To ensure its fire resistance, the sawn timber is carefully treated before being delivered to distributors and end users. In order to achieve an end result that meets the requirements, the sawn timber is treated several times with Teknosafe 2407-00, a fire-retardant coating which guarantees the highest possible fire class – P1 – for wood products. End-use applications for the fire-resistant products include particularly exterior cladding and ventilation gap surfaces. The protected products are classified according to Bs-1, d0 EN 13501-1.
The exterior cladding of apartment buildings and care facility buildings in Finland requires structural fire protection or a separate sprinkler system to prevent the spread of fire. Koskisen’s fire-retardant coating system for wood can replace these methods.
“All in all, sawn timber treated with a fire-retardant coating can resist fire for longer than ordinary timber, and furthermore it does not catch on fire very easily. The treated timber is also weatherproof,” says Vesa Saarelainen, Sales Manager for Koskisen Houses, explaining the advantages of fire-protected timber products for the customer.
