Remodeling is a big job with a lot of demolition. To reduce the amount of demolition and waste InSoFast panels can be installed directly over drywall or plaster.
This application using the Flat Panel 2" or 2 1/2" used in this configuration with 1/2" drywall, very little interior space is lost.
Preparing the walls for installing the InSoFast Panels.
The wood frame stud layout is important to determine before the first panel is installed. There are several methods to locating your studs behind drywall from expensive electronic studs finders to simple magnets. Link to simple magnets. Similar to typical wood framing, InSoFast panel's studs are 16" on center to this is common to wood framing layouts. The panels can be trimmed and adjusted to align with the framing so then can be screwed to the walls.
*If the framing does not align the adhesive method can be used.
First Things First Prepare the wall.
Remove the window trim and sills, heating registers, and electrical covers from the wall and disconnect the power to the outlets.
Add an extension jamb to extend the window frame so that it will be flush with the top surface of the insulation panel.
To fasten the interior half of the jamb we used standard wood deck fasteners from ITW Buildex.
The window jambs are installed move onto the next step add a wall duct stack fitting to extend the forced air duct beyond the InSoFast.
Install an electrical box extension ring, commonly called an "add-a-depth-ring". Not to be confused with the Star Wars death star.
Cutting the panels to meet the wood stud layout;
After the layout is determined and the panels are cut to fit the wood stud layout it is helpful to pre-set screws into the panel.
Place your first panel in the corner.
Attach the panel to hold it in place.
Stacking the inter-locking panels;
The panels are designed to self-align and inter-lock so once the first row is in the panels are ready to stack.
Cutting around openings like windows leave a 1/4"- 1/2" gap this will later be air sealed with spray foam. InSoFast is rough carpentry not finished work. Dings dents and big cuts are okay.
When installing around a tight opening like this panel that is undercut set the panel on the tongue of the interlock and roll it up into place.
Install 2 screws per stud into each panel for a total of 6 screws per panel. A 3"- 3 1/2" wood screw works best.
Once the panels completely cover the wall you are ready for the next step.
Interior application of insulation over framed walls part 1
Most remodeling insulation projects will involve an intricate multiple step messy process: starting with the tearing off drywall, disposing of the drywall, installing the insulation in-between the framing. Anyone who has ever attempted a remodeling project like this can expect, Dust, Dirt, Noise and Disruption! Once completed only 75% of the wall has been insulated. That means a R-13 wall is really only an effective R-10 assembly. InSoFast's method of insulating will deliver better results. A low impact and highly beneficial method of updating and increasing comfort and livability for any room in your home. InSoFast is a One-Step solution combining an insulated stud that will bridge over framing's cold spots applied directly over existing drywall. This superior method of insulating with minimal disruption, will double the performance of your completed wall.

Unique Applications and Conditions
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) or about 6 panels for 48 square feet.
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.
