Is an Insulated Garage Door Worth the Extra Cost?
Insulated doors cost 20–35% more than non-insulated. They're worth it for some homes, a waste for others. Here's how to decide.
Definitely Worth It
If you have living space directly above or beside the garage. If you use the garage as a workshop, gym, or office. If your HVAC ducts run through the garage. In all of these, R-12 to R-18 doors pay back in 4–6 years through HVAC savings.
Maybe Worth It
Detached garages used for vehicles only — but you'll appreciate not getting in a 110°F car in July.
Probably Not Worth It
Outbuildings used purely for storage with no shared walls to conditioned space.
What R-Value to Pick
Pittsboro, NC's mild climate makes R-12 (polystyrene) a sweet spot. R-18 polyurethane is worth the extra $200–$400 if you have living space above.
If anyone spends time in or above the garage, insulation pays back fast.
