The Endwall of the shipping container is a two step process and is insulated with Endwall Inserts either the UX 2.0 or EX 2.5 flat panel. These panels are 48″ x 24″ and are installed on end wall.
Install either the UX 2.0 or EXi 2.5 Flat Panels
UX 2.0 Flat Panels
2″ thick of closed-cell, injection-molded EPS foam body achieves R-8.5 insulation The UX2.0 is our thinnest flat profile panel, optimized for flat surface interior finishing. The UX 2.0 will work on floors, walls, ceiling and can be adapted for shipping container construction or other unique applications. It is a good choice as a base panel for the InSoFast PLUS when higher R-Value is needed.
EXi 2.5 Flat Panels
2 1/2″ thick of closed-cell, injection-molded EPS foam body achieves R-10 insulation. The EXi Flat Panel is optimized for interior finishing. The panel will work on floors, walls, ceiling and can be adapted for shipping container construction or other unique applications. It is a good choice as a base panel for the InSoFast PLUS when higher R-Value is needed.
First Things First
Safety Precaution: Cut out all openings in the container and complete any welding, cutting or grinding operations prior to installing InSoFast panels. Do not expose the foam insulation or plastic studs of InSoFast panels to the flames, heat or sparks generated by welding, grinding or cutting on the steel container after panels have been installed.
See this page for in depth instruction for installing wood bucks. MORE
Determine your window layout first. We suggest that you adjust your openings to the right or left up and down to simplify other steps later on. If you invested in a sample kit use the side wall insert to help you mark your layout lines.To fasten the interior half of the buck we used special fasteners fro ITW with a drill bit and metal wings that over drill the wood then break-off to allow the screw to anchor itself to the steel container wall.
The window bucks are complete and ready to finish. Next step is to insulate the interior walls with the Sidewall Inserts and the UX2.0 Flat panels.
Start with a continuous bead of spray foam or adhesive along the bottom of the end wall of the container. Next lay a bead of adhesive in an “S” pattern down the center of the backside of the End Wall Insert. Set the inserts into the lower half of the end wall corrugations. Once in place seal the top of the insert with a bead of spray foam. Continue to cut, fit and glue all the insert into the end wall. Spray foam and seal all your work.
Add a bead of PL Premium 3x along the corner where the first row of panels meet the corner of the container.
We recommend installing panels standing on end with the embedded studs running perpendicular to a shipping containers corrugated ribs. The goal is to provide as much contact between the studs and steel in order to maximize the holding power of the studs.
You may want to trim the end of the UX or EX panel to “move” the stud down closer to the floor allowing baseboard to be attached. On the back of the panel, run a 3/8″ bead of adhesive along dove-tailed ribbing of each stud.
For a standard 8’ high container, the panels can be installed in a stacked method or a running bond pattern. The running bond pattern works better to eliminate waste on a 9’ high container. Use the cut off end of the top panel to start the next column.
Seal the gaps at the tops and edges of the corners with spray foam.
We do not recommend installing UX 2.0 or EX 2.5 panels without the Inserts. The Inserts are needed to prevent convective looping behind the wall. If the end wall inserts are not used, seal the corrugation with spray foam at every 4’ height horizontally to minimize the convective loop.
InSoFast Plus Method
Need a higher R-value? No Problem! Start with a base of InSoFast continuous insulation panels they are feature-rich and easy to install. Then add rigid foam insulation over top of InSoFast panels.
