Is an Insulated Garage Door Worth It in Central Indiana?
For an attached garage that you use every day, especially one under a bedroom, an insulated door is usually worth it. It keeps the garage warmer in winter and cooler in summer, quiets the door and adds stiffness. For a detached shed-style garage, a basic door may be fine.
Request a technicianHow cold does it get?
Nearby Indianapolis averages a January temperature of about 28°F, with a few nights a year at or below 0°F. Summers are hot and humid, with highs at or above 90°F on about 18 days a year.
What are the main types?
Single-layer steel doors have no insulation. Two-layer doors have steel and a foam backing. Three-layer doors sandwich foam between two steel skins. Polyurethane foam insulates better than polystyrene for the same thickness.
What else does insulation do?
It makes the door quieter and more rigid, so it dents less easily and flexes less in the wind.
Does it matter if the garage walls are not insulated?
You will get less benefit, but the door is usually the biggest single opening, so insulating it still helps.
What about the cost?
Insulated doors cost more than basic doors. A technician can quote both options for your opening so you can compare. See new insulated doors.
Can I insulate my current door?
Kits are available for some single-layer doors, but they add weight, so the springs must be adjusted. A technician can tell you whether your door is suitable.
Does the garage being under a bedroom change things?
Yes. A cold garage below a bedroom makes the floor above it cold, and a hot garage in July does the opposite. An insulated door, along with weatherstripping around the door and an insulated wall between the garage and the house, is one of the most effective ways to make that room more comfortable. It is often the first upgrade worth looking at when a bonus room over the garage feels uncomfortable.
