Storage & acclimatisation of Troldtekt®


It is important to note that Troldtekt is a natural material and the very nature of the material composition – wood wool and cement – will incur small variations in the panels. Panel dimensions and weights remain inside the tolerance indicated at 23 +/- 2°C and 50 +/- 5% relative humidity. However, inappropriate storage and a lack of acclimatisation may alter panel dimension and weight. It is therefore important that you observe the installation, storage and acclimatisation instructions carefully.

Before installation of Troldtekt®

It is important that the Troldtekt panels are stored horizontally with proper support, e.g. on pallets or battens.

Outdoor storage

If it is necessary to store Troldtekt panels outdoors, we generally recommend that you protect the panels using a tarpaulin or similar. Please note that outdoor storage should be as brief as possible.

Indoor storage

If you store Troldtekt panels indoors, you must remove any packaging, as condensation could otherwise form within the packaging.

Acclimatisation will not start until the packaging is removed and the panels are ‘battened up’. Care should be taken to protect stored Troldtekt panels from moisture, direct heat and dust.

Be careful to protect the panels from dust throughout the construction period.


Troldtekt panels should acclimatise for a minimum of 2 weeks and a maximum of 8 weeks before installation.

It is important that the Troldtekt panels are allowed to acclimatise prior to installation. Acclimatisation means that the panels must adapt to the temperature and humidity that is expected to be in the room when the building starts being used. Under these conditions, it is recommended to acclimatise the panels for 2 weeks or more before installation. The time for acclimatisation depends on the relative humidity and the air change in the room.

Optimum acclimatisation is achieved by ‘battening up the panels’, i.e. by placing battens between the panels and ensuring good ventilation in the room in question. Troldtekt is a purely natural material consisting of approx. 50% wood, and the panels will therefore ‘work’ to achieve the same temperature and humidity level as their surroundings – like, e.g. wooden floors do. You should therefore not start installing Troldtekt until the building is completely sealed and the room reaches a temperature and humidity as in the use phase. Troldtekt panels have undergone a drying process before leaving the factory in Troldhede, but during transport or storage, the panels may absorb moisture again. If you install the panels without acclimatising first, the panels are at risk of shrinking when they dry, which may result in small cracks. If the panels absorb moisture after installation, they will merely push into each other. There is consequently no risk of the panels expanding so much so that they push to other building parts.

Troldtekt panels should also be acclimatised when installed in wet rooms or outdoors.


DanSticks® for battening

DanSticks® by Troldtekt are battens for battening all Troldtekt acoustic panels. The battens ensure easy and stable acclimatisation of the acoustic panels before installation.

DanSticks are made of recyclable plastic, they are easy to clean and can be used again and again.
