As the weather heats up, it’s the perfect time to consider insulating your garage door, especially if you use the space a home gym or workshop. Adding insulation to the door’s interior channels can help keep your garage an average of 20 degrees cooler in the summer. Insulation may also reduce noise transfer, increase energy efficiency, and brighten what might otherwise be considered a dreary space.
This is a relatively easy and affordable DIY project.
Purchase the Right Insulation Material
Rigid Foam Insulation: Typically made from expanded polystyrene (EPS), extruded polystyrene (XPS) or polyisocyanurate (“iso”), rigid foam insulation is an acceptable choice for garage door insulation if they are foil-faced and fire-rated. R-values for rigid foam insulation range from 3.3 to 6.5 per inch of thickness.
Batt Insulation: Commonly composed from fiberglass, batt insulation is more flexible than rigid foam insulation, with insulation values between R-3 and R-4 per inch of thickness. Not as good as rigid foam insulation, but still a viable option, especially considering batt insulation is one of the most affordable options available.
An R-value is the resistance of heat flow through a given thickness of material. The higher the value, the greater the thermal resistance and therefore, the energy savings. An R-value is just one of four key factors you should consider.
These are all factors that should also be taken into consideration when selecting an insulation material. For maximum energy savings, it’s also important to consider insulating the entire garage, and not just the door.
Matching Insulation to Your Garage Door
- Steel garage doors can accommodate any type of insulation
- Wood frame garage doors can accommodate foam board insulation. Consider applying two layers
- Flat garage doors (doors without panels) can accommodate rigid foam insulation
