Usage of insulation board

Insulation boards (also known as standard boards) are wooden fibreboards that are designed to offer additional insulation, sound muting and increase in constructional rigidity in constructions of interior walls, ceilings and floors.


  • 100% natural wood fibres
  • Additional thermal insulation
  • Good sound insulation material
  • Supports insulation materials like loose and blown wool
  • Easy to process and install
  • Natural and breathable material
  • Possible to plaster (board with thickness 25 mm)

Installation of insulation boards

It is advisable to keep the insulation boards in the same room they are to be installed in for 2-3 days before installation — this helps to balance the moisture inside the boards with humidity of the surrounding air. The boards are placed sideways and bars are put under and between them, so that the boards are exposed to air.

The boards are fixed to wooden surfaces with nails or staples. We recommend using galvanized nails with large nail heads. Nails or staples are inserted 10–20 mm away from the edges with 150 mm gap between them; in central area the distance between nails/staples is 300 mm. You should use 40 x 2.2 mm nails or 1.7 x 25 x 32 mm staples in case of a 12 mm board. When the thickness of the board is 25 mm, you should use 70 x 2.5 mm nails or 1.7 x 25 x 58 mm staples. When the insulation boards are later covered with wallpaper, it is advisable to observe that the distance between the central nail rows does not exceed 400 mm.

The boards should be glued to stonewalls with construction adhesive (e.g. Soudal etc.). The base surface must be flat and dust free. Apply stripes of adhesive to the backside of the board, approximately 30 mm away from the edges. Apply dots of adhesive to the central area of the board, approximately one dot after every 200 mm. Support the boards if necessary. When using glue, follow the instructions of the manufacturer.

Insulation boards can be covered with wallpaper, paint or plaster. Fill nail head holes and gaps between the boards first. Before covering the insulation boards with wallpaper, increase the adhesiveness of the boards by undercoating them with adhesive dispersion or wallpaper glue. Follow the instructions of wallpaper and wallpaper glue manufacturers. It is advisable to use a stronger adhesive (this helps to stiffen the underlay of the wallpaper).
Insulation boards may be transported only in covered car to protect the boards from weather conditions. The manufacturer has a right to change the way of packaging and amount of goods on a pallet.
