What Builders Say

From production builders to custom contractors, Weyerhaeuser structural wood delivers consistency where it counts.

"

We switched to TJI floor systems three years ago and haven't had a single squeaky floor complaint since. The consistency from bundle to bundle is remarkable — it's made our framing crews 15% faster.

VP of Construction, Stonegate Homes

"

When we spec Edge Gold subfloor, the inspectors know what to expect. The ICC evaluation reports are thorough and every panel is stamped — it makes the permit process straightforward.

Priya Castellano

Project Manager, Meridian Build Group

"

The framing lumber arrives at proper moisture content every time. Warping and twist are minimal, and our framers appreciate the predictability. For high-volume production, that reliability translates directly into savings.

Frequently Asked Questions

Technical and purchasing questions answered by our product specialists.

TJI® engineered I-joists are manufactured under controlled conditions using oriented strand lumber flanges and a structural plywood or OSB web. Compared to sawn lumber, TJI joists offer consistent strength, are significantly lighter per linear foot, and can span longer distances without intermediate support. They resist shrinkage and warping — the main causes of squeaky floors — because their moisture content is controlled during manufacturing.

Recreation permits for access to Weyerhaeuser-managed timberlands are available through regional offices. Requirements vary by state and land parcel. Use our Contact page to reach the appropriate regional team, who will guide you through the permit map and application process. Note that permit rules can change seasonally during active harvesting operations.

Yes. Our engineered wood products — TJI joists, glulam beams, and structural panels — are evaluated by ICC Evaluation Service (ICC-ES) and carry current ESR (Evaluation Service Report) numbers. These reports provide prescriptive installation tables and span data accepted by building departments in all 50 states and most Canadian provinces. Download the relevant ESR from our Products page or request it via our technical support team.

Our framing lumber lines are available with FSC Chain of Custody and SFI certification, and all lumber is graded to NLGA, WCLIB, or WWPA rules under ALSC oversight. For projects requiring specific certifications (LEED credits, state procurement requirements, or export), specify the required certification when requesting a quote and our sales team will match you to the appropriate product line.

Weyerhaeuser products are distributed through a nationwide network of lumber dealers and building material distributors. Use the Request a Quote form to describe your project and location — our team will connect you with the closest authorized dealer who carries the specific products you need. Dealer stock and specialty items like glulam beams may require lead time, so plan ahead for large orders.
