SOPREMA’s SOPRASEAL® Xpress G air and vapor barrier was ideal for this project. The exterior grade, inorganic faced gypsum board with an air and vapor barrier factory applied to the exterior surface, is the first and only ABAA evaluated assembly. SOPRASEAL® Xpress G boards are mechanically fastened to the structure using corrosion resistant SOPRASEAL® Xpress G Screws. A 6 inch self-adhered strip of SOPRASEAL® Stick 1100T is then installed over all board joints.

Holiday Inn Express – Medina, Ohio

SOPREMA®’s SOPRASEAL® Stick VP self-adhered vapor-permeable air barrier membrane was installed to ensure a continuous air barrier with no moisture infiltration for this wall assembly requiring a “breathable” characteristic. It creates a solid barrier against air infiltration and exfiltration, which minimizes associated energy loss and condensation problems.
