Garage Doors Construction
One layer garage doors are inexpensive steel doors, It is not insulated or not quiet as 3-layer doors. Single-layer garage doors tend to be the most affordable
Two layer garage doors are a nice option for getting a insulated door. These doors start with a 1-layer door, but have vinyl-backed polystyrene insulation added behind the first outside layer of steel.
Three layers (steel + insulation + steel) garage doors are stronger and durable doors. A triple layer garage door is an insulated model—it can also be referred to as a three layer, or sandwich, door. The insulation is hidden, or sandwiched, between the inner and outer metal pans. The two layers that sandwich the insulation are typically steel but can also be wood or fiberglass.
