This pattern can be fire-retardant treated with the 100% natural fire-retardant Burnblock® to the desired reaction to fire class. LDCwood® ThermoWood® pine stands for timber in its purest form. Due to its light weight, Thermo-D pine is easy to handle. Thermo-D pine is 'centre cut', the best quality, which ensures a stable and shape-retaining plank. Thermo-D pine from LDCwood® is always FSC® or PEFC certified. Smooth connections and loyal partnerships with the sawmills help to ensure a low ecological footprint.
