Great decks begin with great materials. Discover our selection of natural, modified, and specialty wood decking, featuring beauty, strength, and longevity.
Each of our decking materials are selected for its durability, weather resistance, and the kind of lasting appearance you can count on.
Issaquah Lumber specializes in custom-milled profiles tailored for your project needs. We also offer standard profiles for decking sizes and boards that are compatible with the GRAD System. All are available in random lengths with standard widths and thicknesses.
We also offer factory-prefinished options, or you can choose from stain, paint, oiled, brushed, and charred finishes.
Accoya® is a premium, sustainable wood decking available at Issaquah Lumber. Made from FSC®-certified timber and modified for exceptional durability, Accoya resists warping, rot, insects, and splintering—even in the toughest climates. Choose natural Accoya, which silvers beautifully over time, or Accoya Color Grey, with rich color all the way through.
Arbor Wood applies its three-phase thermal modification process to domestically sourced North American species, producing a deck board that performs where it counts — underfoot, in the elements, and over the long term. Heat and steam treatment, with no chemical inputs, eliminates the moisture cycling that causes conventional wood decking to cup, check, and move. The result is a stable, lightweight deck board with a rich, through-color tone and proven resistance to rot, mold, and fungal decay.
Available in Ash and Southern Yellow Pine, Arbor Wood decking offers options for both a finer-grained, contemporary aesthetic and the bold character of a classic domestic species — both elevated by the durability of thermal modification.
LDCwood brings Belgian manufacturing precision to thermally modified decking — sourcing Scandinavian softwoods and enhancing them through a 100% chemical-free heat-and-steam process. The result is a deck board with markedly improved dimensional stability, low moisture absorption, and long-term resistance to rot and decay, without the use of preservatives or chemical treatments.
Its stable performance makes it well-suited to residential decks, commercial outdoor spaces, and high-specification architectural applications. Available in Nordic Spruce and Nordic Pine.
Abodo Imbue decking is sourced from FSC®-certified, rapidly renewable Radiata Pine grown in New Zealand’s plantation forests and modified using a patented thermal process — no chemicals, no Red List substances. Manufactured with a vertical-grain orientation through a patented glue-lamination process, Imbue decking delivers superior weathering characteristics, reduced surface cracking, and exceptional underfoot stability, even in demanding outdoor environments.
Imbue does not require pre-drilling, making it easy to install for both professionals and experienced DIYers. A range of finishes is easily applied and weathers gracefully over time. For outdoor spaces where long-term beauty and environmental responsibility are both part of the brief, Imbue is a proven choice.
Issaquah Lumber’s Legacy Wood decking brings together the enduring appeal of naturally durable softwoods, including Western Red Cedar in both Clear and Tight Knot grades. Clear WRC offers a clean, knot-free surface ideal for refined, design-forward projects where grain consistency and a polished finish are priorities. Tight Knot WRC delivers the same natural warmth and weather resistance in a grade that embraces the character of tight, sound knots — well-suited to rustic, coastal, and Pacific Northwest-inspired aesthetics.
