Groove acoustic panels are made of medium density fiberboard (MDF) material that expands depending onclimate conditions. For this reason, it is important to leave a distance, called dilatation joint,between the perimeter of the wooden panelling and walls and other fixed objects in the premise.
During summer season, panels expand considerably due to high air humidity and temperature.
A minimum dilatation joint of 8mm (1) must be guaranteed. In case of wide surfaces, this joint has to be increased. As a general rule, a minimum of 1,5mm of joint for each lineal meter of panelling is needed at each side of the room. Example: a room of 5m in width needs a minimum of 8 mm of dilatation joint at each side.
Note: minimum 15 mm with a relative air humidity > 65%.
Although the material have contact at only one side with a wall or other fixed objects, it is possible that
panelling goes off. Dilatation joints are covered with skirting boards or special profiles.
