QUICK ANSWER
The Wayne Dalton Classic Steel 8300 is a three-layer steel door with a foamed-in polyurethane core. It is one of the best-insulated steel doors you can put on a garage.
About the Wayne Dalton Classic Steel 8300
The foam fills every gap between the two steel skins, so the door feels solid, closes quietly, and holds the temperature better than a thin single-layer door. That matters if you use the garage as a gym, a workshop, or a laundry room.
At Royalty Garage Door Repair, we measure your opening, help you choose the panel, color, and windows, and install the door with new tracks, springs, and rollers sized to its weight.
