2. Cut – Use a utility knife or fine-tooth saw for precise cuts.

3. Install – Insert the insulation snugly into the recess—no glue or fasteners required.

4. Check Fit – Ensure all panels are secure and the garage door operates smoothly.

Important Note on Garage Door Springs & Motors

• Adding insulation increases door weight, which may require adjustments to torsion springs or motor settings.

• If your motor stops mid-operation, it may need recalibration.

• Never adjust torsion springs yourself—always contact a local garage door professional for safety. This is a very easy and inexpensive job for a professional.
