Smartpanel Single- and Double- boards are just as suitable for ceilings as walls. They replace the traditional wood panel, but you now don’t need to worry about sanding, painting, knots or shrinking of the wood. Install the panel vertically, horizontally or in any angel you may wish – the possibilities are nearly endless. Smartpanel Double is 3630 mm long and is made of double panels, so the installation goes quickly. Another advantage is that you will have minimal amounts of joints.
