technical data sheet for panels

InSoFast continuous insulation panels feature two-by-four-foot expanded polystyrene boards with embedded polypropylene studs at sixteen inches on-center, integrated electrical raceways, and continuous insulation ratings ranging from R-8.5 to R-10.5 across standard configurations.

Specifiers and contractors working across the United States, Canada, and Mexico face continuous insulation mandates under International Energy Conservation Code (IECC) guidelines that penalize thermal bridging from standard steel or wood framing. Rigid composite panels resolve framing, vapor regulation, and insulation within a single profile to manage condensation risks against concrete, masonry, framed walls, and container steel.

If you only do one thing: Verify substrate flatness and clean contact surfaces before applying adhesive beads along the back of each embedded stud to ensure full structural attachment.

• Dimensions and coverage: Standard panels measure 24 inches by 48 inches (nominal 2 ft x 4 ft) providing 8 square feet of continuous coverage per unit, featuring tongue-and-groove interlocking edges that self-align across spans.
• Core material specifications: Molded with closed-cell expanded polystyrene (EPS) foam per ASTM C578 standards, providing nominal thermal resistance ratings of R-8.5 at 2.0-inch thickness and R-10.5 at 2.5-inch thickness.
• Embedded stud framing: Internal injection-molded polypropylene studs are spaced 16 inches on-center, providing thermal-break attachment points that accept standard drywall screws and support direct cladding installation.
• Integrated utility chases: Factory-molded electrical raceways run vertically along each stud and horizontally across panels, allowing code-compliant installation of non-metallic sheathed cable without trenching the foam.
• Moisture and drainage design: Engineered capillary channels molded into the back face direct incidental moisture and condensation down to perimeter drainage systems, maintaining a semi-permeable vapor profile that permits wall drying.

• Watch out for: Using solvent-based adhesives or expanding canned foams that dissolve expanded polystyrene; specify only approved modified polymer or polyurethane construction adhesives.
• Watch out for: Overdriving drywall screws through the polypropylene studs, which strips the fastener engagement and reduces holding power for wallboard or exterior siding.
• Watch out for: Leaving installed panels exposed in habitable interiors without the code-mandated 15-minute thermal barrier, such as 1/2-inch gypsum drywall, per standard fire safety regulations.

Review project wall assemblies against regional energy code continuous insulation targets, then calculate total gross square footage with an additional 10 percent allowance for cutoffs and openings.
