Garage Door Insulation Checklist

Preparation

• Inspect garage door for cracks, dents, or damage.
• Gather tools: tape measure, utility knife, adhesive/tape, weatherstripping, caulk.
• Choose insulation material:
• Foam board panels (high efficiency)
• Fiberglass batts (noise reduction)
• Reflective panels (hot climates)
• Spray foam (professional use)

Step 1: Measure & Cut

• Measure each garage door panel.
• Cut insulation to fit snugly inside panel cavities.

Step 2: Install Insulation

• Place insulation inside each panel.
• Secure with adhesive, tape, or clips.
• For fiberglass, cover with plastic/vinyl sheeting.

Step 3: Seal Gaps

• Apply weatherstripping around door edges.
• Seal joints with caulk or foam sealant.

Step 4: Test & Adjust

• Open and close door to ensure insulation doesn’t interfere.
• Trim excess material if needed.

Pro Tips

• Use insulation with higher R-value for better efficiency.
• Check garage door opener capacity (added weight).
• Prevent moisture buildup by sealing properly.
• Consider replacing with a pre-insulated garage door for long-term solution.
