New alliance: Acoustic ceilings for cleaning the air

23:e feb. 2017
Troldtekt has entered into a strategic alliance with Photocat A/S about the development and testing of acoustic panels featuring new and revolutionary indoor-climate technology.

Acoustic panels which not only guarantee excellent acoustics, but which also improve the indoor climate through the use of new technology for removing harmful particles and aerosols from the air. That is the ambition of a new strategic partnership between Troldtekt and the Danish company Photocat A/S, a leading developer of new technologies for improving the indoor climate.

Removal of harmful particles

A test project has just been launched which is aiming to document that it is possible – through combining Troldtekt cement-bonded wood wool with Photocat’s technologies – to remove harmful NOx emissions and volatile organic compounds from the surrounding air.

- We are extremely pleased with our strategic alliance with Photocat, and we see considerable potential in the development of new technology for improving the indoor climate, says Peer Leth, CEO of Troldtekt A/S. 

The results of the project are expected to be ready by the end of 2017.
