TimberHP
Wood-fiber insulation manufactured in Maine.
What they're known for
A domestic insulation platform covering cavity batts, dense-pack fill, and continuous exterior boards for vapor-open high-performance assemblies.
TimberHP manufactures wood-fiber insulation in Maine using residual softwood fiber from the regional forest-products industry. The system spans three common enclosure layers: TimberBatt for cavities, TimberFill for dense-pack and loose-fill applications, and TimberBoard for continuous exterior insulation. The importance is not novelty alone; it is a US-made material system that lets designers use one vapor-open insulation family across multiple parts of the envelope.
