How to Install CX44 Panels

The InSoFast CX Container Panel is designed for the side walls of most shipping containers. The CX panels are set up for an 11" repeating pattern of the corrugation and the panel size is 44" x 24". They are installed horizontally with the studs running vertically.Lay out the first row of CX panels to determine the fit to the container. Variations in the corrugations may require the panels to be trimmed or spaced out slightly. If the panels need to be adjusted, it is best to then stack bond the panels instead of installing in a running bond pattern. Leave a 1/4" gap to allow for spray foam sealant.

Before You Glue

Dry fit and adjust your panels to fit. Use a razor blade knife to fit around cargo hooks, dents, and weld seams.

Place a 3/8" bead of adhesive on the backside of the CX44 panel.

Loctite PL Premium 3x Adhesive

  • 1 large 28-fl oz / 828 mL tube = 18 (24" studs or inserts)
    • CX 44 (22 panels with 2 studs each plus 8 end wall edges) = 52
    • 52 ÷ 18 = 3 tubes of the adhesive

For example for one side wall of a 20' standard height shipping container you will need approximately 3 tubes of the adhesive. Additionally you will use more glue around openings like windows and doors.  

PL Premium 3x adhesive is applied in a ⅜" bead on the backside of the studs which have the ribbed surfaces. It is important that there is enough adhesive to squish into the dovetails on the back side of the stud.  To verify that enough adhesive is used, press the panel into place. Pull the panel back and check to see if the adhesive has spread out the width of the stud. It is normal for the panel to "float out" from the side of the container when it is accommodating irregularities in the container walls. Additional adhesive may be necessary in some areas. If you find an area that has not bonded to the container, simply drill a hole through the foam and inject additional adhesive.

Add a 3/8" bead of adhesive to the cut end of the panels

Since there is no stud at the cut ends of the panels, an additional bead of PL Premium 3x is applied at the start and end of each wall.  If you find an area that has not bonded to the container, simply drill a hole through the foam and inject additional adhesive.

Air seal the bottom of the first row of panels. 

It is important to seal the bottom of the first row of panels. Apply a continuous bead of spray foam or adhesive along the bottom of the side wall of the container.

Air sealing the rows horizontally.

Air Seal the panels horizontal rows every 2' with sprayfoam adhesive.

At the top of the second row, run a bead of spray foam on the back side of the panel or directly on the container wall. We recommend sealing the horizontal rows every 2’ to prevent air movement behind the panels. 

Install CX Panels in a running bond pattern, (stagger joints like brick work.) To start the second row, cut a panel in the center with a long snap off blade utility knife. This will start the off set running bond or staggered pattern.
