The Spit ISO Universal Insulation Anchor is a reliable hammer-in fixing solution designed specifically for attaching expanded polystyrene (EPS) and mineral wool insulation boards within External Thermal Insulation Composite Systems (ETICS). With its thoughtful engineering and ease of use, it's ideal for both professionals and DIYers tackling insulation installations.
This anchor features a strong, rigid design with a pre-assembled plastic nail made from watertight glass fibre, making it easy to install and extremely resistant to weather and moisture. Its unique construction ensures a low thermal transmittance — less than 0.002 W/K — meaning it helps maintain the integrity of your building’s insulation envelope.
The hammer-in mechanism allows for quick, fuss-free installation, and with low embedment depth (only 25mm), you’ll save time and effort with every fix. Its special plate surface offers excellent render adhesion, making it suitable even for thicker insulation boards without compromising hold or finish.
