Hormann vs Amarr vs Clopay: which garage door brand is best for your Seattle home?

When Seattle homeowners shop for a new garage door, the choice usually narrows to three names: Hörmann (often searched as Hormann), Amarr and Clopay. All three build solid steel garage doors, and each one sells simple entry doors as well as premium insulated models, so the collection you choose matters as much as the brand. This comparison uses each manufacturer's own published specifications to show which garage door is the strongest, which is the most energy efficient, and which brand fits the way you use your garage in Seattle and King County. Hörmann is the brand we install most often, and this guide explains why, with the real numbers for all three so you can judge for yourself.

Hormann vs Amarr vs Clopay at a glance

Figures come from each manufacturer's published product information as of September 2026 and can change by model and year. We confirm the exact R-value and warranty on your written quote. Manufacturer websites: Hörmann, Amarr and Clopay.

Which garage door is the strongest?

Garage door strength has less to do with the logo on the door and more to do with three things you can check on any quote: the thickness of the steel, the number of layers and the type of insulation inside.

Steel gauge: lower numbers mean thicker steel

Steel thickness is measured in gauge, and a lower number means thicker steel. A 24 gauge garage door is thicker and more dent resistant than a 25 or 27 gauge door. Clopay builds its Classic collection in 24 or 25 gauge steel and uses 24 gauge steel for premium colors on its Gallery line. Amarr lists its Heritage collection in 24 gauge steel.

Layers: single, double and triple layer doors

A single layer door is one steel skin with no insulation. A double layer door adds insulation behind that skin. A triple layer door sandwiches the insulation between two steel skins, which makes each section far more rigid and much harder to dent from inside the garage when bikes, balls or car doors meet it. All three brands offer triple layer construction, but not at the same level. Hörmann builds its Therma Tech 3400 and 3500 doors with steel on both the front and the back, while Clopay's Classic Value Plus is a double layer door and Amarr's Heritage comes in single, double or triple layer, so with those two brands you need to choose the right tier.

Polyurethane vs polystyrene insulation

Polystyrene is a rigid foam board fitted into the door. Polyurethane is injected as a liquid, expands to fill every gap and bonds to the steel skins, so the whole section behaves like one solid panel. Clopay reports that its Intellicore polyurethane doors tested twice as strong as polystyrene insulated doors of the same thickness. Hörmann uses polyurethane on its Clima Elite 5800, and Amarr offers it on collections such as Classica.

Insulation and R-value: which garage door is the most energy efficient?

R-value measures how well a garage door resists heat moving through it, and a higher number means a warmer, quieter garage. Based on the published figures, Hörmann rates the Clima Elite 5800, built in Puyallup, at R-15.7, and its Therma Tech 3500, a two inch triple layer door sold only in the western United States and Canada, at R-10.4. Clopay reaches R-20.4 on its Canyon Ridge five layer doors and R-18.4 on its premium Gallery, Coachman and Classic doors with Intellicore. Amarr rates its Classica collection from R-6.64 to R-13.35, and its polystyrene Hillcrest and Heritage doors between R-6.48 and R-9.05.

Seattle winters are mild but long and damp, and many homes in Bellevue, Sammamish, Kirkland and Renton have a bedroom or bonus room over an attached garage. For those homes a polyurethane door such as the Hörmann Clima Elite 5800, at R-15.7, makes a clear difference in comfort and noise. For other attached garages, a triple layer door like the Hörmann Therma Tech 3500 at R-10.4 suits Seattle's mild climate well, and for a detached garage used only for parking a double layer polystyrene door is usually enough.

Insulation also makes a garage door quieter. Clopay measured its Intellicore doors at 80 decibels compared with 96 decibels for traditional doors, and Amarr says its Quiet Door option reduces steel door noise by up to 38 percent. Pair any insulated door with a belt drive garage door opener for the quietest result.

Style and design: which brand has the best looking garage doors?

