Thinking about adding insulation to your garage door? Discover the benefits for energy efficiency, noise reduction, and durability.
If your garage is attached to your house, it’s likely the biggest source of heat loss in your home. A thin, uninsulated metal garage door acts like a giant heat exchanger, letting cold in during winter and heat in during summer.
Benefits of Insulation
- Lower Energy Bills: By keeping the garage temperature more stable, you reduce the load on your HVAC system, especially if you have rooms above the garage.
- Durability: Insulated doors (often “sandwich” construction with steel-foam-steel) are much stronger and less prone to denting than single-layer steel doors.
- Quieter Operation: The foam core dampens vibration, making the door significantly quieter when opening and closing.
- Comfort: If you use your garage as a workshop or gym, insulation makes it usable year-round.
DIY Kits vs. New Door
- DIY Kits: You can buy foam panel kits to glue onto your existing door. They help a little, but they add weight (which might require spring adjustment) and don’t seal as well as a factory door.
- New Insulated Door: The best option. Factory-insulated doors have higher R-values (thermal resistance) and better seals between sections.
R-Value Matters
Look for an R-value of at least R-12 for attached garages in New Jersey. The higher the number, the better the insulation.
