What Troldtekt does

Troldtekt A/S is a Danish manufacturer of cement-bonded wood wool acoustic panels for ceiling and wall cladding, founded in 1935 and headquartered in Troldhede, Denmark, with 101–250 employees. The company produces a portfolio that spans core acoustic panel lines (Troldtekt akustik, Troldtekt akustik Plus, Troldtekt ventilation, Troldtekt agro), a design series of routed-pattern variants (line, v-line, tilt line, dots, curves, tiles, rhombe), fire-rated A2 variants, ceiling track systems (C60, T24, T35), and accessories. Its underlying technology is a wood-cement composite combining certified wood and cement that delivers sound absorption up to αw 0.95–1.00, moisture tolerance up to 98% humidity, fire classification to EN 13501, and a minimum 50-year service life. From 2021 onward, the company has also produced panels based on Aalborg Portland's FUTURECEM low-CO2 cement, reducing product CO2 footprint by approximately 30–36%. Revenue is generated from one-time sales of panels and systems to a diversified base of professional buyers (architects, contractors, installers) and private homeowners across Denmark and export markets including Germany, Sweden, Norway, the UK & Ireland, New Zealand, the Netherlands, and Belgium/Luxembourg, distributed through direct sales, dealer networks, and three Danish showrooms.

Troldtekt's commercial model is sales-led: dedicated sales and technical support teams consult on specification, pricing, and installation for both large construction projects and smaller renovations, supplemented by web-based acoustics calculators, product configurators, and an extensive download center for specifiers. The company holds a stack of compliance assets — CE marking to EN 13168/EN 13964 (audited by Bureau Veritas), Cradle to Cradle Gold, FSC C115450, PEFC chain-of-custody, Danish Indoor Climate Labeling, and third-party-verified EPDs — which together constitute the core switching-cost moat in certified European construction. Sustainability credentials are increasingly central to the commercial proposition, with 98.3% of factory energy sourced from renewables as of 2025 and EPDs republished in August 2025.

Customer segments are deliberately diversified across education (schools, universities, daycare), commercial offices, sports and recreation (notably swimming pools, leveraging moisture resistance), hospitality, healthcare, defense/military barracks, and private residential. Documented reference projects include the Skolen ved Sundet school (Copenhagen), Bellahøj Svømmestadion swimming stadium, Merkur Andelskasse bank branch in Aarhus, and multiple award-winning private residences — illustrating deployment across public infrastructure, sports, financial services, and high-end residential. The company operates as a privately held Danish A/S with no disclosed external investors, parent company, or public shareholders.

Core offering

Troldtekt designs, manufactures, and sells cement-bonded wood wool acoustic panels for ceiling and wall cladding, including the core Troldtekt akustik, akustik Plus, ventilation, and agro lines, plus a Troldtekt design series of patterned variants, fire-rated A2 panels, and supporting track systems and accessories. The panels combine certified wood and cement (with an optional FUTURECEM low-CO2 cement) to deliver sound absorption, fire protection, moisture resistance, and design flexibility for new construction and renovation across residential, educational, commercial, sports, hospitality, healthcare, and defense buildings.

Product overview

Troldtekt is a Danish manufacturer of acoustic wood wool cement panels for ceiling and wall cladding. The product portfolio consists of three core acoustic panel lines (Troldtekt akustik, Troldtekt akustik Plus, and Troldtekt ventilation), supplemented by the Troldtekt design series offering aesthetic variations (line, v-line, tilt line, dots, curves, tiles, rhombe), and specialized solutions (Troldtekt agro, fire-rated A2 variants). Supporting products include ceiling track systems (C60, T24, T35), accessories (screws, paint, inspection hatches, brackets), and mounting/finishing tools. All products are based on the company's core technology combining certified wood and cement, with an option to use CO2-reduced FUTURECEM cement. The design solutions share acoustic performance while offering different visual patterns, while the Plus variants provide two-layer construction for retrofit applications.
