Troldtekt^® Plus

Troldtekt Plus is a two-layer acoustic panel comprising a Troldtekt cement-bonded wood wool panel with a laminated backing layer. The backing layer is either a thin acoustic fleece or a layer of sealed mineral wool. The backing layer is cut to size and set back from the panel edges so that it fits between profiles or wooden battens.

Because Troldtekt Plus consists of both an acoustic panel and a backing layer, both are installed in one and the same workflow. This ensures a high acoustic effect and saves time at the building site. 

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

With mineral wool: Low installation height, high effect

When you choose Troldtekt Plus acoustic panels with mineral wool, the back of the mineral wool is covered with non-woven material and glued to the Troldtekt panels. This prevents builders from coming into contact with mineral wool fibres. 

The solution also saves space, because with an installation height of down to only 47 mm, you achieve almost the same sound absorption as with a suspended Troldtekt ceiling where acoustic panels are installed with mineral wool backing. This makes it an obvious choice for rooms with relatively low ceiling heights.

Troldtekt Plus is available in variants with either 20 mm or 40 mm sealed mineral wool. Both can be installed directly onto new wooden battens, so you don't have to remove the old ceiling when renovating. All you need is some drop sheets and a mobile scaffold.

With acoustic fleece: An effective and light alternative

You can also choose Troldtekt Plus with an acoustic fleece. Here, the thin fabric – a special acoustic fleece – is glued to the back of the Troldtekt panels. This ensures effective sound absorption without the use of mineral wool. 

The advantage is that the panel measures and weighs almost the same as the classic Troldtekt acoustic panel without a backing layer. This makes it easier to transport, stack, cut and lift during installation. By avoiding mineral wool, you also save on purchasing and transport costs.

When you install Troldtekt Plus panels with an acoustic fleece as a suspended ceiling, you can significantly improve the room’s acoustics. The same applies in the low frequencies (125-250 Hz). We recommend an installation height of 200 mm. At lower installation heights, the effect is still higher than with classic Troldtekt acoustic panels – but not as high as when you install Troldtekt panels with mineral wool backing.
