Easy to grow and process, hemp has a number of uses in building, including:
Particleboard based on hemp mixed with other fibers such as flax is lighter, stronger and more moisture resistant than its conventional counterpart. The material in standard chipboard is often held together with formaldehyde-based glues that off-gas over the life of the product. As these glues can’t be used with hemp-based particleboard, it also means a safer product as formaldehyde is a suspected carcinogen.
While it’s not widely available as yet and is more expensive compared to standard chipboard, expect that to change as more companies start manufacturing the product.
