Many manufacturers use R-values to show the energy efficiency of their product. This number is calculated based on the thickness of the insulation and its chemical properties. Therefore, most of the published R-value numbers reflect only the R-value of a section, not of the installed door. A door's insulating capabilities can be greatly affected by the door's construction. For that reason, Amarr's insulated doors are built to maximize energy efficiency. Our thermal break, door section construction and insulation help keep your garage as comfortable as possible. When comparing R-values, make sure manufacturers' R-value are calculated similarly.
