ISF Poly-Anchor is a low-cost one-piece polypropylene insulation fastener that is manufactured in the UK. The anchor body features a 35mm diameter head and a solid shank having a series friction grip ribs.

An 8mm hole is drilled into solid brick, block or concrete walls. The anchor is simply tapped through the insulation until embedded into the wall at a minimum embedment depth of 30mm.

Separate load spreading washers are available for this item.



The Poly-Anchor has no moving parts, making it quick and easy to install. Its multi-rib friction rings make this fixing ideal securing rigid insulation, EPS, High Density Rockwool and Composites to a wide range of solid masonry units.

The 35mm roughened clamping head provides excellent pull through resistance. And provides a good key for the application of render coats.
