Garage doors can take up the bulk of your home's facade and be a big part of the curb appeal. Before you buy, learn about the options, cost and how well they are insulated.

Thankfully, many manufacturers are aware of option overload, and their websites are equipped with digital visualization tools that help you sort through possibilities with a click of the mouse.
Back to the basics
Manufacturers have their proprietary techniques and methods for putting together garage doors, but the basics are these:
• Single-layer construction features a simple outer layer of steel, fiberglass, or engineered wood. The basic doors are lightweight, which is easy on springs, and low cost. Their insulating value is negligible.
• Double-layer construction has an inner and outer skin sandwiched around a layer of polystyrene board for rigidity, and an insulating value between R-4 and R-7.
• Premium construction has inner and outer layers of high-quality steel, wood or fiberglass sandwiched around a thick layer of polystyrene or polyurethane insulation for maximum stiffness and insulating values that exceed R-15.
