Is the Amarr Olympus an insulated garage door, and what is its R-value?

The Amarr Olympus Collection was built around one idea: maximum thermal performance in a residential steel door. Where many insulated steel doors top out around R-9, the Olympus starts at R-14.46 and goes up to R-19.40, depending on which model you choose. That performance gap matters in Colorado, where attached garages share walls with kitchens, bedrooms, and finished living space that bleed heat every winter night.

How Polyurethane Insulation Works in the Olympus

Polyurethane foam-in-place is the reason the Olympus reaches its high R-values. Most mid-range insulated doors use polystyrene (EPS) board: a pre-cut rigid foam panel slid into the door cavity between two steel skins. Polyurethane is different. Liquid foam is injected into the sealed panel cavity and expands under pressure. It fills every corner, including around internal ribs and channels, and bonds directly to both the outer and inner steel faces.

That bond is the key. A polystyrene board insert can shift slightly over years of cycling. Injected polyurethane stays put. The result is a panel with no voids, full adhesion to both steel faces, and consistent thermal resistance throughout its life. R-value measures how well a material resists heat flow per inch of thickness. A higher R-value means the material slows heat transfer more. The Olympus OL3138 reaches R-14.46 and the OL3200 reaches R-19.40. For reference, a typical exterior wall in a well-built home reaches R-13 to R-21 depending on framing.

The polyurethane also acts as a structural brace. The foam bond between both skins stiffens the panel against flex under wind load. Olympus doors operate more quietly than thinner-insulated doors because the foam dampens vibration.

Both Olympus models use 27/27-gauge steel on the outer and inner skins. The three-layer assembly (steel, foam, steel) is standard across the OL3138 and OL3200. The difference between the two models is the depth of the foam fill and the warranty that backs it.

OL3138 vs. OL3200: Which R-Value Do You Need?

The Olympus comes in two models. Choosing between them is straightforward once you know how your garage is used.

Feature	OL3138	OL3200
R-value	14.46	19.40
Insulation type	Polyurethane (foam-in-place)	Polyurethane (foam-in-place)
Steel gauge (outer/inner)	27/27 ga	27/27 ga
Construction	3-layer	3-layer
Paint warranty	Lifetime	Lifetime
Workmanship warranty	5 Years	Lifetime

The OL3138 at R-14.46 is the right pick for most attached garages in the Denver metro. It delivers roughly 60 percent more insulation than a standard R-9 polystyrene door. That difference shows up in winter heating costs and in how comfortable the room next to the garage stays in January.

The OL3200 at R-19.40 is worth the step up in two situations. First, homes at higher elevation: communities like Evergreen, Conifer, and Genesee sit above 7,000 feet, where the heating season is longer and overnight lows are colder than metro Denver. Second, garages used as workshops, gyms, or home offices, where you are trying to make the space comfortable to occupy rather than just limiting heat loss through a shared wall. The OL3200's lifetime workmanship warranty is also a meaningful long-term commitment.

Why Insulation Level Matters in Colorado

Colorado's climate puts garage doors through real stress. Front Range winters produce overnight lows in the single digits from December through February. Summer sun on a south-facing door can push surface temperatures above 140 degrees Fahrenheit. That 150-degree swing happens in the same door, in the same year.

An uninsulated garage door acts like a large thermal hole in the building envelope. For an attached garage, that hole connects directly to the living space. The Department of Energy notes that attached garages with uninsulated or poorly insulated doors can significantly lower the temperature of adjacent rooms during cold weather, driving up heating costs and reducing comfort.

The polyurethane fill in the Olympus handles that temperature cycling better than polystyrene over a long service life. Polystyrene compresses slightly under repeated thermal stress. Polyurethane bonded to both steel faces resists that compression. After 10 or 15 years of Colorado winters, the Olympus holds its thermal rating more consistently than a loose-fill door.

Colorado also averages about 300 sunny days per year. UV intensity at Denver's altitude is roughly 25 percent higher than at sea level. The Olympus's lifetime paint warranty covers fading and peeling over the full ownership period.

Styles and Design Options in the Olympus Collection

The Olympus uses traditional panel designs. Panel formats include Short Panel, Long Panel, Flush Panel, and Long Recessed. The Short Panel is the most common residential format. The Flush Panel suits contemporary or modern-traditional homes. Long Recessed adds horizontal proportion that reads well on ranch-style homes.

Colors available in the Olympus: True White, Almond, Wicker Tan, Sandtone, Dark Brown, Black, and woodgrain finishes in Walnut and Mahogany. The woodgrain options are factory-applied and need no sealing. If a specific color outside this list is needed, confirm availability with G Brothers before ordering.

Window options use the DecraTrim insert system and Mosaic window placement, which allows glass in positions beyond a single fixed top row. Glass choices include Clear, Obscure, Frost, and Dark tint. Insulated glass units are available for homeowners who want maximum performance through every part of the door assembly.

What to Expect from a G Brothers Olympus Installation

G Brothers serves the Denver metro and Front Range, from the northern suburbs through Douglas County and into the foothills. A free estimate covers the opening measurement, existing hardware review, and a side-by-side comparison of the OL3138 and OL3200 so the model decision is clear before you commit.

One important point: a heavier three-layer polyurethane door weighs more than a standard polystyrene or single-skin door. The spring system must be sized for that weight. G Brothers checks spring requirements at the estimate and replaces springs when the existing hardware is not matched to the door's weight. This step is standard and included in the installation scope.

Opener compatibility is a related question that comes up often. A heavier door requires more torque from the opener. If you are keeping an existing opener with a new Olympus door, G Brothers checks the opener's horsepower rating against the door's weight at the estimate. Many homeowners discover they need an opener upgrade at the same time as the door. That conversation happens before any order is placed.

Colorado's freeze-thaw cycles also affect the bottom seal and weatherstripping on any garage door. The Olympus's polyurethane fill keeps the panel more dimensionally stable through those cycles than a polystyrene board insert. The steel skins bonded to the foam do not flex and warp the way hollow-core panels can under repeated temperature stress. That stability helps the weatherstripping maintain consistent contact with the floor and the door frame across seasons.

Homes in Boulder County, Jefferson County, and Douglas County frequently see the combination of hail, cold, and intense UV that makes a premium-insulated door a long-term value. The Olympus's polyurethane construction addresses all three. The foam-in-place bond does not degrade from UV behind the steel skin. The steel skins handle hail. The foam fill handles cold. Over 20 to 30 years of ownership, those benefits compound.

After the install, G Brothers stays available for adjustments, spring replacements, and warranty support. Same-day service is available on most repairs. Free estimates, licensed and insured, 24/7 emergency response across the Denver metro.
