SELECTION CRITERIA OF THERMO-INSULATING MATERIALS TO INSULATE WOODEN BUILDING FACILITIES

The article presents the structure of wood as a fibrous composite made up of cells susceptible to moisture absorption. Attention was paid to the impact of insulation materials on the durability of wood. The flow of moisture in materials such as wood and glass wool representing a group of porous and non-absorbing materials is shown. Microscopic pictures of pine and oak wood, wood fibre mats and glass wool are shown. The full construction of fibers of glass wool and other e. g. mineral wool, makes them extremely non-beneficial for warming partitions in buildings involving wood. Materials with a stable heat conductivity in terms of natural humidity changes in construction works were recommended.
