A continuous vapor barrier can be achieved with a single layer of insulation in a metal building. Fiberglass insulation rolls with a vapor barrier pre-applied are installed above the roof purlins or wall girts before the metal roof or wall panels are applied. This application gives the building a thermal break between the exterior metal on the building and the interior metal framing. Up to 6″ of fiberglass can be installed which offers a rating of R-19.

The insulations rolls are precut to fit the building’s dimensions before they are laminated with the vapor barrier. Tabs are provided to create a continuous vapor barrier by attaching to the next piece of insulation.
