Style begins with craftsmanship. That's why each American Rivers door is crafted using only the finest woods and materials—from the inside out. To learn more about the door construction, place your mouse over the numbers found within the graphic below.

1. Solid Douglas Fir Frame. Providing unsurpassed strength and structural integrity, doors are framed using high-density, non-finger jointed, 1-3/8" thick (35mm) Douglas Fir.

2. Cedar Trim Boards. Trim boards are constructed from 5-1/4" x 5/8" Western Red Cedar. With natural tannin oils acting as preservatives to resist decay and insects, cedar offers both durability and beauty.

3. Exterior-grade Plywood. The door's interior is backed with 1/4" exterior-grade plywood. No footballs or patches are allowed, resulting in a smooth finished appearance that readily accepts stain or paint.

4. Polystyrene insulation. American Rivers doors are insulated with 1-3/8" thick CFC-free expanded polystyrene, providing an R-value of 7.70.

5. Cedar or MDO Surface Material. Choose from Western Red Cedar surface material in 4" v-groove or bead-board millwork options. Western Red Cedar's rich grain texture and warm tonal range offers an outstanding surface for either stain or paint. Also available is flush medium density overlay (MDO). This smooth surface provides an excellent primed area for painted doors.

6. Integrated Drip Cap. A specially-crafted drip cap in the bottom section channels water away from the face of the door.

7. Cope & Stick joinery. Cope & stick joinery provides increased strength and stability.

8. Cedar Filler Strip. The cedar filler strip protects the door's surface material endgrain from direct moisture exposure.
