+44 (0)1275 794735 Website

Application

Suitable for use in horizontal and vertical cladding scenarios.

Description

Created from thermally modified New Zealand plantation timber. A fine sawn face or textured face allows a depth of grain, and optimal coating performance.


The thermal modification process means enhanced stability, reduced resin content, is a beautiful homogeneous brown colour, and is naturally durable so does not require any chemical preservatives.


Features and benefits:

  • Wood species: Thermally Modified Radiata Pine (Pinus Radiata).
  • Durability Class 2
  • Available in a range of architectural profiles and can be supplied factory coated.
  • The range offers a renewable alternative to some of the more traditional Larch or Cedar cladding that the construction market are used to.
  • FSC certified plantation timber. This combined with the Thermal modification process permanently changes both the chemical, and physical properties of the timber.
