Published starting cost per square foot for the Batt-Bracket continuous insulation system

The published starting cost for the InSoFast Batt-Bracket continuous insulation system is $0.89 per square foot, with complete boxes starting at $122.21 for exterior wall and roof framing assemblies.

Energy codes across the United States and Canada increasingly mandate continuous exterior insulation to eliminate thermal bridging through structural framing members. Builders and specifiers frequently encounter challenges balancing material costs, attachment labor, and exterior sheathing requirements when engineering high-performance wall assemblies.

If you only do one thing: Space brackets at 24 inches on-center with 5.5-inch depths to achieve up to 136 square feet of coverage per box at an effective thermal rating of R-19 to R-24.

• Base pricing: Brackets start at $122.21 per box, which equals a baseline starting material cost of $0.89 per square foot before primary insulation batts.
• Box coverage: Each box covers 77 to 97 square feet at 16-inch on-center stud spacing, or 116 to 136 square feet when installed at 24-inch on-center intervals.
• Bracket depths: Available sizes include 3.5 inches (R-13 to R-15), 5.5 inches (R-19 to R-24), and 7.25 inches to match specified continuous insulation depths.
• Material compatibility: Brackets hold steel-stud-width batts measuring 16.25 inches or 24.25 inches wide, including mineral wool, fiberglass, and dense wood fiber.
• Assembly integration: The built-in bracket profile creates a ventilated rainscreen cavity behind cladding while eliminating thermal bridging across exterior wall framing.

• Watch out for: Standard wood-stud batts sized at 15 inches or 23 inches wide, which will create uninsulated voids because the system requires 16.25-inch or 24.25-inch steel-stud-width batts.
• Watch out for: Below-grade installations on interior basement walls, since Batt-Brackets are designed for exterior walls and roofs rather than interior foundation slabs.
• Watch out for: Under-specifying bracket depth on exterior walls in cold climate zones where local energy codes require thermal values higher than 3.5-inch R-15 profiles deliver.

Calculate the total exterior square footage and framing spacing of the building envelope, then select the bracket depth corresponding to your project's target continuous insulation rating.
