The new Ambient line of Safe-Way Steel Garage Doors are insulated with a high-density, 2-inch polyurethane foam core, which has an R-value of 17.68 for increased thermal performance. The outer layer of galvanized steel combined with the insulated core creates a durable, sound-resistant, and dent-resistant material, says the company. The doors are available in seven color and two wood-grain options and six panel styles, and they can be customized with a variety of window configurations. Pricing varies. safewaydoor.com
