On Earth Day, T2EARTH® Launches OnWood® Plywood — The Highest-Performing Eco-Friendly Fire-Retardant Plywood and A National THINKOnWood™ Fire Protection Initiative

In recognition of Earth Day, T2EARTH® announces the launch of OnWood® Plywood, the most advanced eco-friendly fire-retardant treated wood (FRTW) on the market. Made without toxic chemicals, OnWood® delivers unmatched strength, Class A fire retardancy, and sustainable design—offering builders and developers a healthier, higher-performing, affordable alternative for fire-prone environments. Combined with OnWood® Dimensional Lumber, T2EARTH® meets the demands of a new era of eco-friendly fire-retardant “hardened homes.”

Developed for fire-resilient, code-compliant materials, OnWood® Plywood is independently certified by the International Code Council (ICC-ESR 4627) and exceeds performance standards for both structural integrity and fire safety.

• From 19% to 91% stronger than traditional toxic chemical treated FRTW plywood
• Class A Fire Retardant — ASTM E84 & E2768, Flame Spread 10 / Smoke Developed 10
• ICC Product Listing Certified for termite and mold resistance barrier protection (ICC-ESL 1640)
• Non-toxic — no formaldehyde, halogens, or harsh chemicals
• Sustainably sourced wood from FSC®, SFI®, or comparably managed forests
• Manufactured in the USA with a 30-year limited warranty

Available now in 4'x8' panels (½", ⅝", ¾"), OnWood® is ideal for framing, sheathing, and underlayment—particularly in high-risk wildland-urban interface (WUI) zones and high humidity regions.

Coinciding with the OnWood® Plywood launch, T2EARTH® is introducing THINKOnWood™, a nationwide communities-based initiative to unite professionals across architecture, real estate development, construction, community leadership and code design/enforcement in promoting eco-friendly Fire Hardened Homes as the new building standard. T2EARTH®’s THINKOnWood™ platform will offer education, policy guidance, building professionals focused collaboration tools, and homeowners’ forums to help accelerate safer, affordable and climate-resilient construction.

“OnWood® represents the future of building materials: fire retardant, strong, safe, affordable and sustainable,” said Joel Kier, Co-Founder and CEO of T2EARTH®. “And with THINKOnWood™, we’re helping lead a national shift in how we build to meet today’s risks and fire-prone community needs.”
