Estimating Inserts

Estimating and ordering is simple measure and add together how many 20′ long 8′ wide ceiling areas you need to infill with the inserts.  Don’t overestimate, cut inserts can be re-used.

Inserts fill every indented void.  One insert box will do a standard 20′ IEU container depending on your specific layout. 

  • 1 box (ins-ceil-56 = 56 pcs.) = (28) 8′ long inserts

Green Guard Certified Adhesive:

In Canada the Glue is LePage PL Premium

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 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. If you are doing it 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-LP 46 (46 studs) = 46
  • 46 ÷ 18 = 2 1/2 tubes of the adhesive
  • I-SWI (30) = 1 tube of the adhesive

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.
