Advanced Treated Woods

T2EARTH introduces 'OnWood Plywood' in celebration of Earth Month 2025 as a breakthrough in sustainable, fire-resistant building materials. Engineered without toxic chemicals, OnWood Plywood offers builders a high-performance, eco-conscious solution ideal for use in fire-prone and high-humidity regions.

Certified by the International Code Council (ICC-ESR 4627), this Class A fire-retardant treated wood (FRTW) outperforms traditional chemical-treated alternatives—delivering up to 91% greater strength while resisting termites and mold. Made from sustainably sourced wood and manufactured in the USA, OnWood Plywood comes with a 30-year limited warranty and is available in standard 4'x8' panel sizes for framing, sheathing, and underlayment.

T2EARTH is also launching the 'THINKOnWood' initiative alongside this release -- a community-driven platform to unite architects, builders, and policymakers in promoting fire-hardened, eco-friendly construction as the new national standard.

The launch of OnWood Plywood positions T2EARTH as a leader in climate-resilient construction materials. By offering a non-toxic, code-compliant alternative, the company responds to growing market demand for safe, sustainable housing solutions. Combined with THINKOnWood, this initiative could accelerate regulatory shifts, expand market reach, and catalyze the adoption of resilient building practices across wildfire-prone regions.
