“Vapor Tight” vs. “Vapor Open” (7/20/21)

“Vapro tight vs. Vapor open

Construction projects which utilize a vapor impermeable wall assembly do not allow moisture to escape via vapor diffusion.  This science applies to both wood framed and cold-formed steel wall assemblies.  Recent research and construction defects have shown that moisture can be trapped by vapor impermeable systems.  Vapor impermeable assemblies are less tolerant of water intrusion.”
