Which is the best insulated garage door?

The best insulated garage doors are the Clopay Canyon Ridge with Intellicore (R-20), the Raynor Innovations Centura (R-18), the Wayne Dalton 9800 (R-17.5), and the Amarr Classica with polyurethane (R-19). All four use polyurethane foam injected between three layers of steel, the highest-performing residential garage door insulation construction available. For top R-value alone, the Raynor Innovations leads. For the best balance of style, insulation, and price, the Clopay Gallery Intellicore at R-18 is the most popular pick. For the carriage-house look with strong insulation, the Amarr Classica is the value winner. Pair any of these with dual-flap bottom seals, thermal weather stripping at the side jambs, and a tight header seal to maximize real-world energy performance.
