Insulated StudsWe understand the initial concerns people have in learning our panels' structural stud framing is hidden...and that it's designed to be glued, screwed, or nailed to almost any surface. It's no small matter,-to perfect the multiple engineered features that make our panels so dependable, including the stud load capacity.
The Insulated Stud
The InSoFast panel studs provide a simplified approach to wall assembly. The InSoFast stud are injection-molded high-strength recycled polypropylene plastic. Next a special co-molding process expands the foam insulation around the studs forming one solid panel. The studs provide a structural attachment point to the substrate and for the specified finishes.
Reduces Construction Steps
One Part Not So Many Pieces
InSoFast panels reduce the complication of building an exterior wall assembly with an all-in-one rainscreen and insulation solution.
- Simple to install
- Molded into panel
- Stud framing included attach any finish
- Why handle all those parts?
- Why work so hard?
The easiest way to install a continuous insulated wall system.
The back surface of the stud features ribbed dovetails for adhesive application. The front surface is flat and designed to be nailed or screwed. The stud's face surface is either exposed or embedded 1/2" under the foam with indicator lines to mark their location. The recessed attachment notch on the stud keeps the screw head flush for installation ease of the finishing material.
Cast in Place-Not Glued
The glue does not stick to our polypropylene stud?
If you read the adhesives manufacturer's application information it states that the glue will not stick to polypropylene and our stud is made from polypropylene. The glue bonds to steel, wood, concrete and many other materials at many 100's of pounds of pull-off.
The design of the dovetail glue strip accounts for this non stickiness. The polyurethane adhesive expands around dovetailed "T" strip on the back side of the stud and as it cures it will (harden) cast-in-place the InSoFast stud. This cast-in-place function is one of our most important patent claims.

The minimum embedment requirement for concrete or concrete/cinder block is 1" and the maximum embedment is 1-3/4". Either length fastener will work to fasten our 2" thick stud to concrete.
How things stay in place?
The information below is an in-depth examination of the numbers behind our test reports. We'll explain how strength is determined in construction, draw comparisons to traditional materials and describe how you can achieve the best performance from our studs.
Our panels are made of two major materials: EPS foam and polypropylene plastic. The EPS foam forms the body of the panel and the stud acts like a regular studs when it comes to attaching finish materials, siding, stucco, stone, or cabinets and TVs. The embedded studs can be nailed, screwed, and glued. The studs do not split, rot, rust, or lose strength over time.
What metrics are used to determine strength in the InSoFast stud?
The independent Stork Twin City Testing Corporation measured adhesive capacities in their report. We received a Technical Evaluation Report from Intertek, a leading quality assurance testing corporation. Among other things, the report includes measurements on mechanical (screw and nail) capacities.
The reports focuses on two specific metrics for testing stud strength, Withdrawal and Lateral Strength. Withdrawal Strength is the capacity of the stud to hold weight without pulling the screw directly out of the material. Lateral Strength, or Shear Strength is the capacity of the stud to hold weight.
|#6 1¼in Standard Drywall Screws Pull Out (Fastener Withdrawal)||D1761-06||325.4 lb/ft|
|#6 1¼in Standard Drywall Screws Shear (Lateral Screw Resistance)||D1761-06||470.6 lb/ft|
|Adhesion of PL Premium Adhesive and Stud (Peak Stress)||D4541-02||108psi (972ps/lf)|
Double Thermal Disconnect
The panel provides a thermal and moisture disconnect from the exterior elements. InSoFast goes beyond just “CI” or continuous insulation. The fastener that attaches the panel to the substrate is recessed into a ½” into the insulation reducing the fastener’s thermal shorts to near zero. Fastening the exterior cladding does not penetrate the weather resistant or thermal barrier keeping your building secure and dry.
