  • Anti-fungicidal properties
  • A very good fungicide
  • Without colour or odour
  • Non-toxic
  • Solvent Free
  • Not harmful to the environment
  • For internal and external use
  • Once dry it is not broken down by water or humidity
  • Does not leach
  • Accelerated Weathering

This was performed according to NT FIRE 053 Method B which involved accelerated weathering by cycles of rain, drying and also UV light for a total time of 1000 hours. The accelerated weathering was performed between 5 November and 17 December 2007 by SP Technical Research Institute in Sweden.

HR Prof fire performance properties will not compromise other critical engineering properties in the timber such as strength, durability, or hygroscopicity.

HR Prof Flame Retardant is not harmful to the environment – Environmentally friendly materials are essential for a cleaner world, follow the link below to sustainable construction.

HR Prof is simple to use and safe to apply. Possessing high diffusion properties it quickly penetrates the structure of the substrate. Unlike intumescent systems it does not require an additional protective finishing coat. However, if required HR Prof can be over-coated with wood stains, varnishes and some paints (tests may be required before over-coating please contact us for further details).

HR Prof has non-flammable properties, which become part of the substrate, restricting ignition and the spread of flame. It will not wash out from the surface of the substrate after drying, it is not converted into smoke when exposed to high temperatures, and carbon char is restricted to the immediate area. Materials treated with HR-Prof when exposed to temperatures of up to 1700 C are subject to charcoal forming, severely restricting the spread of flame.

HR Prof for use in timber frame buildings, external wood cladding, on staircases, trusses, doors, joists, floors and walls, on stables, log cabins, boats, fencing and garages – inside and outside. Once dry it is not affected by moisture so can also be used in kitchens, bathrooms, saunas and swimming pool enclosures. Timber pre-treated with HR PROF (Holz Prof) once dry does not react with galvanised steel ( zinc), stainless steel, brass, gun nails or zinc coated screws, whether the application is internal or external.
