Flame retardant OSB

For applications that call for a Euroclass reaction to fire, our SMARTPLY MAX FR range can be used. SMARTPLY MAX FR B is the first Euroclass B flame retardant OSB manufactured in the UK and Ireland to feature wood flakes treated with flame retardant solution before pressing. SMARTPLY MAX FR B is also certified as SMARTPLY MAX FR/FR BUILD, for use in timber frame buildings when extra mitigation measures are required in the Structural Timber Associations' “Design guide to separating distances during construction” for timber frame buildings above 600m2 total floor area.
