Durable acoustic cladding of ceilings and walls

Troldtekt cement-bonded wood wool is a rugged and durable material. The setting and curing process transforms the cement in the panels into concrete and gives the material its strength. The natural properties of the wood make the material breathable and permit diffusion. Troldtekt panels are suitable for screw installation and are also easy to work with and cut.

Moisture-resistant
Troldtekt panels can absorb and release moisture and are therefore ideal for ceiling and wall cladding in wet rooms, such as bathrooms and swimming pool centres. Troldtekt panels can also be used outdoors, for example under overhangs. The material cannot rot and does not provide a breeding ground for fungi or other microorganisms.

Stable shape
Troldtekt panels have an extremely stable shape and retain their flatnes – even in moist environments. There is no warping over time. If the air humidity in a room changes by one percentage point, the panel dimensions only change by 0.005 per cent.

Ball impact certification

Troldtekt is ball impact tested in accordance with ‘Prüfung der Ballwurfsicherheit, DIN 18032 Teil 3, Sportshallen für Turnen und Spiele’ (requirements and testing of ball impact safety, DIN 18032, Part 3, sports facilities).

A wide range of constructions with Troldtekt are testet and approved for application as wall and ceiling in sports facilities and gyms where it is exposed to considerable impact when, for example, a handball strikes at high speed.

Ceiling and wall cladding in sports facilities and gymnasiums are exposed to stress from ball impacts.

In Germany, documentation is required for the ‘certification to withstand ball impact’ of the materials in accordance with ‘Prüfung der Ballwurfsicherheit, DIN 18032 Teil 3, Sportshallen für Turnen und Spiele’ (requirements and testing of ball impact safety, DIN 18032, Part 3, sports facilities). The tests are carried out at a laboratory in the facility for research and materials testing for the construction industry (Forschungs- und Materialprüfungsanstalt für das Bauwesen (FMPA)) at the Otto-Graf Institute at the University of Stuttgart. The CE standard for suspended ceilings, EN 13964, also includes ball impact certification as a parameter, and the German tests are performed accordingly. In accordance with EN 13964, Annex D, Impact resistance, Troldtekt is classified as class 1A.

A wide range of structures fitted with Troldtekt acoustic panels have been tested at the institute in Stuttgart and have been approved for use as ceiling and wall cladding in sports facilities. This applies to structures on wooden battens as well as structures suspended in C60 profile systems.

Ceiling cladding
A handball is thrown 36 times against the test ceiling at a velocity of 16.5 ± 0.8 m/s. The shots are thrown 2 × 12 times at an angle of 60° and 1 × 12 times at an angle of 90°.

Wall cladding
A handball is thrown 54 times against the test wall at a velocity of 22.5 ± 1.2 m/s. The shots are thrown 2 × 12 times at an angle of 45° and 1 × 30 times at an angle of 90°.
