one perm) and addresses vapor drive from below. With the impermeable rigid insulation, even relatively impermeable ground coverings such as vinyl flooring and polyurethane-coated Wooden flooring will get the job done. The circulation of vapor in the assembly (vapor travel) is below the circulation of vapor out in the assembly, even with fairly impermeable floor coverings. The rigid insulation needs to be set up airtight. The seams must be sealed with foil tape.
