CAFboard Compressed-Straw Panel Is Back
Using American-made waste straw for wallboard, insulation, and acoustic applications, Stramit USA has brought back CAFboard.
Despite their promise as a durable, rapidly renewable building material that uses agricultural waste, compressed-straw boards have not taken off in the U.S. That’s not for lack of trying: counting various straw composites, EBN has covered the comings and goings of more than a dozen products over the last 20 years. The newest entrant is the second coming of CAFboard from Stramit USA, which previously shut down in 1996 after a year of production. Based in Forth Worth, Texas, the company has been producing Stramit CAFboard (“CAF” stands for compressed agricultural fiber) for the last two years and is shipping across the U.S.
Made from wheat straw, with no added binder
CAFboard is a compressed-fiber panel manufactured from wheat straw. The company markets the boards for SIPs, door cores, interior sheathing, acoustical panels, and many other applications. CAFboard is processed under high heat and pressure, which convert lignin already present in the straw into a natural binder; no formaldehyde or other binder is added, and, according to the company, testing shows zero VOC emissions.
