This door is a three-layer insulated garage door with cascade, long panel windows. This door doesn’t normally come with long panel windows, but we special ordered it to fulfill the customer’s request. These doors have steel on the outside and interior insulation. This opening is called a dutch opening due to the 45 degree corners. We also installed LiftMaster 8550w belt drive openers.
