Firepro B400 Spiralite is a comprehensive fire protection system for structural steel which uses a unique spiral screw fixing system method to give fast, clean and cost effective installation for up to 2 hours fire protection. This dry fixing system avoids all the associated mess and the additional labour time taken by the traditional glue method of fixing. The easy hand tool application also allows for quick visual quality control checks. SPIRALITE is tough and durable and has excellent thermal qualities. The 200kg density board ensures a robust and resilient installation. Furthermore, SPIRALITE is vermin resistant and does not run the risk of deterioration after the area is closed off. SPIRALITE repels moisture and does not degenerate when exposed to weather elements during construction.
