Colour Options

  • All timber products should be acclimatised as required onsite to ensure moisture and temperature equilibrium with the surrounding environment prior to installation.
  • The cladding shall be installed (insert either horizontally or vertically)
  • The sub-frame shall be level and aligned and installed perpendicular to cladding direction over water-proof membrane at 450mm centres.
  • A breathable cavity shall be allowed for behind the cladding. To provide a completely serviceable external façade it is necessary to ensure that the wall cavity behind the cladding is able to allow any moisture ingress to evaporate and drain away. If the wall cavity is to be open to the weather
    during the cladding installation it is very important to prevent rain from entering the wall cavity. Wall cavities are not designed to drain large amounts of water and it is likely that the back of the cladding boards will be in prolonged contact with moisture which will cause extreme expansion and cupping.
  • The end stops and corner profiles shall be installed as required and fixed at 450mm centres by pilot drilling and screwing with countersunk stainless steel screws
  • The cladding shall be fixed at 450mm centres by pilot drilling and screwing with countersunk stainless steel screws evenly spaced from board edges.
  • The cladding shall be cleaned and maintained as required to avoid any accumulation of surface contaminants and to maintain the desired performance and appearance.
