HR-Prof is suitable for internal and external timber. It has non-flammable properties which restrict ignition and the spread of flame. The product is easy to apply, possessing high diffusion properties enabling it to quickly penetrate into the surface of the substrate.
HR-Prof is typically used on cladding, log cabins, garages, summer houses, staircases, bathrooms, saunas and pool enclosures. Critical engineering properties i.e. strength, durability, hygroscopicity and corrosivity are not compromised.
HR-Prof is renowned as a market-leading flame retardant for timber having been applied to many prestigious projects including the Olympic Stadium.
Product benefits include:
- Fully tested on a range of timber substrates
- Ecologically friendly
- For internal and external use
