SBT Tube System

Pressure plate/ Washer:

• SBIW-70 x 70: 70 mm square galvanized steel washer with rounded corners for attaching thermal insulation. Suitable for use with the SBT tube system only, the flat surface of the washer makes it ideal for attaching insulation board beneath adhered membranes, as they reduce the ‘ghosting’ associated with normal plastic headed tube fasteners used for insulation attachment. Requires one SBT fastener assembly per washer.

• Sarnabar 15/6: 3 mm thick linear bar used to attach the Sarnafil membrane in Sarnabar systems. Roll formed from steel strips galvanized to EN 10142-FeP03GZ275N, Sarnabar 15/6 is pre-punched with 6 mm diameter and 15 mm holes, alternating at 25 mm centres to speed installation.

• Peelstop 15/6: 1 mm thick linear bar, used at the perimeters and angle changes of adhered systems, to prevent membrane peel at vulnerable roof areas. 2.125 m x 30 mm Peelstop 15/6 is made from a roll formed and knurled steel strip galvanized to EN 10142-FeP03GZ275N. It is pre-punched with 6 mm diameter and 15 mm holes, alternating at 125 mm centres to speed installation.

• SBT Row Termination Washer: 105 mm diameter galvanized steel washer, for use with the SBT tube system only. Positioned at the end of intermediate perimeter rows of Sarnabar or intermediate rows of SFT fasteners, the SBT Row Termination Washer is secured with three fasteners per washer and prevents damage to the membrane.
