Light acoustic systems made of lignocellulosic particles of annual plants
Title of the offer
Light acoustic systems made of lignocellulosic particles of annual plants
Offer description
Light symmetric and asymmetric acoustic systems composed of annual plant particles are made of cereal straw (i.e. wheat, rye or triticale straw) and have a relatively low density. This kind of systems are used as thermal and acoustic insulation for walls and ceilings, and may also be laid under floor coverings. The average density of these systems varies in the range of 150 kg/m3 to 280 kg/m3, although asymmetric systems are more dense. Despite their low density, systems made of particles of annual plants have a high compressive strength of over 150 kPa at 10% deformation. The systems can be manufactured as a board with no finishing or as large-size boards which are cut into elements of a size suitable for trading.
