Step-by-Step Duct Board Fabrication Instructions

1. Planning and Measurement

Before starting fabrication, create detailed drawings or plans for the duct system, including all dimensions, bends, and fittings. Accurate measurements are critical for a snug fit, optimal airflow, and minimal leaks.

Key points:

• Measure space constraints.
• Determine sizes for straight runs, elbows, transitions, and fittings.
• Add allowances for overlaps, joints, and insulation.

2. Cutting the Duct Board

Using your measurements, transfer markings onto the duct board surface with a pencil or marker.

Cutting tips:

• Use a utility knife with a sharp blade for clean cuts.
• For longer cuts, employ a straightedge or metal ruler to guide your blade.
• Cut slowly and steadily to avoid jagged edges.
• For curved sections, use flexible templates or cut with multiple small cuts for smooth curves.

3. Forming Duct Sections

Once cut, shape the pieces into the required configurations:

• Straight runs: Simply fold or shape as needed.
• Elbows and bends: Use pre-formed elbows or create custom bends by scoring and folding.
• Transitions and fittings: Cut matching pieces to fit into larger sections.

Tip: For corners and bends, score the duct board along the bend line with the utility knife to facilitate smooth folding.

4. Joining Sections

Connect the fabricated sections using the appropriate fasteners:

• Overlap joints: Overlap edges by 1-2 inches.
• Fastening: Secure with stainless steel screws or rivets at regular intervals (every 6-8 inches).
• Adhesives: Apply manufacturer-approved adhesives to seal overlaps, especially in concealed joints.

5. Sealing and Insulation

Proper sealing is essential for system efficiency:

• Seal all joints and seams with UL 181-rated mastic or foil tape.
• Insulate exposed duct surfaces if required, adhering insulation materials as per CertainTeed guidelines.
