Both a building's users and its developers have a good reason to get excited about the new Troldtekt Plus 25 panels.
This specially developed acoustic panel sets a high standard for both sound absorption and building efficiency.
Danish manufacturer Troldtekt A/S introduces yet another innovative solution for the construction industry: Troldtekt Plus 25 is an acoustic panel that combines high sound absorption with significant practical advantages such as low weight, space-saving design and low overall costs.
In practice, Troldtekt Plus 25 is a two-layer panel but only 25 mm thick, just like Troldtekt’s traditional single-layer panels. A special acoustic liner made of non-woven acoustic fleece is applied to the back of the panel and ensures high sound absorption.
As a suspended ceiling, Troldtekt Plus 25 has a so-called alpha value of 0.9 (αw = 0.90), which means that it can achieve Class A sound absorption at a suspension depth of 200mm. The fact that the panel excels in the low frequencies (125-250 Hz) makes it perfect for applications such as classrooms and meeting rooms.
The acoustic fleece itself is so thin that the panel measures and weighs the same as a traditional 25 mm Troldtekt acoustic panel – without a backing layer. This makes it significantly easier to stack, cut, lift and assemble on site. With a thickness of only 25 mm and a weight of 11.5 kg, Troldtekt Plus 25 offers significant logistical and practical advantages including transportation, storage and installation.
Depending on the panel specified, reaction to fire is classed in accordance with EN 13501 as B-s1,d0 or A2-s1,d0 respectively. Cradle to Cradle Certified® at Gold level, Troldtekt wood wool acoustic panels are manufactured using wood from certified forests (PEFC/09-31-030 and FSC®C115450) and can contribute positively to a building’s BREEAM, WELL or LEED points.
