Apply Exterior Sheathing and House Wrap

What happens here

After the structural shell is complete, OSB (Oriented Strand Board) sheathing is attached to the exterior walls using a nail gun or screws. This creates a solid layer over the wall studs. A weather-resistive barrier, identified as 'Lowe's' brand house wrap, is then applied over the OSB sheathing. This wrap is crucial for protecting the sauna from moisture infiltration and improving energy efficiency by reducing air leakage. Openings for the door and any windows are carefully cut out of the house wrap using a utility knife.
