Garage Door System GuideAmarr builds steel garage doors with a range of insulation and construction choices. The Classica line offers a carriage-house design in several layer configurations. Buyers select insulation type and layer count to reach the R-value they want.
Construction Options
Amarr offers the Classica door in multiple construction levels. The manufacturer states the line is available in single-, double-, triple-layer construction. Higher layer counts add insulation and rigidity to the steel door.
The layer choice lets buyers match the door to their climate and budget. A triple-layer build sandwiches insulation between two steel skins.
Insulation and R-Value
Amarr insulates the Classica line with a choice of foam types. The manufacturer states there is optional polystyrene or polyurethane insulation. The insulation type affects both thermal performance and door weight.
The insulated R-value spans a broad range. Amarr states insulated door R-values range from 6.64 to 13.35. The top of that range comes from the thicker polyurethane build.
