Why Choose CVG Douglas Fir?
Superior Stability: Vertical grain (quarter-sawn) cuts are significantly less prone to warping, twisting, or cupping compared to flat-sawn lumber.
Architectural Beauty: Known for its warm, honey-redvdish tones and remarkably consistent, pinstripe grain pattern.
Clear Grade: This stock is "Clear," meaning it is virtually free of knots, pitch pockets, and defects on all four surfaced sides.
Workability: Despite its strength-to-weight ratio (one of the highest of any softwood), it machines beautifully and holds fasteners securely.
Best For:
Exterior door and window casings
Custom cabinetry and shelving
High-traffic flooring or porch transitions
Modern slatted wall installations
Pro Tip: Douglas Fir is naturally decay-resistant, but for exterior use, we recommend a high-quality UV-inhibiting sealer to maintain that iconic "bright" fir color and prevent silvering.
