Abstract
The article discusses thermal insulation materials of a fibrous structure based on plant agricultural waste. The results of full-scale tests of flax noils insulation used for thermal insulation of an external wall fence with a ventilated insulation system of a one-story residential building are presented. Data from studies of the thermophysical characteristics of a wall enclosing structure with experimental materials are presented. Temperature distribution graphs along the thick-ness of the wall enclosure structure were constructed, after which the values of thermal resistance to heat transfer were calculated. The dependences of the distribution of humidity along the thickness of thermal insulation were revealed. Based on the results of full-scale tests, it was revealed that at an outside air temperature of -23 °C, the value of thermal resistance to heat transfer of a wall with experimental insulation of flax noils is equal to 3,24 (m2·°C)/W. The research results prove the effective operation of thermal insulation materials based on flax noils for wall enclosing structures.
