The Troldtekt series’ two-layer acoustic panel, Troldtekt Plus, consists of a classic Troldtekt panel with a backing layer of sealed mineral wool.
The backing layer is cut to size and set back from the edges of the panel so that it fits between profiles or wood battens. Troldtekt Plus enables the acoustic ceiling and backing layer to be installed in one and the same workflow, saving construction time. Troldtekt Plus acoustic panels are ideal for the refurbishment of existing ceilings and for suspended and floating accoustic clouds.
The Troldtekt Plus solution saves space and, with dimensions down to 47 mm thick, you can achieve almost the same sound absorption properties as with a suspended Troldtekt ceiling and a separate layer of mineral wool.

With Troldtekt Plus, you can achieve almost the same sound absorption values as with a Classic suspended Troldtekt ceiling with mineral wool behind but with a lower fitting height.
Troldtekt Plus is available with one 18 mm or 40 mm layer of mineral wool on the back:
