Composition:
Duggan Profiles & S.S.C. Insulated Gutters comprise an external membrane lined weather skin, PIR rigid insulation and an internal liner skin. The specification of each can be configured to suit the individual design requirements. The inside and outside gutter skins are bonded to the insulation and the flanges where the surfaces come together are joined by clinching or riveting. For applications requiring thermal breaks please consult with D.P. & S.S.C.
Joints:
Each gutter includes an overlap which forms a lapped joint with the abutting gutter section. Stainless steel rivets, compatible sealant and a heat welded membrane strip secure and seal the joint. |
Welding Strip:
1.5mm thick x 150mm wide grey PVC, supplied if ordered, in rolls. The standard joint is made on site by heat welding 50mm to weather sheet of each gutter. Customers should specify if Welding Strip is required when ordering gutters.
