Troldtekt® Plus

Easy-to-install new acoustic ceiling

Problems with noise and poor acoustics can be solved with a new acoustic ceiling. However, most people are daunted by the thought of having to remove the existing ceiling – a comprehensive process which causes inconvenience and generates dust. But this can be avoided.

You install Troldtekt Plus directly on wooden battens fitted to the existing ceiling and this saves you the trouble of removing the old ceiling. Drop sheets and a rolling scaffold are all that is required and the refurbishment can be completed in just a few days.

Two-layer acoustic panel

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.

Troldtekt Plus

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:

 Width (mm)  600        
 Length (mm)  600/1200/2400        
 Thickness (mm)    43
 Weight (kg/m2)          
 - Fine    11.8  15.2  13.4  16.7
 - Ultrafine    12.6  16.5  14.2  18.0
 - Extreme fine    12.9  16.8  14.5  18.3

The Troldtekt product configurator provides a good overview of all available Troldtekt combinations. Select the panel type "Troldtekt" and click your way through the options to specify your product. After only a few clicks, you get the opportunity to download a dynamic specification, AutoCad drawings and an installation instruction for the specific product.

Removable ceilings

Troldtekt Plus is also the ideal solution for removable ceilings where workmen may require later access to installations above the ceiling. In profile systems such as Troldtekt T35 for concealed or exposed fitting, you just tilt up the acoustic panel to inspect and maintain installations above the ceiling.

The back of the mineral wool is covered with non-woven material and glued to the back of the Troldtekt panels, so workmen completely avoid contact with mineral wool fibres.

Floating acoustic clouds

Floating acoustic clouds using Troldtekt or Troldtekt Plus are an ideal solution if it is not possible to fit Troldtekt acoustic panels to the entire ceiling surface. 

Floating acoustic clouds create an easy and elegant acoustic solution for defined areas.
