Does the Batt-Bracket system support 24¼-inch wide steel-stud mineral wool batt insulation?

InSoFast Batt-Brackets directly support 24¼-inch wide steel-stud mineral wool batt insulation when installed at 24 inches on-center, providing continuous exterior insulation and built-in rainscreen ventilation for walls and roofs.

Standard wood-stud insulation batts measure 15 or 23 inches wide, which can leave thermal gaps when installed in continuous exterior framing systems. Steel-stud batts are manufactured at 16¼ inches and 24¼ inches wide to maintain a friction fit without compressing the insulation core or creating thermal bypasses across framing members.

If you only do one thing: Install Batt-Brackets at 24 inches on-center to create the exact friction-fit pocket required for 24¼-inch steel-stud mineral wool batts.

• Bracket spacing and sizing: Setting brackets at 24 inches on-center accommodates 24¼-inch steel-stud mineral wool, fiberglass, or wood fiber batts, holding the material firmly in place without mechanical fasteners piercing the batt core.
• Available bracket depths: The system comes in 3.5-inch (yielding R-13 to R-15), 5.5-inch (yielding R-19 to R-24), and 7.25-inch depths to match common batt thicknesses across residential and commercial assemblies.
• Box coverage and pricing: Published online pricing starts at $122.21 per box ($0.89 per square foot), with one box covering approximately 116 to 136 square feet at 24-inch on-center spacing or 77 to 97 square feet at 16-inch spacing.
• Thermal bridge elimination: The bracket design creates an unbroken thermal break across exterior wall framing, preventing conductive heat loss through fasteners and structural members.
• Integrated rainscreen ventilation: The outer bracket flange offsets cladding materials to form a continuous ventilated drainage space that allows trapped moisture behind exterior siding to dry out.

• Watch out for: Installing standard 23-inch wood-stud batts instead of 24¼-inch steel-stud batts at 24-inch spacing, which leaves loose pockets and allows convective air movement behind cladding.
• Watch out for: Specifying Batt-Brackets for below-grade applications; use InSoFast interlocking EPS panels or X-Brackets with closed-cell spray foam for basement walls and below-grade concrete.
• Watch out for: Mismatching bracket depth to batt thickness, because compressing high-density mineral wool into undersized brackets reduces overall thermal R-value and distorts siding planes.

Calculate your exterior wall square footage, divide by 125 to estimate box counts at 24-inch spacing, and select your bracket depth based on your target assembly R-value.
