Our FireWright fire retardant timber treatment is a natural and 100% biodegradeable treatment. We use an autoclave to impregnate plywood with our treatment. We accept a range of plywood species. To view the full list, please refer to our classification sheet.
Our specialist kiln drying facility allows us to return plywood to an appropriate or specified moisture level post-treatment, supporting construction standards to hold 10–18% moisture.
BURNBLOCK® fire retardant treatment can be applied to a wide variety of timbers, from solid timbers such as pines, oaks and red cedars to eucalyptus and birch plywood scaffolding boards for construction projects.
Although BURNBLOCK® is 100% natural and biodegradable, once impregnated into timber it will last the lifespan of the timbers we are certified to treat. This is a result of the pressure impregnation process. BURNBLOCK® will also achieve the same fire classification throughout the life of the timber.
We provide a Declaration of Performance, in line with our CE Mark certification for each of our fire retardant treatments. The legal requirements audit factory production control of the fire retardant facility and ensure the consistency of performance of the manufactured products.
