Description
Bring the warmth of natural wood to your home with the Northwoods Onyx Ribbed Clear LP Left Side Mosaic garage door. Its multi-tone, digitally printed woodgrain pattern and horizontal plank design create realistic depth, texture, and dimension, while the steel construction keeps maintenance simple. The dark Onyx finish emphasizes the horizontal plank lines for a bold, architectural look with strong contemporary contrast.
This configuration uses Clear Long Panel windows in an asymmetrical left-side Mosaic layout. The wider panes bring natural light into the garage and reinforce the door’s long, horizontal proportions.

Northwoods models explained
Amarr offers Northwoods in two insulated triple-layer constructions. Both use exterior steel, polystyrene insulation, and an interior steel backing, but the door thickness, thermal performance, steel gauges, and warranty coverage differ.
- Northwoods NW3138 – 1-3/8-inch triple-layer door, R-value 6.48 and U-factor 0.27: The slimmer option uses 27-gauge exterior and interior steel. Amarr lists a 12-year paint-finish warranty and a 3-year workmanship and hardware warranty.
- Northwoods NW3000 – 2-inch triple-layer door, R-value 9.05 and U-factor 0.26: The thicker, more energy-efficient option uses heavier 24-gauge exterior steel with a 27-gauge interior steel backing. Amarr lists a 12-year paint-finish warranty and a lifetime workmanship and hardware warranty.
This product defaults to NW3138, and NW3000 can be selected as an upgrade. Choose NW3138 when a slimmer insulated door and lower initial cost are the priority. Choose NW3000 when you prefer greater door thickness, better thermal resistance, heavier exterior steel, and longer workmanship and hardware warranty coverage.
Published R-values describe resistance to heat flow through the solid door section. Overall installed performance can also be affected by windows, seals, door size, installation quality, and site conditions.
