About Troldtekt Plus

High acoustic performance 

Troldtekt Plus is a two-layer acoustic panel comprising a Troldtekt cement-bonded wood wool panel with a laminated backing layer. The product is available in two series, each with a range of products:

Troldtekt Plus with mineral wool : In this solution, the backing comprises a layer of sealed mineral wool measuring either 20 or 40 mm, ensuring optimal sound absorption. The panel itself is 25 or 35 mm thick. The backing layer is cut to size and set back from the panel edges so that it fits between profiles or wooden battens.

Troldtekt Plus with fleece: With this option, the backing comprises a thin acoustic fleece, ensuring high acoustic effect at minimal thickness. Troldtekt Plus with fleece is available in thicknesses of 25 or 35 mm and weighs as little as 10.7 kg/m2.
