Fire retardant for ThermoWood

Thermally modified wood, a.k.a. ThermoWood or thermo-treated wood has already been penetrating the market for a number of years. But so far there hasn’t been a Class B-s1,d0 fire retardant for ThermoWood that could be applied without pressure treatment. MultiPro System has now developed and certified such a fire retardant for thermowood – Ultra-TW.
