Lay 2mm PE film for 10.5mm cork flooring

Hello everyone,

yesterday I installed the PE film required by the manufacturer for our cork floor (10.5mm construction from WICANDERS).

The film wrinkles a bit in certain spots and I wanted to ask whether this can actually be decisive for an uneven installation of the floor?

I really can’t imagine that such a thin film must/can lie 100% wrinkle-free on the floor – this is practically impossible when installing the film. The floor also has a certain weight of its own and presses the film down after the floating installation – or am I seeing something wrong here?

Hello questioner. To answer your question briefly: No, if there are small and unavoidable folds in the PE foil during installation, this will have no effect on the top surface. So you are correct! Regards: KlaRa
