Wood panels with hidden nailing

Read the instructions carefully before installing the panels

Before installation

  • NB: The panels are only for indoor use and they cannot be in direct contact with water.
  • Any defects in the goods can be referred to only before installing them!
  • Make large surfaces out of the same production lot.
  • The temperature and humidity of the room need to be normal. The room temperature has to be approx. 20°C and the RH of the room approx. 40%. It  means that the walls and ceiling of the room needs to be dry and the windows and doors have glasses.
  • The panels should not be exposed to over 110°C of continuous heat.
  • The temperature and humidity of the panels should be stabilized to the same temperature and humidity than the one in the installation environment, approx. 3 days before attachment. You do not need to open the whole packages, make a hole to the end of the packages, from where the possible humidity can be removed.
  • Install the panels immediately after removing the plastic packaging.

Background

  • The distance between the joists should be about 400 mm or less, so the roof does not begin to ”slouch”. The thickness of the joists 45×45 mm (min 20×40 mm).
  • Ensure adequate air circulation behind the panels. If necessary, remove the bottom panels or attach reverse panels.
  • Make sure that the bottom panels are straight, even if the ceiling is uneven.
  • We recommend that you install the panels by using a stapling gun that is operated by compressed air.
  • The nail is shot slantwise from the nailing notch in the tongue, thus the nailing point will be as invisible as possible.
  • Leave an expansion gap of 10-15 mm between the panels and the wall. The seam will be covered by a ceiling moulding.

Safety

  • Lights or heavy objects must not be attached to the panel, they need to be attached directly to the joists.
