Preventing waste and preserving every tree’s story

Most wood loses its history the moment it’s milled, but Carbon Smart Wood preserves it. As the flagship product from Cambium, we track every board from standing tree to final build.

Black Walnut

America's most prized hardwood, rich in color and character.

Cherry

A timeless furniture hardwood whose color deepens with age.

Douglas Fir

A strong, historic softwood with natural character and structural reliability.

English Walnut

A rare orchard walnut with rich, varied color.

Poplar

A clean, versatile hardwood for interior detail and millwork.

Silky Cedar

One of the most sustainably sourced cedars in North America.

Soft Maple

A dense, fine-grained hardwood with a smooth, even character.

Thermal Oak

Exceptional strength and decay resistance for demanding exterior applications.

Thermal Poplar

A lightweight hardwood, thermally modified into a rich, exterior-ready material.

Thermal Sycamore

A thermally modified hardwood with distinctive grain and lasting durability.

WalNOT

The rich, warm tones of walnut in a thermally modified hardwood.

White Oak

Timeless strength and grain, from flooring to fine furniture.

Wood Worth Saving

These trees weren't planted for lumber. They grew in backyards and along streets, came down in storms, fell to disease, or reached the end of their lives, and the wood was headed for waste. We turn it into something you can build with.

Made From Salvage

Salvaged and under-utilized trees that came down through disease, decay, death, or development. Wood that would otherwise be chipped, burned, or landfilled.

Domestically Sourced

American trees, milled in American facilities. Not harvested abroad, and not shipped overseas for processing.

Traceable from Source

Every board is tracked from where it started to where it ships, with the documentation to back it up for certifications and compliance.

Built to Perform

Dimensionally stable, decay resistant, and built to last outdoors or in, whether the durability comes from thermal modification or a naturally durable species.

Chemical Free

Nothing added, ever. The wood is either modified with heat and steam alone or naturally durable by species, so there is nothing to leach or off-gas.

Rich, Real Wood

Genuine grain, depth, and warmth, with color that runs through the board. A material with character, not a manufactured imitation of it.

Frequently asked

What is Carbon Smart Wood?

Carbon Smart Wood™ is Cambium's own line of sustainable wood, salvaged from American trees and either thermally modified or naturally durable by species. It performs across interior and exterior applications, from decking and cladding to flooring, trim, and sauna, and every board is traceable from source to delivery.

Where does the wood come from?

It is salvaged and under-utilized American wood: trees taken down in urban removals, lost to storms and disease, or left over from the fresh-cut lumber stream. These are trees that would otherwise be chipped, burned, or landfilled. We prioritize salvaged and under-utilized material across a domestic supply chain.

What does traceable mean?

Every board is tracked from its source through to delivery. You can see where your material came from and get the documentation you need for certifications and compliance.

How is it made?

Many of Carbon Smart Wood's species are thermally modified in a three-phase kiln process that uses only heat and steam, with no chemicals. The heat restructures the wood's cells, removing the sugars that feed rot and insects and making the wood absorb far less water. The result is a stable, decay-resistant board with a richer tone all the way through. A few species, like cedar, are naturally durable and used without modification.

What can it be used for?

Interior and exterior applications alike: decking, siding and cladding, flooring, trim, sauna, and furniture. It can stand in for tropical hardwoods, chemically treated lumber, and composites. One caveat: thermally modified wood is not intended for structural use, so standard framing should still carry load-bearing elements.

Does it require maintenance?

No finish is required. Left unfinished, the wood weathers to a natural silver-gray patina and is built to last for decades. If holding the original color matters, a penetrating UV oil (CUTEK® Extreme is recommended) can be applied and reapplied as needed; color longevity depends on species, exposure, and surface prep.

What species are available?

The lineup spans thermally modified hardwoods and softwoods plus naturally durable cedar, including Thermal Oak, Silky Cedar, Thermal Poplar, and Douglas Fir, with more by application. Each species has its own page with grain, tone, and recommended uses.
