How to install CX44 panels in corners.
The cuts for the corners can be used on the other side of the wall.
The corners should look like this when completed. Fill all open spaces/air gaps with spray foam as needed.
Here we used pink foam to illustrate corner fill foam by others.
Container side walls can vary slightly in length. We call this weld seam drift. Always check for proper fit and drift and adjust the corner panel cut length layout accordingly. The end cuts and scrap can be trimmed to fit and fill changes in container geometry, glue the pieces back together.
No stud in the corners
Or yes we do not have a stud in the inside corner. A solid wall the corner is already supported. There is no need to panic. You can glue the finish material the panel or glue a sheet metal angle for screw attachment.
Precaution: 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. Cut out all openings in the container and complete any welding, cutting or grinding operations prior to installing InSoFast panels.
Attaching Drywall to inside or outside Corners or prepare-corner-for-drywall. Corner angle is a multipurpose 90˚ galvanized angle used in dozens of framing applications. Available in roofing/flashing section of home improvement stores or drywall supply yards. Some of the most common applications include lapped framing conditions, offset framing, floor and ceiling runner, gypsum drywall partitions.
Place beads of adhesive on the back side of 3″ x 3″ – 25 ga. sheet metal corner angle. Press into place on corner. Hold in place with duct tape if necessary. Hang drywall using all-purpose drywall screws into InSoFast studs and into sheet metal corner angle. Install metal drywall corner bead using all-purpose drywall screws.

The Recommended Adhesive:
Loctite PL Premium
Green Guard Certified Adhesive:
One of the many reasons we recommend Loctite PL Premium is it has the GREENGUARD Certification. It is important to us that you use an adhesive that has low chemical emissions, you are building in an airtight shipping container, improving the quality of the air you breath is kind of important.
InSoFast panels were designed with simplicity in mind and we would argue that gluing them is not only the easiest method of installation but often the most effective. Third-party testing has shown the adhesive bond strength of our studs to have 108psi of holding power. This means each adhered panel is capable of holding over 5,000lbs!
In Canada the Glue is LePage PL Premium
Testing was conducted using Loctite PL Premium’s 3X Stronger Construction Adhesive, (in Canada it is marketed under the LePage PL Premium brand,) on clean concrete surfaces. It is the only adhesive we have tested. Other formulas and brands may not work as expected.
Estimating Adhesive Quantity
Estimating the amount of adhesive YOU will use has variables beyond our control like condition of your walls and how accurate are you with a glue gun? The example below is for one side wall of a 20' standard height shipping container you will need approximately 3 tubes of the adhesive. That is in a perfect world. PL Premium 3x adhesive is applied in a ⅜" bead on the backside of the studs onto the ribbed surfaces. We realize that a 3/8" bead of glue is very subjective. It is important that there is enough adhesive to squish the dovetails on the back side of the stud when pressed to the container wall. Adhesive follows the "Goldie Locks rule, too much, too little, and just right. If you are doing just right you can expect that 1 large 28-fl oz tube will cover 18 of our 24" long studs or enough glue at a 3/8" bead to cover 36 foot long bead of glue.
Additionally you will have to estimate for glue around openings like windows and doors.
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
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 beyond the full 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.

Important Notice: Container Surface Temperature Applications
When bonding EPS and XPS foam insulation, use above 40°F (4°C) and avoid cure and surface temperatures above 90°F (32°C). Surfaces must be clean, dry and free of frost, grease, dust and other contaminants. Pre-fit all materials and protect finished surfaces. If using cartridge format, cut nozzle at a 45° angle to desired bead size and puncture inner seal. Be very careful not to allow Loctite® PL® Premium to cure on a finished surface.
Cold Weather Tips:
Heating the interior of the container will not be sufficient for the adhesive to cure because the insulation panels will not allow heat to transfer to the container surface. It is recommended to either move the container to a heated area or tent and heat the exterior until the adhesive has cured.
The interior of the container can be heated until the adhesive has cured.
Interior and Exterior Installation
Install the exterior panels first while heating the interior. Allow adhesive to cure before installing interior insulation.
Wear gloves. Cured adhesive on bare skin will not come off immediately with washing and will cause skin to darken. Cured adhesive and discoloration will come off in about 3 days.
Clean tools and uncured adhesive residue immediately with mineral spirits in a well-ventilated area to the outdoors. Remove cured adhesive by carefully scraping with a sharp-edged tool.

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.
