Amarr / Garage door / Family guide
Northwoods is a three-layer steel family with a printed horizontal woodgrain design and two documented insulation thicknesses.
Identifier: Northwoods. This guide compares a family or related models. Use the exact configuration on your label.
Models covered: NW3138, NW3000. They are separate configurations; compare the applicable facts and documents below.
NW3138 and NW3000 have separate entries in the official specification index; keep the full code when selecting documents.
The product page directly associates NW3138 with thinner insulation and NW3000 with the 2-inch option. Compare those configurations rather than treating Northwoods as one rating.
The woodgrain appearance is printed on a ribbed section; it should not be identified or maintained as a solid-wood door.
