LowPro and Inserts Sidewall Installation

Installing CX LowPro Insulated Studs and Inserts

Before You Glue;

Why you would use LowPro Insulated Studs

CX LowPro a hybrid solution for insulating containers. The CX-LP studs are ideally suited for intermodal container conversions where thin wall insulation and framing is the primary concern. If you are not planning to embed services like wiring in the wall. The stud are small making them easier to handle and modify around dings and dents of older containers.

Before you Glue

The LowPro insulated studs are designed for the side walls of  shipping containers. The CX-LP fits into this container's corrugations adhering to the industry standard of 11" on center, repeating pattern of the corrugated sidewall.  This spacing conflicts with standard 4' x 8' construction !  The LowPro stud spacing is either 11" or 22" on center.  THIS EFFECTS the finish materials installation methods. (E.G. a sheet of drywall 48" x 96",  22" on center does not divide evenly into 48 or 96.) The fastening and adhesive patterns will change and finish material waste should be considered. 

First Things First

Safety Precaution: Cut out all openings in the container and complete any welding, cutting or grinding operations prior to installing InSoFast products. Do not expose the foam insulation or plastic studs to the flames, heat or sparks generated by welding, grinding or cutting on the steel container after InSoFast materials have been installed. 

Dry fit and adjust your studs and inserts to fit before you glue. Use a razor blade knife to fit around cargo hooks, dents, and weld seams. Leave a 1/4" gap to allow for spray foam sealant.

Installing a Wood Buck into a Container;
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.


LowPro Insulated Studs Interior application

CX LowPro Insulated Studs Interior application

The long sidewalls of the shipping container using the LowPro Stud is a three step process and is insulated with Sidewall Inserts and locally sourced 3/4" thick sheet foam insulation.LowPro interior applicationThe adhesive applied CX-LP eliminates the hundreds of holes associated with shipping container or sea can modifications. The CX LowPro stud is part of a assembly to work with the Side Walls Inserts. The corrugation infills are typically placed on either 11 - 22 inches on center in an alternating pattern with the (SWI) side wall inserts. The CX-LP insulated infill framing is ideally suited for container conversions in commercial, residential, industrial, interior or exterior applications where thin wall insulation and framing is the primary concern.  LowPro used in this configuration with 1/2" thick drywall only  1 1/4" of interior space is lost.

Installing the LowPro Insulated Studs

Install the LowPro Insulated StudsApply a 3/8" bead of Loctite PL Premium 3x construction adhesive horizontally across the top and bottom then directly over the ribbed surface of the backside of the stud to form "I" pattern.

The LowPro studs can be cut to fit with regular wood working tools or razor knifes.

Installing infill insulation in the corner

Install infill insulation in the corner.

The inside corner can be filled with 1 1/2" thick board stock insulation from a local lumber supplier. Alternatively a set of the LowPro studs or the sidewall inserts can be trimmed to fit. 

Installing the sidewall inserts

Install the sidewall inserts.

Place a bead of adhesive in an “S” pattern down the center of the backside of the sidewall insert. Set the inserts into the lower half of the sidewall 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 onto the sidewall corrugations. Spray foam and seal all your work.

Installing the the locally sourced 3/4" sheet insulation

Install the the locally sourced 3/4" sheet insulation.

When the LowPro Studs are installed in an alternating pattern of 22" on center, the sheet foam is cut from a 48" x 96" (3/4") into 16" wide panels.

Insert 16” sheet foam between the LowPro Inserts. Use 5” wide sheet foam when LowPro is installed in every corrugation

Optionally when the LowPro Studs are place in an alternating pattern of 11" on center, the sheet foam is cut from a 48" x 96" (3/4") into 5" wide panels.

It is highly recommended that the 3 components be install at the same time. Once install tamp the panels with a straight edge like a 2x4 lumber to make sure that the wall is level and flat.

      • One box of the CX-LP 46 Insulated studs will do 92 lineal feet of framing.   
        • One 20' container side wall would need 44 pcs, of CX LowPros insulated studs and 20 pcs. of the Side Wall Inserts to do one side.
        • One box of Side Wall Inserts has 30 pcs. that are 48 inches long or will cover 112 Lineal feet of corrugation in-fill.

The high-strength co-polymer plastic studs on 11 or 22-inches centers provide a positive attachment stud for finishing the container. The ribbed dovetails surface provides for adhesive applications against the metal surfaces.
