HR PROF

HR Prof is tested and approved internationally and meets the classifications of Euroclass B-s1-d0, (UK class 0 on solid wood, Euroclass C-s1-d0 (UK class 1) on plywood, K1 10 and K2 10.

HR Prof helps to extend the lifetime of treated wood, transforming it into a more fungal and blue stain resistant substrate.

Once absorbed into the surface of the wood, HR prof combines chemically within the cell structure but does not form a surface finish, which allows the wood to breathe naturally. In the event of fire, carbon char is restricted to the immediate area – preventing the flames from spreading.

Wood treated with HR Prof complies with EU construction products regulations, enabling customers to apply for a CE mark on treated timber. HR Prof is certified according to EU regulation number: 305/2011 (Construction Products Regulation).
