Warm Roof Nails
Warm Roof Construction
Helical nails are a quick and reliable fixing for use in warm roof applications. Unlike traditional nails, they rotate as they are driven in, inducing a self-tapping action and consequently do not split or bounce timbers. Staifix products are available from builders merchants and other specialist distributors.

Super-8 Headed Helical Nail for Flat Roofs
Super-8 headed helical nails secure plywood/insulation composite roof decks to timber joists. They are manufactured in three standard lengths which suit panel depths from 85mm to 160mm.
For applications with joist centres of either 400mm or 600mm, nails are typically installed at a minimum density of 6.9 per square metre.
The 18mm diameter head simplifies installation.
|145mm (panel depth 85-110mm)|
|170mm (panel depth 115-135mm)|
|195mm (panel depth 140-160mm)|
Other lengths are available on request (min. 135mm).
|Bags of 25|
|Boxes of 400|
Super-7 Thor-Helical Nail for Pitched Roofs
Super-7 nails fix counterbattens to rafters and install flush to the timber. They are manufactured from stainless steel and are engineered with the precise Thor-Helical patented helix, and so provide maximum corrosion resistance and excellent holding power.
Other lengths are available in increments of 5mm.
Note: Ancon recommends a minimum counter batten thickness of 38mm.
|160mm - Box of 400|
|165mm - Box of 200|
Super-7 nails meet the technical requirements of the NHBC.
