Abstract: Thermal bridges are an important issue for buildings built with the use of sustainable materials based on organic components, such as wood and hemp-lime composite. Increased heat losses in construction junctions reduce the temperature of the internal envelope surface, causing moisture condensation and mould growth, especially dangerous in the case of materials susceptible to biological degradation.
Constructions from wood and organic insulating filling are considered sustainable, thanks to the low carbon dioxide emission during the production and building process, possibility of recycling and the opportunity of using locally prepared materials and components. Building partitions presented in the paper consist of a timber frame forming the load bearing structure, filled with a hemp-lime composite acting as the stiffening, thermal insulation and fire protection. Numerical analyses of the window placement in an external wall took into account different thermal conductivity of the composite together with various types of walls and jamb construction. Thermal parameters of hemp-lime composites were obtained from the authors’ own research.
