“UNIVERSAL R” ANTI-BACKUP ROOF DRAIN IN IGOM.CE WITH MESHED FLANGE is one of the most valid systems for connecting rainwater pipes and drains on flat roofs, gutters of multi-pitched roofs and industrial buildings. It is particularly suitable for use with all kinds of APP, SBS modified bituminous membranes as well as liquid bitumen coatings, liquid cements polyurethane resins, and two-component waterproofing products. This particular item has been studied right down to its smallest details so as to optimize its characteristics thus eliminating problems caused by traditional drains available in the market. The drain is made from IGOM.CE, a specially formulated compound of synthetic rubbers realized by ITALPROFILI ® that allow to obtain high physical, chemical and technical properties as well as a flexible product. IGOM.CE is highly resistant to UV rays, ozone and other atmospheric and chemical agents. It can be used in a wide temperature range as it is extremely flexible at low temperatures and stable over time thanks to its physical and mechanical properties, which therefore assure maximum performance throughout its lifespan.
The drain consists of a truncated body available in various diameters solidly attached to the a 5x5mm meshed flange all made from the same materials to increase the adhesion of the waterproofing products. The stem piece of the unit has two or more strategically placed circular ribs which face outwards and when forced into the drain pipe prevent backing-up and form a perfect seal. The seal rings are compressed upwards when inserted into the downpipe and thanks to this pressure fit they guarantee optimal seal with any type of pipe. Thanks to the presence of the external seal rings the passage of water vapour or back-up of water into the roofing system is prevented. This is particularly important where insulation is involved as it could compromise the insulation its self, factor that constitutes one of the main problems in roof waterproofing.
