  • We also know that air leakage can carry far more water vapor into the roof system than moisture diffusion through a retarder 1 . (buildings.com)
  • As a roof system, SPF is highly impermeable, but as an air barrier, it also forms tight flashing seals at pipe penetrations, curbs, and walls. (buildings.com)
