SFT Tube System
Description

Thermally broken tube fastener consisting of a 15 mm diameter grey polyamide SFT tube, used in conjunction with either an SBF-T25, TI-T25or a suitable Sarnafil stainless steel fastener. The SFT tube has an integrated 50 mm diameter stress plate, with four large barbs which puncture and grip the membrane.

Only suitable for use in insulated Sarnafil applications. The Sarnafil membrane must be pre-punched with a Sarnafil SMP punch to avoid distortion of the membrane and tubes installed with the appropriate tooling to avoid overdriving.
