Garage Door System GuideClopay and Wayne Dalton are two established residential steel door brands. This page lays their published construction details next to each other, using Clopay's own buying guide and DASMA industry records for Wayne Dalton. It does not crown a winner, because the right door depends on your climate, budget, and which model within each line you compare.
How to read this comparison
Brand-level specs are only meaningful when you compare like models. Each brand sells a ladder from single-layer builder doors to premium insulated doors, so a premium door from one brand is not comparable to a builder door from the other. Read R-value carefully too, because manufacturers may publish a calculated door section R-value rather than a tested installed U-factor, and DASMA says those two numbers are not comparable. The Wayne Dalton facts below come from DASMA industry records rather than the manufacturer site, which was not reachable at publication.
What Clopay publishes
Clopay builds its steel doors in one, two, or three-layer construction across the Classic, Modern, Gallery, and Bridgeport lines. Its premium insulation, branded Intellicore, is polyurethane foam injected between the steel layers of the door.
On performance, Clopay lists Intellicore R-values reaching 20.4 on its Canyon Ridge Carriage House 5-layer 2-inch and Canyon Ridge Modern Plank 4-layer 2-inch doors, and protects its steel with baked-on polyester paint finishes.
What Wayne Dalton publishes
Wayne Dalton's product details reach the public through DASMA industry records. DASMA describes the Wayne Dalton 9700 series as an insulated steel door offered in a wood-grain finish across six styles, with and without windows, and available in white, clay, gray, and green with white interiors and color-matched low-profile hinges.
DASMA also records that Wayne Dalton doors incorporate a pinch-resistant design and tamper-resistant hardware, and that the brand pairs its doors with the enclosed TorqueMaster spring system, alongside a Model 9800 fiberglass-clad door.
Where they differ on paper
The clearest difference in available records is what each brand documents publicly. Clopay publishes detailed R-value figures for its insulated lines, reaching 20.4 with injected Intellicore polyurethane, while the Wayne Dalton records surfaced here describe construction, finish, and hardware such as its pinch-resistant design and TorqueMaster spring system rather than a specific R-value.
Both brands offer insulated steel doors, but because the published figures come from different source types, a Clopay R-value and a Wayne Dalton design description cannot be equated directly. Matching specific models and confirming the measurement basis matters more than the brand name.
