Are 7.25-inch Batt-Brackets compatible with high-density wood fiber batts?

InSoFast 7.25-inch Batt-Brackets are fully compatible with high-density wood fiber batts, engineered specifically to support steel-stud-width batt insulation across exterior wall and roof assemblies without creating thermal bridging pathways.

Builders across the United States and Canada adopting continuous insulation—insulation that runs continuously across structural members without thermal breaks—face fastener sagging and thermal bridging when mounting thick, vapor-permeable materials. As building energy codes push exterior wall assemblies to higher thermal performance requirements, specifiers need non-conductive bracket systems capable of supporting dense 7.25-inch fibrous materials.

If you only do one thing: Specify steel-stud-width batts measuring 16¼ inches or 24¼ inches wide to maintain a secure friction fit against the 7.25-inch brackets.

• Material compatibility: The 7.25-inch Batt-Bracket accommodates dense wood fiber, stone wool, and fiberglass friction-fit batts engineered for deep framing cavities and exterior envelopes.
• Dimensional sizing: Brackets are laid out at 16 inches or 24 inches on center (O.C.), requiring steel-stud-width batts cut to 16¼-inch or 24¼-inch widths to eliminate vertical air gaps.
• Coverage rates: A single box provides continuous coverage for 77 to 97 square feet at 16-inch O.C. spacing, or 116 to 136 square feet at 24-inch O.C. spacing.
• Thermal break isolation: The composite bracket design separates exterior cladding attachments from the structural substrate, stopping conductive heat loss through the building envelope.
• Built-in ventilation: The bracket architecture integrates cross-ventilation drainage planes behind exterior siding, allowing vapor-open wood fiber assemblies to dry out effectively.

• Watch out for: Using standard wood-stud-width batts (15¼ inches or 23¼ inches wide), which leave an open 1-inch channel alongside each bracket and cause convective heat loss.
• Watch out for: Compressing high-density wood fiber batts around attachment plates, which reduces the effective R-value and distorts the exterior rainscreen plane.
• Watch out for: Applying Batt-Bracket assemblies on damp below-grade interior masonry where rigid closed-cell continuous panels are specified instead.

Calculate total exterior wall square footage at your planned 16-inch or 24-inch bracket spacing, then order sample brackets to confirm friction fit with your chosen wood fiber manufacturer.
