy all the needs of an elastic article, in fact the suitably formulated IGOM provides a ” high resistance to degradation caused by the sun, ozone and other atmospheric and chemical agents. It can be used in a wide range of temperatures giving high flexibility at low temperatures and is stable over time, given its physical and mechanical characteristics. Therefore a material which, thanks to its excellent quality, ensures perfect efficiency over the years. The grille consists of a truncated body, of variable diameter, integral with a wide anchoring plate and which has knurls of the same material on the upper surface to facilitate adherence with the membranes. The shank is provided with two or more well positioned circular flanges, facing outwards, which, by forcing elastically on the internal surface of the exhaust pipe, ensure that the nozzle has anti-surge properties and a perfect seal: in fact, when inserting the exhaust pipe, they undergo an upward bending and consequently to the pressure exerted, they guarantee a perfect adherence with any type of hose. In this way, the passage of water vapors and any liquid masses (regurgitation) is eliminated which, filtering under the waterproof covering, invalidate the effectiveness of the insulation: a factor which naturally constitutes one of the most serious drawbacks for the waterproof covers

Art. 49.3 – 50
Assuming that the vapor barrier has already been installed on the slab, position the channeling unit Art. 51 on the highest points of the roof in simple support. Subsequently, the insulating panel is laid, suitably perforated for the passage of the central body of the canalizer dis. B or of the pipe dis. A. Lay the waterproof membrane layer by drilling it in correspondence with the canalizer. The aerator is placed and welded with hot air over the membrane itself.
