Moisture barrier proven mold free

The high density polyethylene moisture barrier bonded to the underside of DRIcore subfloor panels is molded with dual wall cleats that are durable and act as a raised moisture barrier. Independent lab tests confirmed that the DRIcore polyethylene moisture barrier does not support the growth of mold. " The panels due indeed fit nice and tight with one another with really no seams at all to speak of, so I assume the VB is relatively contiguous and I don't need one for the laminate.
