Clear Douglas Fir

Clear Douglas Fir is best known for its tough fibre, dense grain structure and strength. Appreciated by designers and architects alike it has rich visual quality that responds to fine craftmanship and finishing.


Ideal for all types of joinery applications including fascia, doors, millwork, window and door casings, mantels, stairs and baseboards. Although most softwoods are not suitable for flooring, Douglas Fir will hold a finish, remain level, resist scuffing and cracking and maintain its appearance under extreme wear. The higher grades of Clear Douglas Fir as stocked by Illingworth Inghan (M/cr) Ltd, are quite refined with sound, tight knots making it suitable for shelving, cladding and panelling. It is dimensionally stable and recognised for its strength-t0-weight ratio. Its high specific gravity provides superb nail and plate-holding ability.

Clear Douglas Fir machines to an exceptionally smooth, glossy finish and when dry it retains its shape and size without shrinking, swelling, cupping, warping, bowing or twisting and generally won’t show a raised grain. Clear coatings, transparent lacquer, varnishes, oils, wax, bright or subdued stains, tints or paints and enamels are all appropriate finishes.
