Properties of Lightweight Insulating Boards Produced from Triticale Straw Particles

Insulating materials made from straw are becoming increasingly popular in the construction industry. Straw can be used of buildings as uncompressed chips or form compressed panels. This study aimed to determine possibility manufacturing boards particles with densities range 150–400 kg/m3, allowing favorable mechanical properties while simultaneously providing high thermal and acoustic insulation properties. The also analyzed influence degree carpentry density on quality manufactured boards. shows that produced satisfactory already at 200–150 kg/m3. Boards this have a compressive strength 150 kPa, resistance 0.033–0.046 W/(m·K), sound absorption coefficient above 0.31.
