The collars h 60-90 perform the function of connecting the waterproofing membranes of the roof with any through pipes or installations present on the roof. The slightly conical tang facilitates installation in through pipes. 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 materials allows for excellent flexibility even at low temperatures, which ensures mechanical and physical properties are maintained over time.
The perforated flange facilitates adhesion with bituminous sheaths. The collars are 100% compatible with APP and SBS prefabricated bituminous membranes and bituminous coats. A sandwich installation between the two layers of membrane is recommended to achieve top performance. To improve adhesion, the collars can be pre-coated with a light coat of primer.
