Outside Corners Installation Options

Outside Corners

Corner with Sheet Metal Backer

Overlap the panels past the corner by the thickness of the panel (i.e. 2½” for EXe 2.5) creating an overlapping butt joint. Leave a ¼” gap at the butt joint for foam sealant. Corner posts can be attached with a 4” screws directly back to the framing when an InSoFast stud is not located near enough to the corner for siding attachment. Sheet metal flashing may be added behind the corner post for siding fastening at the corner post.

Sheetmetal Backer

TIP: Use Loctite Pl Premium 3x to adhere the sheet metal corner to the InSoFast panel and duct tape to hold corner in place until the adhesive cures.

Corner with Wood Backing

Another option is to install 2x dimensional lumber with 1” foam board added to provide a solid 2-1/2” thick backing as needed. This can be done prior to installing or after installing the InSoFast panels.
This application  1" thick silver foiled foam panel was added to the wall sheathing then the 2x corner backing material was added on top.

Head Jamb Flashing

Head Jamb Flashing Detail;


Side Jamb Flashing

Window Side Jamb


The side jamb is installed with the nailing flange flush with the front face of the InSoFast panels. Typically an extension jamb is used to bring the window flush with the exterior finished surface. Install window and flashings as per window manufacturer’s installation instructions prior to installing InSoFast panels.

Sill Flashing

Typical Sill Flashing


An inset window is installed with the nailing flange flush to the exterior sheathing layer of the wall. It requires sill and jamb extensions for the exterior. Install window and flashings as per window manufacturer’s installation instructions prior to installing InSoFast panels.

Other Through-Wall Penetrations

Mechanical penetrations are treated as they would be for typical construction. All through-wall penetrations should be installed and sealed back to the WRB layer before the InSoFast panels are installed. Install penetrations to manufacturer’s installation instructions. Cut and fit the InSoFast panel around the penetration, leaving a ¼” gap. Fill the gap between the penetration and the InSoFast panel with a foam sealant.

Installing Exterior Finishes - Cold Weather Installation

If you opt to use nail guns to install InSoFast panels and/or siding, it is only recommended when temperatures are above 60° F. Smaller nail size and shank diameter will perform better at lower temperatures. It is up to the contractor, and/or building official to determine the suitability for the use of nails when installing siding. It is important for the contractor to verify that the fasteners do not crack the stud and that they are not over-driven or under-driven into the stud.  In cold weather to keep working you can hand nail the siding or for cement board applications switch to ITW Buildex Product Report: Stucco/Cement Board Applications (Rock On Fasteners) (PDF, 127kb)

The InSoFast Panel features built-in drainage channels that are specifically designed to direct the flow of moisture out of the wall.


Physical Properties

Insulated Stud's Features

The InSoFast panel studs provide a simplified approach to wall assembly. The InSoFast stud are injection-molded high-strength recycled polypropylene plastic. Next a special co-molding process expands the foam insulation around the studs forming one solid panel. The studs provide a structural attachment point to the substrate and for the specified finishes. For More Information:
