Description

Decking system with Thermo-Pine timber boards on hidden fixing support rails and height adjustable pedestals.

Features and benefits:

  • Fixings are completely hidden, even between the boards.
  • Includes fast-fit clips, which cannot be dislodged once fitted.
  • Attractive appearance.
  • Support rails have industrial strength.
  • Boards can be removed with no damage (using specific tools - consult manufacturer for details).
  • Space-saving - can be installed to lower heights than traditional decking.
  • A matching cladding system is available - consult manufacturer for details.
  • Boards are free from grooves, with a convex surface – this prevents ‘cupping’ of the timber and eliminates water from pooling.
  • Quick, efficient installation - almost twice as fast as traditional methods.
  • Comes with a 25 year warranty.
  • Pedestal-based build-up height is from 67 mm.

Thermo-treated timber:

Timber which has been thermally modified using a computer controlled, kiln based process that preserves wood using heat and water. Wood is dry heated to around 130°C to remove all moisture, then steam heated to over 200°C and held at that temperature for several hours. Finally, it is water spray cooled to ensure a final moisture content of just 5%. It is:

  • Rich brown in colour.
  • Rot and mould resistant.
  • Lightweight to handle.

This product also has a low thermal conductivity.

After exposure to moisture and sunlight (and without any UV protectant oil) thermo-treated timbers will naturally weather down to a soft platinum-grey colour.
