Steel doors come in three types of construction – single, double, and triple layer.
• Single layer doors are composed of one layer of steel.
• Double layer doors have one layer of steel plus a layer of vinyl-coated insulation for increased thermal protection.
• Triple layer garage doors are the most energy-efficient doors available. These doors offer polystyrene or polyurethane insulation
sandwiched in between two layers of steel.
