InSoFast Intersecting Walls

Install all of the InSoFast panels around the perimeter walls before building interior partition walls. Butt intersecting wall stud up to the InSoFast panels. Apply a bead of construction adhesive to the backside of the stud where it will come in contact with the InSoFast panels. Note your stud is fastened at the bottom plate and top plate.

If you did not adhere the intersecting wall stud to the InSoFast panels, use a concrete screw to connect the stud through the InSoFast panel into the concrete. It is important to remember that intersecting walls normally will be attached to the floor and ceiling so attaching the intersecting InSoFast panel is actually optional.

• • Recommended Method

Ensure that your cornered insulation panels are solid-backed by running a bead of adhesive along the panel (foam or stud) 2″ from the corner. Just before installing drywall, place a bead of adhesive on the foam near the corner. The drywall is bonded to the foam and the foam has been bonded to the concrete.

• • Option 1

When installing drywall, float the corners by screwing drywall into nearest attachment studs. This is a common practice for professional drywall installers because the InSoFast panels provide solid backing for the drywall.

• • Option 2

Place a bead of adhesive approximately 1″ from each side of the corner. Press 2″ x 2″ – 25 ga. sheet metal angle into adhesive. Attach drywall by screwing into the metal corner angle. Nail into intersecting stud. Attach drywall by screwing into the metal corner angle.
