Snap a straight line for the starter track or metal flashing at the bottom of the wall so that the bottom of the InSoFast panel is not exposed.
The word “InSoFast” must face outward toward the installer with the exposed ribbed side of the studs going against the wall or sheathing. No black strips will be visible. (photo right)
InSoFast panels are installed with the 4’ width dimension running horizontally. The 2’ height dimension, studs and moisture control channels all run vertically.
The top edge of the panel features the interlocking tongue and the bottom edge features the interlocking groove.
When cutting panels for corners, openings, and penetrations, leave a ¼” gap to fill with foam sealant.
For easier installation, do not install the upper row of fasteners in the InSoFast panel until the panel above has been set in place.
