Hello, we are having floating cork installed. It is a new building, the screed has passed the CM test, so it is sufficiently dry for installation. Contrary to the manufacturer's instructions, the floor installer does not use a PE foil as a vapor barrier. We find this a bit strange, especially since the installation instructions state that a vapor barrier is always necessary on mineral floors such as screeds. The floor installer says that this is not necessary in new buildings, rather in old buildings and non-basement buildings, although screeds in new buildings generally contain more residual moisture. How critical do you see this, and should one insist on adhering to the installation instructions here?
