Flat roof pipe collars - are used to connect the bituminous felts with existing pipes or systems on the roofing. They have a large smooth flange for excellent adhesion with bituminuos sheaths.
H 400 models are available in two different diameters and the shank has a slightly conical shape to make installation easier.
The elastic material they are made with ensures longterm 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 collars beforehand.
