Product name ThermoWood® Pine Optima Channel 10 Cladding
Material Timber / wood
 
 
 

Silva ThermoWood® is an attractive, sustainable solid wood material produced using a chemical-free natural process involving heat and steam. This thermal modification process makes it durable, dimensionally stable, resin-free, and even changes its colour to a pleasing warm brown.

This ThermoWood Channel 10 profile is part of the Optima Series, a range of precision machined profiles that feature unique design details that make them easier to install and to help them perform better. Cladding profiles in the Optima series feature a discreet nail line for ease of installation together with a substantial overlap where the boards connect to accommodate the natural movement in wood.

It is possible to install the Optima Channel 10 pro?le either horizontally or vertically. A square-sided recess where the boards meet creates bold shadow lines that will accentuate either the height or width of the façade. Boards connect with a tongue and groove system for easy installation.

ThermoWood is produced from Finnish-grown European Redwood (Scandinavian Pine) which is heat-treated to temperatures in excess of 200 degrees Centigrade. This process makes it an ideal material for use in exposed areas such as external wall claddings.

Product Details

  • Sizes: 20 x 117mm / 20 x 142mm.
  • Grade: Silva ThermoWood is produced from live knotted A/B grade, European Redwood.
  • Profile: Optima Channel 10 has a tongue and groove connection and provides deep, bold shadow lines created by the recess.
  • Installation: Horizontal or vertical.
  • Surface texture: Smooth.

Optima™ Series

The Optima Series is a range of precision machined cladding profiles designed and made by Silva for optimum performance.

Optima profiles feature unique design details that make them easier to install and to help them perform better. 

Optima profiles are produced in 'high performance' wood species and come with a range of neat corner and trim solutions.

Optima Features

  • Tapered tongue and groove for faster installation.
  • Wide fixing area.
  • Large area lowers the risk of water ingress.
  • 10mm overlap to accommodate movement.
  • Hidden fixing.
  • 10° bevel on recess creates an attractive profile.

Key Properties

  • Colour: An attractive warm brown colour consistent throughout the section of the piece.
  • Durability: Silva ThermoWood has a decay resistance of durability class 2 (durable) according to the EN 113 standard. A service life of 30+ years can be achieved, or 60+ years if a surface coating is applied at the outset and maintained periodically.
  • Stability: The lower equilibrium moisture content and the changes in the chemical composition of the wood during the heat treatment process make Silva ThermoWood less able to absorb and release water, thereby improving dimensional stability.
  • Density: The density of Silva ThermoWood is 350 – 480kg/m3 when its moisture content is 6% (typical for RH = 65%, t=20° conditions).
  • Thermal properties: According to VTT tests, ThermoWood’s thermal conductivity λ10 is in the region of 0.099 W/(m K). The corresponding value for untreated kiln-dried European Pine is 0.12 W/(m K).
  • Grading: To ensure Silva ThermoWood products meet the highest quality standards, only specially selected sound (live) knotted wood is used in the production process. 
  • Sourcing/certification: Silva ThermoWood is sourced from well-managed and sustainable forests that are fully certified under the Pan European Forestry Certification (PEFC) scheme.
