Douglas Fir Siding

Marks Lumber’s Douglas fir siding options offer both strength and natural beauty to help set the tone for your home.

Douglas fir makes a fantastic exterior wood siding material because it’s sturdy and naturally weather-resistant. It’s the highest-rated North American softwood in strength-to-weight ratio and stiffness, and it’s less susceptible to shrinkage than many other species.

The unique grain patterns and swirls of Douglas fir – matched with Marks’ authentic circle-sawn texture – give it a distinctive look. It works well in traditional and modern homes and cabins alike, bringing an organic, cozy feel to any project.

Explore our variety of Doug fir siding products including circle-sawn shiplap, board and batten, 105, and waney edge – all manufactured here at our sawmill in Montana.
