The nylon sleeve is specifically designed for use with large-hole non-penetrating gaskets, together forming a perforation-free fastening solution for rock wool insulation substrates in mechanical fixing systems.
The nylon material effectively blocks thermal bridging while providing excellent insulation and anti-corrosion properties, ensuring tight integration with screws for enhanced system stability
Compared to PP, nylon offers higher mechanical strength, improved heat resistance, and greater dimensional stability
