About Troldtekt line design

Design solution with an elegant and seamless expression

Troldtekt line design features milled grooves in the surface, with overlapping edges on both the short and long sides.

When you join the panels, the result is continuous grooves with a seamless look and invisible joints. You perceive the surface pattern as a whole, and it's hard to see where the panels meet.

The solution is available in four variants, which can be freely combined. You can choose to have equal or varying intervals between the grooves, determining the rhythm of the resulting look.

Benefits of choosing 


Troldtekt® line design

We combine design, acoustics and a healthy indoor climate.

Flexible design
Flexible design
Troldtekt line design gives you the freedom to combine brilliant acoustics and a healthy indoor climate with a unique look. You can join the panels together to create a seamless look with no visible joints. You can choose whether you want equal or varying distances between the grooves.
Outstanding acoustics
Outstanding acoustics
Troldtekt line design has the same excellent absorption capacity as our traditional acoustic panel. You can create a distinctive look in most types of buildings while regulating the acoustics with Troldtekt line design on walls or ceilings.
Multiple installation options
Multiple installation options
Troldtekt line design is ideal for spaces where acoustics play a major role in our wellbeing and comfort, e.g. in office environments or schools where we spend a large part of our time during the day. Troldtekt line design can be installed on both walls and ceilings, and you can choose the method that suits you best: direct screw installation or installation in a profile system.
Healthy indoor climate
Healthy indoor climate
Troldtekt line design ensures good acoustics, which is essential for a healthy indoor climate. What's more, Troldtekt acoustic panels are documented as free from harmful substances that can contaminate the indoor climate. The acoustic panels can also absorb and release moisture, which can make the indoor climate feel more comfortable.
Effective fire performance
Effective fire performance
Troldtekt line design is made from natural wood and cement extracted from the Danish subsoil. Although wood is an organic and combustible material, non-combustible cement encapsulates each individual wood fibre in the panel. This is why Troldtekt panels have low flammability and emit very little heat during a fire and almost no smoke.
