Total square-foot wall coverage obtained from one box of Batt-Brackets installed at 16 inches on-center

One box of InSoFast Batt-Brackets yields approximately 77 to 97 square feet of continuous wall insulation coverage when installed at 16 inches horizontal on-center spacing with 48-inch vertical bracket spacing.

Contractors installing continuous exterior insulation often struggle with thermal bridging through metal Z-girts and high material costs for rigid mineral wool boards. Using brackets designed for friction-fit batts provides an engineered exterior continuous thermal break while simplifying material handling on residential and commercial framing jobs across North America.

If you only do one thing: Base your material takeoff on 77 square feet per box for complex architectural elevations with numerous penetrations, and 97 square feet for uninterrupted, simple exterior runs.

• Coverage specifications: At a 16-inch horizontal on-center spacing with standard 48-inch vertical bracket spacing, one box covers between 77 and 97 square feet of wall area.
• Batt compatibility: Brackets accommodate standard steel-stud-width insulation batts measuring 16¼ inches wide, fitting friction-fit mineral wool, fiberglass, or wood fiber.
• Available bracket depths: Available in 3.5-inch (R-13 to R-15), 5.5-inch (R-19 to R-24), and 7.25-inch (R-25 to R-30) depths to meet continuous insulation targets across various climate zones.
• Thermal break performance: The bracket assembly eliminates thermal bridging through structural framing members by holding continuous batts against the weather-resistive barrier without metal through-fasteners.
• Furring attachment: Non-compression mounting plates on bracket faces provide flat, aligned attachment points for vertical furring strips, supporting exterior cladding without wall shimming.
• Labor efficiency: Field installations average 200 to 300 square feet per man-hour, reducing total framing crew installation time compared to traditional clip and rail systems.

• Watch out for: Using standard 15-inch wood-stud batts instead of 16¼-inch steel-stud-width batts, which leaves perimeter voids and compromises the continuous thermal layer.
• Watch out for: Complex wall layouts with multiple window and door openings, which increase bracket density at framing transitions and pull net box coverage toward the low end of 77 square feet.
• Watch out for: Exceeding the 48-inch vertical bracket spacing, which risks batt sag and reduces structural support for exterior siding attachments.

Calculate gross wall area minus large openings, divide by 77 to account for framing transitions, and contact InSoFast at (888) 501-7899 or order a sample pack online to verify spacing for your specific exterior cladding.
