Secure insulation fastening with Spit PTH-KZ

Practical benefits

Reliable holding in masonry: The sturdy steel nail delivers strong expansion in brick and aerated concrete, ensuring you anchor insulation boards up to 120 mm securely.
Minimal thermal bridge losses: Designed with an overmoulded head, the anchor helps you avoid heat bridging through the metal pin across your external facade.
Optimal plaster and render adhesion: The 60 mm plate features a textured surface so you achieve a strong bond when applying exterior base coats and render.

In a nutshell

The right choise for

With the Spit pth-kz insulation anchor, you secure rigid insulation boards firmly and swiftly to brick walls and aerated concrete. Thanks to the sturdy steel drive pin, the polypropylene anchor expands powerfully inside an 8 mm drill hole, preventing panels up to 120 mm thick from sagging or detaching over time. The overmoulded head design minimises thermal bridging across the metal pin, keeping external facade insulation thermally efficient. In addition, the 60 mm textured plate head provides an optimal bonding base for exterior base coats and render, ensuring a clean, reliable, and durable finish on every renovation or new build project.
