Cladding & Weatherboard
H3 or Thermowood Treated

Our Select Grade boards are chosen carefully to comply with strict Australian Standards. Depending on individual species, Select Grade has a much more uniform appearance and has a very clean look.


Our Cladding and Weatherboards are generally available in the following common sizes:

Main lengths: 3.6 / 4.0 / 4.2 / 4.8 / 5.4 / 6.0

Shiplap: 95x12.5 / 140x18 / 141x19 

Weatherboard: 170x19 Checked & Chamfered

ThermoWood WarmClad decay- and weather resistance are important characteristics for a cladding board. WarmClad is an excellent choice for exterior cladding. Its decay resistance class is I-II and its usable life is many times greater than that of untreated wood. WarmClad’s moisture content is half that of normal wood and surface splitting caused by UV-radiation will be less than with normal wood.
