The Thermory® collection is produced by Brenstol, a Northern European manufacturer of profiled solid wood products. With more than 13 years of experience, it is one of the leading thermo-treated wood producers in Europe, offering a wide range of interior and exterior products. As a result of continuous product development, the Thermory® collection offers beautiful, durable and functional timber that is environmentally sound. All items are free of chemicals, harmless to use and do not originate from endangered rainforests.
Thermo-Treated Ash
Thermory® only use high quality ash for their cladding boards, harvested from well-managed forests in North-America where good growing conditions and strict drying standards are maintained. This range has been subjected to their ‘intense’ thermo-treatment’, which heats and steams materials up to a maximum temperature of 215°C, ensuring maximum stability and a dark, rich colour throughout the timber. This chemical free process also ensures a low moisture content, removes resin, reduces splitting strength and improves durability against decay. The end result is the transformation of responsibly sourced ash, a timber with limited exterior uses, into a cladding material with class 1 durability credentials equal to Ipe and Teak.
Board Lengths
Our thermo-treated ash cladding boards are offered in 2 length ‘groups,’ each with a different price. As such, you will be charged different metre rates if your order contains boards from separate groups. Precise stocks do vary, but we will always do our best to match your required tally. Please note that decking boards may be supplied over length, so you will need to ensure that your fitter has the correct tools on site to cut them down.
Board Length Groups
  • Medium – 1.5m to 3m
  • Long – 3.3m
Fitting Information
These boards are supplied with the Thermory® C7J profile, so are pre-grooved on the reverse for use with their innovative and time saving CLAD52 sub-construction. This is supplied in 68 x 26mm battens featuring pre-fastened clips that the cladding simply clips into. Alternatively, this cladding can be fitted in the traditional fashion.
Like all natural timber, Thermory® will begin to gently weather down once installed. This will include an attractive silvering/greying and the development of small, surface hairline cracks. Whilst many prefer to allow this appearance to develop, it can be checked through the regular application of Thermory® Thermo-wood oil. The boards can be sanded back at any time to restore the original tones.
