Sarnabar® Tube SBT-20

The SBT thermally broken tube system consists of a 15mm diameter grey polypropylene SBT tube, assembled with the appropriate screw fastener. The SBT tube system is used to fix Sarnabars when installing either a Sarnafil S/TCS mechanically fixed Sarnabar system or a Sarnafil G/TCG loose laid ballasted system.  The SBT tube system is also used in conjunction with the SBIW insulation washer, to fasten mechanically fixed insualtion.

  • Eliminates cold bridging. Standard rigid steel fasteners can add in excess of 10mm to the required thickness of the thermal insulation.
