Do I need an expansion joint when gluing parquet?
With fully glued wood floors, it is usually not necessary to attach transition, end or adjustment profiles as an expansion joint. An expansion gap must only be maintained to fixed components and walls for acoustic reasons. This distance usually results in an expansion joint of approx. 10 mm between the wall and the first row of parquet (depending on the edge joint in the substructure), and a few millimetres for other components or adjacent solid floor coverings (e.g. tiles). At the end of installation, this expansion joint is sealed with acrylic in a matching colour, for example. If there are expansion joints in the substructure, these should also be taken into account during installation. Since the subfloor "works" at this point, there is a high probability that the parquet will shift in the long term. In this case, consult a professional installer on how the expansion joint must be transferred to the glued wood flooring.
