For most Westchester homes, the answer is yes. Here's how to think about it.
When Insulation Matters Most
- Attached garage with living space above (the worst-case for heat loss)
- Garage used as a workshop, gym, or finished space
- Garage with HVAC or radiant heat (don't insulate the walls and skip the door)
- Homes in colder Westchester towns (Yorktown, Bedford, North Salem, Somers, Mt. Kisco)
When You Can Skip It
- Fully detached garage with no plumbing
- Storage-only garage that you don't heat
R-Values Explained
- R-6: Entry-level. Marginal benefit.
- R-13: Solid mid-tier. Right for most attached garages.
- R-18: Best value for garages under living space.
- R-32+: Specialty. Only worth it if your garage is fully heated/cooled.
The Other Benefits
- Quieter — insulated panels dampen vibration
- Stronger — sandwich construction resists dents
- Longer opener life — less weight + less expansion/contraction
Cost vs. Savings
Upgrading from non-insulated to R-13 insulated runs about $400–$700 more on a typical double door. In Westchester's heating season, that pays back in 3–6 years on utility savings alone — plus you get the quieter, stronger door for free.