Hörmann garage doors: built in Puyallup, Washington

Hörmann bought Puyallup's Northwest Door in 2015 and now builds its West Coast residential doors there. The Puyallup lineup covers every style: Therma Tech 3400 and 3500 for traditional raised panel homes, the Clima Elite 5800 with composite wood overlays and the Infinity Classic 7800 for carriage house designs, and Modern Tech 3550, Luma Classic 7400 and Modern Classic 7500 for contemporary homes. You can browse the full lineup on Hörmann's residential site.

Clopay garage doors: the widest range of styles

Clopay has the broadest design lineup of the three. Coachman and Canyon Ridge create the carriage house look, and Canyon Ridge uses composite overlays molded from real wood boards in Clear Cypress or Mahogany textures, so you get the warmth of wood without the upkeep. Gallery covers classic grooved panel designs with decorative windows.

Amarr garage doors: the most color choices

Amarr stands out for color. Its Color Zone program offers more than 800 factory applied colors, which helps when you want the door to match your trim or siding exactly. Classica covers traditional raised panel designs, and Hillcrest brings the carriage house style.

Garage door warranty comparison

Each manufacturer words its warranty differently, and the terms change from one collection to the next, so always ask for the warranty sheet of the exact model on your quote. As published examples, Hörmann lists its Clima Elite 5800 with a limited lifetime warranty on the door, 5 years on hardware and 3 years on springs. Amarr lists a lifetime warranty on the steel of its Heritage collection. Clopay publishes a separate warranty document for each collection.

Keep in mind that a manufacturer warranty covers defects in the door itself, not the installation. A door that is installed out of balance or with the wrong springs wears out early on any brand, which is why a licensed installer matters as much as the name on the door.

Which garage door brand should you choose?

For most homes we install across Seattle and King County, Hörmann is our first recommendation: a door built in our own region, with solid construction and a warranty that stands behind it. Clopay and Amarr are good brands too, and we install them when a specific style, color or R-value calls for it. If you are still deciding whether your current door is worth fixing, read should I repair or replace my garage door first.

Frequently asked questions

Which garage door brand do you recommend for Seattle homes?

For most homes we recommend Hörmann. Its West Coast garage doors are built in Puyallup, Washington, its Therma Tech doors have steel on both the front and the back, and the polyurethane insulated Clima Elite 5800 is rated R-15.7 with a limited lifetime warranty on the door. It is the brand we install most often.

Which is better, Clopay or Amarr?

Clopay offers more styles and higher insulation, up to R-20.4 with Intellicore polyurethane. Amarr is a strong value brand with more than 800 factory colors and R-values up to 13.35 on Classica. For an attached garage where comfort matters, a polyurethane Clopay door usually comes out ahead. For a well built door in an exact color, Amarr is an excellent choice.

Is Hormann a good garage door brand?

Yes. Hörmann is a family owned German company that has made doors since 1935, and its West Coast garage doors are built in Puyallup, Washington, at the former Northwest Door plant it acquired in 2015. Its Therma Tech doors are triple layer steel with a polystyrene core, and the polyurethane insulated Clima Elite 5800 is rated R-15.7 with a limited lifetime warranty on the door.

What is the strongest type of garage door?

A triple layer steel garage door with a thick 24 gauge skin and an injected polyurethane core. The polyurethane bonds to both steel skins, so each section acts as one rigid panel that resists dents and flexing far better than a single layer or polystyrene door.

What R-value garage door do I need in Seattle?

For a garage with a bedroom or bonus room above it, choose a polyurethane door in the R-12 to R-18 range, such as the Hörmann Clima Elite 5800 at R-15.7. For other attached garages, a triple layer door around R-10, like the Hörmann Therma Tech 3500, works well in Seattle's mild climate. For a detached garage used for parking, a double layer door between R-6 and R-9 is usually enough.

Are Hormann garage doors made in the USA?

Yes. Hörmann builds its North American sectional garage doors in the United States, at factories that include Puyallup, Washington, and Montgomery, Illinois. The Puyallup plant supplies dealers across the western states.

Do you repair Clopay, Amarr and Hormann garage doors?

Yes. We repair and service doors from all three brands, including springs, cables, rollers, panels and openers, and we carry common parts on the truck so most repairs across Seattle and King County are finished in one visit.
