Using the indicator markings on the panel, screws are placed 12” o.c. along the InSoFast studs per code report. InSoFast panels are generally screwed in place, however, you may opt to use nail guns to install the panels and siding provided the temperature is above 60° F for the stud to accept nails. It is up to the contractor and/or building official to determine the suitability for the nails in regard to use, length, and spacing.
On the back of the panel, apply a 3/8″ bead of PL Premium 3X along the dove-tailed ribbing of each InSoFast stud. Rougher or uneven surfaces may require a thicker bead. Press panels firmly into place against the wall. On windy days, the panels may need supplemental bracing or mechanical attachment to secure the panels until the adhesive has set.
