Thermowood Redwood - Carbon Neutral Timber Cladding
Verified by manufacturer 4 months ago
Thermowood has a high resistance to moisture and decay which makes it a good option for exterior cladding. Thermowood is a straight grained softwood which offers a more consistent finish.
Application
Particularly suited to external cladding applications. Also suitable for internal cladding applications. Example applications include, but are in no way limited to:
- Public buildings.
- Residential buildings.
- Schools.
- Commercial buildings.
- Restaurants.
- Offices.
Description
Softwood redwood timber cladding.
Features and benefits:
- High resistance to moisture and decay which is beneficial for exterior cladding applications.
- A straight grained softwood that offers a more consistent finish.
- Thermally modified to increase stability and provide resistance against shrinkage, swelling and distortion.
- Heat treated to a temperature of 180 degrees.
- Resistant to sapwood treatment.
- Wide choice of standard profiles.
Moisture movement:
Wood’s moisture content will change relative to its surroundings. Different species have different degrees of movement and this must be accounted for in cladding design.
Good design and installation practice will help minimize the effects of moisture:
- Use eaves and overhangs to deflect rain - or flashing to protect the board tops.
- Finish cladding at least 200 mm from the ground or a horizontal surface. Where possible use a surface that diffuses rain, such as gravel.
- Board widths should generally be 4 to 6 times board thickness (typically less than 150 mm).
- Design detailing must include measures that minimise water penetration.
