Development of Materials Based on Flax for Thermal Insulation andThermal Rehabilitation of Structures

Peer-reviewed article not indexed in WoS or Scopus

Thermal restoration of building constructions presents a complex of measures during renovation and life prolongation of buildings. It is a solution including restoration of bearing parts of the construction, solutions of moisture questions and the thermal insulation and new surface treatments of the construction. After application of the thermal insulation total energy intensity for heating and cooling is reduced and the thermal comfort inside insulated object is improved. Nowadays at application of thermal insulating systems a huge amount of insulants produced from non-renewable materials (EPS, PUR) is needed or the production of these is energy demanding (rock wool). Some of them, namely foam-plastic insulating materials are not compatible with original walling materials and after its application the diffusion flow is frequently limited in direction to exterior. The paper describes possibilities of production of insulants from flax waste and use of such insulating materials in the field of exterior heat insulating materials for existing objects.
