About Troldtekt rhomb

Acoustic panel with a three-dimensional look

Troldtekt rhomb is a design solution in which the acoustic panels contain rhombus-shaped patterns. When combined, they create a dynamic and scalable pattern with a distinct sense of depth. Three panels can be combined to form a hexagon, and with the Troldtekt rhomb hatch variant, four milled grooves are added to enhance the rhythm of the design.

All sides of the panel are milled with a bevelled edge, which gives precise grooves in the joints and emphasises the geometric design. The rhombuses can be arranged in repetitive sequences or more random patterns, giving the surface exactly the look the architect wants.

Design with proven properties

Behind the visual look, the well-known properties of Troldtekt are preserved: effective sound absorption, proven sustainability measures and the option of surface treatment in different colours. Troldtekt rhomb is therefore an obvious choice if you want to combine acoustic comfort with architectural geometry.
