Hello,
we are having floating cork flooring installed. It is a new build, and the screed has passed the CM measurement test, so it is dry enough for installation. The floor installer is not using a PE foil as a vapor barrier, contrary to the manufacturer’s instructions. We find this a bit odd, since the installation guide clearly states that a vapor barrier is always required on mineral substrates like screeds.
The installer argues that this is not necessary for new builds, but rather for older buildings and those without basements, even though new screeds generally still contain more residual moisture.
How critical do you think this is, and should one insist on strictly following the installation instructions?
