Estimating Panels

Estimating and ordering is simple measure and add together how many square feet of side wall framing that your container requires to complete the job. Divide the total wall (xx) footage by 36.67 sq-ft. this will determine the number of boxes needed. Round up to the next whole number. Don’t overestimate, cut studs, panels and inserts can be re-used.

    • One box of 5 (CX44 Insulated Panel = (36.67 sq-ft.)

Estimating Adhesive

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? 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)
