Premium Douglas Fir Timbers

J.Gibson McIlvain is Your Source for Fir Timbers & Rough Lumber

Douglas Fir has become a “go to” species in various fields of construction because of its extreme stability and durability in both interior and exterior applications. Douglas Fir is famous for its ability to handle the harshest environments, and its attractive surface takes finishes with exceptional ease. Douglas Fir is a dependable softwood species that has become the industry standard for timber framing.

Inquire about Our Extensive Fir Timber Inventory

Douglas Fir Timbers are a specialty of the J. Gibson McIlvain Company, and you can find an extensive inventory of these timbers at our lumberyards in Maryland and Connecticut. Fir timbers have a superior strength-to-weight ratio which allows them to support massive loads in building construction. Yet their attractive, rustic appearance also makes them a popular choice for custom pergolas, trellis work and other exterior structures.
