The KOO2 decorative panel has one false groove, so the final effect is more rhomboidal than the traditional panel. You can also combine KOO2 with KOO4 and KOO4 panels with no false edges for an interesting and individual finish. The thickness of the panels ensures a real wood feel in all profiles.

The KOO interior panel is a 21mm thick panel with concealed fixing. The concealed fixing leaves hidden fixing marks and the result is a beautiful, nail-free wooden surface. The KOO family of interior panels, representing top Finnish design, was designed by interior architect Kari Lappalainen. The KOO2 interior panel is made of pine. Another material option is birch, which is also suitable for saunas in translucent white colour.

We recommend using a dyckert-type nail or the staples listed below. Remember that finishing nails are not suitable for panel installation. A pneumatic nailer is recommended for fastening panels. The length of the nail should be at least three times the thickness of the panel. Adjust the nail's countersink depth: the nail must not remain raised above the panel's surface or sink too deep, breaking the panel's surface.
