Wolmanit Firestop

Firestop is a highly effective fire retardant VPT product which improves the performance of timber and plywood when exposed to fire. Wolmanit Firestop treated timbers will comply with all relevant international fire standards (e.g. EN13501-1: class B s2 d0), thus giving architects a wide choice in fire-related timber applications.

Timber treated with Firestop is suitable for interior and exterior applications and the most typical uses include internal wall and ceiling linings, external claddings, roof constructions, transportation, wooden scaffolding and pallets for the chemical industry. It controls ignition of fire, impedes flame spread across the wood surface and lowers the heat release from the wood-based substrate.

WJ Components is the only facility to offer this treatment in the UK.
