Retrofitting existing buildings represents an opportunity to upgrade energy performance. Current building insulation materials including Vacuum insulation panels (VIP) are neither safe nor environmentally sustainable and can be cost-prohibitive for retrofits. InventWood’s proprietary wood delignification process creates many nanopores in the mesoporous lignocellulosic structure with greatly enhanced thermal insulation compared to natural wood. This unique structure makes the delignified wood (nanowood) an excellent technology platform that enables wood in many insulation applications that were impossible before. In SBIR Phase I and II, InventWood and team has achieved: (1) achieved a low thermal conductivity of ~30 mW/(m·K); (2) scaled up the manufacturing to a size of 8in'36in'0.5in (W'L'T); (3) identified first commercial market (insulating wall planks) for a first-generation nanowood product and established business relationships with potential partners; and (4) received first commercial revenues for delignified reed evaporators developed based on the delignified wood technology.
