R-8 to R-18 insulation retrofit for existing steel doors. Reduces transferred heat by up to 71%, lowers AC load on attached garages, and noticeably quietens door travel.
We handle garage door insulation across San Castle year-round. The local reality — year-round heat and humidity, frequent tropical downpours, and salt-tinged moisture that never lets metal fully dry — guides which springs, rollers, and seals we install.
The environment around San Castle is unforgiving on hardware. Year-round heat and humidity, frequent tropical downpours, and salt-tinged moisture that never lets metal fully dry means constant humidity that swells wood doors and rusts steel hardware, year-round salt-marine air that corrodes springs, cables, and fasteners, and storm-season wind that stresses panels and bottom seals, so we build every quote around durability.
There's a familiar rhythm to San Castle breakdowns — rusted track hardware and seized rollers near the water, degraded weatherstripping from constant UV and salt, moisture-tripped openers and sensors, and salt-pitted spring coils that fail early near the coast. We've fixed each a thousand times across Palm Beach County.
Garage door insulation is one of the cheapest energy upgrades available to most homeowners with attached garages. Uninsulated steel doors radiate heat into the garage all afternoon — and into the adjacent rooms whose walls share with the garage. Adding R-8 to R-18 insulation cuts measured heat transfer by up to 71%, drops attached-garage temperatures by 10–15°F on hot days, and noticeably reduces the AC load on rooms that share walls with the garage.
We do retrofit insulation on existing steel doors using EPS foam panels cut to fit each section, with reflective vinyl facing and a perimeter seal. The retrofit takes 2–3 hours per door, can be done in place without removing panels, and works on most thin-skinned and double-skinned steel doors. Wood doors and full-view doors aren't candidates for retrofit insulation — we'll tell you upfront if your door doesn't suit the upgrade.
Beyond energy, insulation makes the door significantly quieter. The foam dampens panel resonance, which is the main source of bass-y rumble during operation. Homeowners often comment that the noise reduction alone justified the project. For homes with bedrooms above the garage, this is meaningful.

Uninsulated doors on the sunny side of a home easily push attached-garage temperatures to 105–115°F. Insulation drops that 10–15°F.
Room next to garage runs warm
Bedroom or living space that shares a wall with the garage often runs 3–5°F warmer than the rest of the house. Door insulation helps; wall insulation is the bigger fix.
AC bill spikes in summer
Attached garages bleed conditioned air through the door if there's a return-air path. Insulation slows the heat ingress.
Garage workshop or gym in use
Spending hours in the garage on hot days is uncomfortable without insulation. The upgrade pays back fast for active garage users.
Excessive door noise
Uninsulated panels resonate during travel. Insulation foam dampens the resonance for a noticeable noise reduction.
Common causes & what we fix
Builder-grade non-insulated doors
Tract construction commonly uses the cheapest non-insulated steel doors. They meet building code but ignore comfort and energy efficiency.
Sun-side exposure
South and west-facing garages take the brunt of afternoon sun locally. Insulation is highest-leverage on these exposures.
Habitable space above garage
Bonus rooms and bedrooms over the garage transfer heat from below. Door insulation helps; full ceiling insulation is the bigger lever.
Garage as workshop or gym
If you use the garage for work or workouts, comfort improvements have direct quality-of-life payback.
Older home with no garage insulation
Pre-1990s homes often have no insulation in the garage at all. Door insulation is a logical first step.
