The project specifies characteristic values relating to thermal insulation which shall be applied to technical verification of thermal performance of buildings and building commponents unsing calculation. Design values of thermal conductivity indicated in this prestandard, in particular take into account the influence of temperature, actual moisture content and changing product properties. The water vapour resistance factors indicated in this document are also standard values. The specified values of water vapour resistance factors are intended for assessment of dew protection.
