Intectural Joins the International ThermoWood Association

When thermally modified wood specs fail, it’s rarely because of aesthetics. It’s generally because performance claims couldn’t be held to a clear, enforceable standard.

In a market with countless modified wood options, architects, designers, and builders need more than promises, they need accountability.

That’s what Intectural’s recent acceptance into the International ThermoWood Association provides. Membership means ThermoWood specifications are backed by an internationally recognized, audited standard, not just a product name or a manufacturer’s claims.

ThermoWood Certification

ThermoWood certification isn’t a label. It’s a system. Materials are produced, tested, and documented against defined criteria, giving design teams a benchmark that holds up during board reviews, approvals, and value-engineering discussions—when material decisions are most likely to be questioned or changed.

We’ve seen too many projects where ‘thermally modified wood’ sounded right on paper, but there was no standard to fall back on once questions started coming. ThermoWood changes that. It gives teams something objective to point to when decisions are challenged. Jason Peterson VP, Intectural

Intectural is the U.S. distributor of Arbor Wood Co., an ITWA-accredited product with domestic production and on-the-ground support from our team in Duluth, Minnesota. That combination reduces uncertainty from submittal through installation. Specifiers receive consistent documentation. Builders receive boards that match the profiles and tolerances shown in the drawings. Owners receive a material designed to perform as expected.

If you’re preparing a board review or evaluating modified wood options for an upcoming project, request Arbor Wood Co. samples or ThermoWood technical documentation. Our team can help you compare detailing, maintenance, and climate performance—so you can move from intent to installation with confidence.
