Cement-bonded wood wool panels

Troldtekt sound absorbing acoustic panels are made using nature's own materials - wood (wood wool) and cement


The wood used in Troldtekt acoustic panels is Norway spruce from local forests. Danish timber is a renewable resource, as more is planted than is logged. Wood is also a CO2-neutral resource, as it absorbs as much CO2 during its growth as is emitted during its management, logging and transportation.

Troldtekt acoustic panels are FSC®-certified (FSC®C115450), which means that we can offer products produced with wood that originates from responsible forestry operations.

Troldtekt acoustic panels are also PEFC-certified. This means that we can supply certified acoustic panels manufactured using timber from forests which are documented as being sustainable and which comply with the PEFC principles.

In our production of Troldtekt acoustic panels, we use certified wood only. As a customer, you can choose whether you want your Troldtekt acoustic panels to be FSC or PEFC™-certified.

Troldtekt cement


The production of Troldtekt panels uses only cement from Aalborg Portland A/S, which extracts the raw materials from the Danish bedrock with minimal environmental impact.

Chalk and sand are the key raw materials used to make Portland cement. Both chalk and sand is extracted in Denmark, where sand dredging helps keep sailing channels navigable.

Aalborg Portland is certified under the ISO 14001 eco-management system and the European EMAS (Eco-Management and Audit Scheme).
