Troldtekt tiles results in a design with a pattern of rectangles which can vary in size. The solution consists of quadratic acoustic panels with milled parallel grooves in the surface.
The panels are available in five variants, which can be freely combined. Panels can also be rotated 90 degrees, resulting in a broken and more varied look in the surface.
A half groove has been cut on all sides of each panel, so that an extra groove of the same size is formed where two panels join.
