"That's a nifty one! I'd much rather have installed this, vs. re-taping and floating the drywall in my last house's utility room. One major consideration, though, is the potential for condensation and mold growth if these panels are installed on the inward faces of exterior walls. In humid climates, where water vapor tends to move through exterior wall assemblies from the wetter outside towards the drier inside, mounting a vapor-impermeable material on an exterior wall creates a surface where vapor can condense and increase mold growth potential. This is very common in schools, for example, when a teacher hangs a laminated poster on an exterior wall, or in commercial kitchen or utility spaces when plastic wall panels are used over drywall as easy-to-clean finishes.  Doesn't have to be an exterior wall, either; any wall assembly with a significant difference in relative humidity on either side will tend to experience vapor movement from the high-humidity side to the low-humidity side. So, spaces like natatoriums, autoclave rooms in hospitals, spaces adjacent to locker rooms, etc. can all experience this effect, and it's exactly these spaces where a PVC wall finish would be most useful (easier to sanitize / keep clean, tends to be waterproof, etc.). Extensive knowledge on this over for residential at finehomebuilding.com, the Journal of Light Construction, Green Building Alliance, or IIBEC / AABA / ASHRAE for commercial. "
