Clear Douglas Fir


Appreciated by designers and architects alike Douglas Fir has a rich visual quality that responds to fine craftsmanship and finishing.

It is best known for its tough fibre, dense grain structure and strength.

Attractive Grain and Colour

Mainly sourced from Canada but also the USA, Douglas Fir has a light, rose colour, which darkens over time when exposed to UV rays. When sawn, its vertical grain is particularly attractive and has a remarkably straight grain pattern.

Exceptional Finish

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.

The higher grades of Douglas Fir, as stocked by Illingworth Ingham (M/cr) Ltd, are quite refined with sound, tight knots making it suitable for cladding. It is dimensionally stable and recognised for its strength–to-weight ratio. Its high specific gravity provides superb nail and plate-holding ability.


Clear coatings, transparent lacquer, varnishes, oils, wax, bright or subdued stains, tints or paints can all be applied satisfactorily.
