Usage

The SBT thermally broken tube system is suitable for use with the Sarnabar 15/6 (Sarnabar mechanically fastened or loose ballasted systems), the peelstop (adhered system) and SBIW-70 x 70 pressure plates (mechanically fastened insulation system). 

SBT fasteners must be installed with the appropriate Sarnafil TP Installation tool to ensure the correct fastener setting and to eliminate damage to the SBT tube.

Prior to installation, the Sarnafil membrane must be pre-punched with a Sarnafil SMP punch to avoid distortion of the membrane.
