What causes stuck doors in garage doors?

There are several common causes for stuck garage doors. Broken springs are the most frequent culprit—torsion springs typically last 10,000-15,000 cycles and can snap suddenly. Track misalignment or debris in the tracks can prevent smooth operation. Broken cables, which work with the springs, can cause the door to become stuck or hang unevenly. Faulty garage door openers, including worn gears, burned-out motors, or electrical issues, are also common. Roller damage where worn or broken rollers cause grinding or sticking is another issue.

Insulated Garage Doors in New Boston, NH: What R-Value Actually Means for Your Home

2026-04-06 7 min read

Most homeowners in New Boston spend a lot of time thinking about wall insulation, attic insulation, and window efficiency. and then completely overlook the largest single opening in their home's envelope. The garage door.

In a town where temperatures regularly vary from 15°F in January to 81°F in July, and where snowfall can stretch from October through May, the thermal performance of your garage door isn't a minor detail. It has a real impact on your heating bill and the comfort of your home.

What R-Value Actually Means

R-value measures a material's resistance to heat transfer. The higher the number, the better the insulation. On a garage door, this translates directly to how much cold air bleeds into your garage during a New Boston winter. and how much of your home's heat leaks out through that wall.

Garage doors typically range from R-0 (no insulation at all. just a single layer of steel) up to around R-18 or R-20 for high-end polyurethane-injected doors. That's a significant range, and in New Hampshire's climate, that difference shows up on your utility bills.

A well-insulated door in the R-16 to R-18 range can keep a garage space roughly 10 to 14 degrees warmer in winter compared to an uninsulated door. For an attached garage. which describes the majority of Colonial Revival and Cape Cod homes throughout New Boston and the surrounding area. that buffer matters enormously, because your garage shares at least one wall with your heated living space.

The Two Main Insulation Types

When you're shopping for an insulated door, you'll encounter two primary materials:

Polystyrene

Polystyrene is a rigid foam panel fitted between the door's steel layers. It's the more affordable option and delivers a reasonable improvement over no insulation. Polystyrene panels typically achieve R-values in the range of R-6 to R-13. It's a solid middle-ground choice, especially if budget is a primary concern.

Polyurethane

Polyurethane is injected as a liquid foam that expands to fill every gap inside the door panel. This process creates a denser, more consistent insulating layer with fewer air pockets, and it also adds structural rigidity to the door itself. making it more resistant to denting and warping. Polyurethane doors typically reach R-values of R-18 and above. They're quieter to operate and hold up better over time. For homeowners in colder climates. and New Boston winters qualify. polyurethane is generally the better long-term investment.

If you're also weighing which door style fits your home, our style matching guide is a good companion read. The good news is that most insulated doors come in the same traditional looks. raised-panel, carriage house, flush. that complement the Colonial Revival and Cape Cod styles common throughout town.

How to Think About R-Value for Your Specific Situation

Not every garage needs the highest R-value available. Here's a practical framework:

Attached garage, rooms above or beside it: This is where insulation matters most. Cold air in an attached garage directly affects the adjacent rooms and the floor above. Aim for at least R-12, and seriously consider R-16 or higher if you have a bedroom or home office sharing that wall.

Attached garage used as a workshop or hobby space: If you spend time out there in January, you'll feel the difference between an R-6 and an R-16 door very quickly. Higher insulation also helps protect tools, paints, and other supplies from temperature extremes.

Detached garage used mainly for vehicle storage: A moderate R-value (R-6 to R-9) is usually sufficient here. The priority shifts to keeping the space from freezing solid rather than maintaining true comfort.

For context, New Boston and nearby Merrimack and Londonderry all fall in the same New Hampshire climate zone. cold enough that homeowners should be looking at R-values in the R-12 to R-16 range at minimum for attached garages.

Don't Forget the Weatherstripping

A door rated at R-18 won't perform anywhere near that number if the weatherstripping along the bottom and sides is cracked, compressed, or missing. Air infiltration around the door frame can undermine even excellent insulation values. Before or alongside any door upgrade, make sure:

- The bottom seal makes full contact with the floor when the door is closed, The side seals aren't cracked or pulling away from the frame, The top seal is intact and compressing properly against the header

If you've already gone through a fall checklist, you may have caught some of these. If not, our fall preparation guide walks through exactly what to inspect before cold weather sets in.

Is It Worth the Upgrade?

Honestly, for most attached garages in New Boston, yes. The price difference between a basic single-layer steel door and a quality insulated door has narrowed considerably, while energy costs have not. An insulated door also adds structural strength, runs quieter, and holds its finish longer. all of which contribute to the overall value of a home.

Frequently Asked Questions

Q: Does an insulated garage door actually lower my heating bill? Yes, particularly for attached garages. Insulated garage doors help limit heat loss during colder months, meaning your heating system doesn't have to work as hard to maintain comfortable temperatures in adjacent rooms. The savings vary depending on your current door, your home's overall insulation, and how often the door is opened, but the improvement is real and measurable.

Q: My garage is detached. Should I still bother with insulation? If you use the space regularly. for a workshop, a vehicle you care about, or storing temperature-sensitive items. a moderate level of insulation (R-6 to R-9) is worth considering. If it's purely for storage with no heating system, a basic door is likely fine. The honest answer depends on how you actually use the space.

Q: Is polyurethane insulation worth the extra cost over polystyrene? For most New Boston homeowners with attached garages, yes. Polyurethane fills gaps more completely, achieves higher R-values, adds rigidity to the door panel, and performs better over time. The upfront cost difference is modest compared to the lifespan of a garage door, which typically runs 15 to 30 years.
