Vapor impermeable insulation facing construction

摘要

Vapor impermeable reinforced facing material is cut into longitudinal rectangular sheets and further reinforced by metal straps sealed in the facing material along the edges of the sheets, the sheets are attached in an overlapping manner to ceiling purlins by screws drilled into the purlins through the metal reinforcing straps which run down the longitudinal edges of the sheets. The ends of the sheets are attached to the I-beams, which support the ends of the purlins, by screws drilled into the beams through metal reinforcing straps which run along the transverse edges of the sheets.
