Analysis of Thermal Insulation from Renewable Resources

One of the essential requirements for buildings is energy saving and heat retention. About 40% of the total energy consumed in the European Union is used for heating of buildings. Most of the energy consumed in buildings is used for heating during the cold period and cooling during the warm period. A significant part of energy can be saved due to suitable insulation of buildings. More efficient energy saving can be ensured by using heat-insulating materials produced from renewable resources. In Lithuania straw is often used for making thermal insulation obtained with a thermal conductivity of 0.040 W/(mK). Straw thermal conductivity under different conditions as well as possibilities to use it for producing heat-insulating materials are analysed in the work.
