MeadowBoard™ is a formaldehyde-free rye grass straw panel available in 4’ x 8’ sheets from 1/8″ to 1″ thick. Rye grass straw is an agricultural waste product from grass seed production. This coarse-textured interior finish material can be custom-molded into various shapes. This material is not an M3-rated structural panel product. It is produced in high density veneer or hard board, medium density standard board, and low density “Bulletin or Tackboard”. When compared to many wood composite products MeadowBoard™ panels have physical properties of higher strength to weight ratio, higher dimensional stability, fire resistance, insulation, and acoustical qualities .
