Eliminate thermal bridging
The tube washer practically eliminates thermal transmittance meaning insulation U-value calculations are greatly simplified as only minimal correction factors or penalties need to be considered. This not only saves time at the design stage but prevents any increase in material costs incurred by thicker insulation requirements.
Protects waterproofing membrane
Telescopic design means the tube and fastener are not locked together, preventing the fastener from being pushed through the membrane or a thin deck by foot traffic or materials placed on the roof surface.
Drillpoint size and thread ration
Engineered to ensure maximum thread grip and deliver the highest level of pull-out performance.engineered to ensure maximum thread grip and deliver the highest level of pull-out performance.
Secure against unwinding forces
Unique design ensures that the cyclic nature of wind uplift on flat roofing systems does not cause the fastener to unwind.
