H 60 - 90 Perforated Flange
TPE COLLARS are used to connect the waterproof bituminous felts to any through tubes or systems on the roofing. The slightly conical shape of the shank makes it easier to install through tubes and the perforated flange favours adhesion with bituminous sheaths.
The elastic material they are made with ensures long-term watertightness. 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 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, a thin coat of primer can be applied on the drain connectors beforehand.
