Wicanders as well as any other floating cork floors require a moisture barrier over concrete to prevent moisture from absorbing into the bottom of the cork. The film must be a minimum thickness of 0.2 mm or (6 mil). The MP Global Moisture Block meets these requirements and is NWFA (National Wood Flooring Association) approved. It comes in 100 SF rolls and requires no tape. Underlayment can also be used if desired. They are typically 1/8" thick and add some additional thermal and acoustical insulation. They are also softer to walk on. Our MP Global QuietWalk Plus is a vapor barrier and underlayment all in one and satisfies the above requirements as well. It has zero VOCs and is made with recycled content. We have it made specially for us without any biocides, fungicides or antimicrobials.
