Metal roof vapor barrier insulation.

Ft 72 inch 6 ft. After the insulation is in place you will want to add a vapor retarder sometimes called a vapor barrier if you need one. In fact rhino s vapor retarder rates 300 stronger than the vinyl barriers typically offered by most metal building companies. A roof design that includes an adhered roof membrane with multiple layers of insulation with board joints offset and staggered over a vapor retarder air barrier helps lower the risk that air and the moisture it carries will infiltrate the roof system.

Fiberglass and other traditional insulations for metal buildings resist heat loss by conduction and convection but has little effect on radiant heat gain loss. Not every wall does. Felt underlayment provides little resistance to air and moisture vapor migration and does not serve as an effective air barrier. Architectural metal roofs with felt underlayment are best suited for buildings with proper slope and low moisture loads in dry or arid climates.

Insulation and vapor barrier metal roofs and buildings require specific insulation and vapor barrier to meet the demands of condensation and breathability. A vapor retarder is a material used to prevent water vapor from diffusing into the wall ceiling or floor during the cold winter. That reduction of air and moisture infiltration can then help improve roof longevity. The most common types of metal building insulation are radiant barrier fiberglass insulation rigid foam insulation and spray foam insulation.

Fiberglass batts or glass mineral wool metal roof insulation the most common material used for an insulating metal roof is fiberglass batts or glass mineral wool.
