Your specs, not ours.

We keep a range of hardwoods in stock kiln-dried, and some already thermally modified. Anything we have kiln-dried, we can thermally modify for you.

Use it for furniture, saunas, doors, trim, cladding accents, tables, planters, interior panelling, almost anything you can build. The only exception is load-bearing work. Our lumber isn’t strength-graded, so it always goes on a rated structural frame.

Give us a call, tell us what you’re building, and we’ll do our best to make it work.

Kiln-dried or cooked.

Option 01

Kiln-dried

Conventionally dried hardwood with its natural colour, ready for interior furniture, cabinetry and millwork.

  • Natural species colour
  • Rough or planed
  • Finish with any standard wood finish
Option 02

Thermally modified

Cooked in our kilns with heat and steam, no chemicals. The wood comes out darker all the way through, more stable, and far more resistant to rot and moisture.

  • Rich, even colour through the board
  • Less swelling, shrinking and cupping
  • Built for saunas, outdoor projects and humid rooms

Mostly ash. Plenty more.

Ash is our workhorse and the bulk of what we process. We also carry the species below, and sometimes others. Stock moves quickly, so reach out to find out what’s in the yard right now.

About cooked stock

We don’t always have every species in stock already thermally modified. If you want yours cooked, it goes in with the next scheduled kiln load, so wait times depend on when that cook is. Reach out and we’ll tell you where the schedule stands.

The standard run.

Most of our lumber comes in the sizes below. We occasionally have other thicknesses, like 6/4 or 12/4, so if your project calls for something specific, ask.

Not for load-bearing use. Dimensional lumber from ThermalWood Canada isn’t strength-graded. Install it on a rated structural frame.
