Station 8: Sheathing & Barrier Application

Station 8, the assembled panels are brought to the Sheathing and Barrier Application station. Here, we complete the enclosure layers of the panel. First, panels are fitted with sheathing – this could be exterior grade OSB or plywood, gypsum-based sheathing, like DensGlass, or other exterior sheathing, depending on the wall system specified. Large sheets of sheathing are cut to size and fastened to the steel framing of the panel, with self-tapping screws. The screws are driven at the proper spacing to meet structural and shear requirements. Installing sheathing in the factory ensures precise placement and allows us to use collated screw guns for speed and consistency. It also means we can achieve a straighter, well-fastened wall than might be done in the field, as the panel is flat on a table and accessible from all sides.

Next, if the wall system requires it, we apply the weather-resistant barrier (WRB) or air barrier (AB) over the sheathing. This may involve applying tape or a fluid-applied sealant to the joints and fasteners of a sheathing board with an integrated WRB/AB, such as DensElement or ExoAir. Alternatively, we might roll on a liquid-applied membrane across the entire exterior surface of a sheathed panel. Our factory-installed air and moisture barriers provide a significant advantage. Our technicians meticulously seal every penetration and opening in a controlled environment. If specified, we also integrate additional elements at this stage: z-girt cladding supports can be pre-attached through the sheathing, and insulation boards can be added to panels requiring continuous insulation. Each panel’s build sheet undergoes a final check after sheathing WRB/AB application to ensure all details are meticulously completed.

This station reinforces the weather independence and quality of our prefabrication system. While on a traditional build you’d need a weather window to sheath and apply the WRB/AB to the building, here every panel is weather-protected at the factory. The result is consistent performance – every panel has the proper overlap, taping, and materials installed exactly as designed, contributing to the overall building’s energy efficiency and moisture protection. This step will shorten on-site construction time since the field crew doesn’t have to spend time in lifts applying the WRB/AB – it’s handled here with precision.
