Sarnafast® Tube SFT-50
The SFT thermally broken tube systems consists of the SFT tube assembled with the appropriate screw fastener. The SFT tube system is used to restrain Sarnafil S/TCS mechanically fixed membranes, by installing rows of SFT fasteners in the side lap of the sheet, at centres determined by the wind uplift and the deck type.
- Eliminates cold bridging. Standard rigid steel fasteners can add in excess of 10mm to the required thickness of the thermal insulation.
- Higher fastener design loads which can reduce numbers of fasteners required
