for bituminous felts


TPO COLLARS are used to connect waterproof bituminous felts to any through tubes or systems on the roofing. They have a large smooth flange for excellent welding to TPO synthetic felts. The h 250 models can be easily cut by following the marked lines and bringing the outfeed diameter to 20, 25 or 30 mm for Ø 18 and to 30, 35 or 40 mm for Ø 28. h 400 models are instead available in four different diameters and the shank has a slightly conical shape to make installation easier. They provide excellent resilience to deterioration caused by the sun, ozone and other weather agents or chemicals normally found in the atmosphere. The elasticity of the material allows for excellent flexibility even at low temperatures, which ensures mechanical and physical properties are maintained over time. They are 100% compatible with prefabricated TPO synthetic felts. We recommend thoroughly cleaning the collar and felt near the area where the connector will be welded.
