1 perm) and addresses vapor travel from underneath. With the impermeable rigid insulation, even reasonably impermeable floor coverings which include vinyl flooring and polyurethane-coated Wooden flooring will function. The flow of vapor in the assembly (vapor generate) is less than the stream of vapor out in the assembly, even with fairly impermeable flooring coverings. The rigid insulation needs to be mounted airtight. The seams must be sealed with foil tape.
Could be combined with other techniques to fulfill exclusive or complicated job needs cost-effectively and proficiently
