FSC-Certified Solid Hardwood
Solid wood from sustainably managed forests — no urea-formaldehyde resin, no off-gassing.
Toxicity Screening — All Clear
This material screens clear across all seven independent toxicology authorities we use on every project.
Material Type
Solid Wood (Certified Sustainable)
Material Description
Solid hardwood is unmodified wood — cut from the log, dried, milled, and finished. The Forest Stewardship Council (FSC) certification ensures the wood came from a forest managed for long-term ecological health, with chain-of-custody documentation linking the finished board back to its specific harvest tract. The critical detail for indoor air quality is what solid hardwood does NOT contain: no urea-formaldehyde binder (the way engineered wood, plywood, and MDF use), no phenol-formaldehyde, no isocyanate adhesive. Once a clear oil or water-based finish is applied and cured, the only off-gas signature is residual wood-volatile terpenes — the smell of fresh wood — which are present at low ppb and are not regulatory concerns.
Composition & Origin
Health Profile — All Endpoints Clear
Severity scored 0–10 against the same 10 hazard endpoints we use for the chemical families on the avoid list. Every score is 1–2 — essentially no signal across every endpoint.
Common Forms & Brands
- FSC-certified oak, maple, walnut, cherry, ash, hickory
- Domestic species (white oak, hard maple, black walnut)
- Common framing: solid plank flooring, dimensional lumber, hardwood paneling, hardwood doors
Why We Use It
- Zero added binders or adhesives — wood is the wood
- FSC chain-of-custody documents responsible forestry
- Carbon-storing — locks CO₂ for the life of the building
- Refinishable — can be sanded and resealed many times
- Repairable and recyclable end-of-life
Where It Performs Best
- Solid plank flooring
- Dimensional framing lumber
