Cali Bamboo. In development for more than five years, the company is introducing Lumboo bamboo dimensional lumber. Made entirely from compressed bamboo, the material is designed to replace traditional lumber and provide structural strength, density, sustainability, and termite resistance while remaining a cost-effective framing option. Lumboo’s density requires pre-drilling and the use of screws instead of nails when used for building. The engineered bamboo lumber is available in 2x4, 4x4, 2x6, and 1x4 dimensions. 888.788.2254.
