In VOB Part C DIN 18365 “Floor covering work”, the associated commentary as well as additional information sheets and guidelines, it is stipulated that the room air temperature must not fall below 18 ° C. In addition, the relative humidity in the room should be between 40 and 65%. Under these climatic conditions, installation materials and the textile floor covering must be tempered/air-conditioned. High room air temperatures lead to changed reaction times and drying processes when processing the laying materials and can lead to changes in the dimensions of the floor covering. We recommend not exceeding a room air temperature of 26 ° C. The floor coverings must be air-conditioned for at least 24-48 hours in the unrolled state (sheet goods) or lying on a flat surface (modules) in the rooms intended for installation. The covering must be protected from direct sunlight or other heat effects until the laying work has been completed.
The generally necessary acclimatization of the floor coverings and the setting and drying times of the laying materials and the specified room climatic conditions must be observed up to 3 days before, during and up to 7 days after completion of the flooring installation. The client/user is responsible for creating and complying with the aforementioned indoor climate requirements.
