Specifies thermal insulation parameters for use in the design of the thermal insulation of buildings and their elements. The guideline values specified for the moisture resistance factor are to be used when making a rough assessment of the protection against condensation as specified in DIN 4108 Part 3. The design values of thermal conductivity, lambdaR, allow for, among other factors, the effects of temperature, the actual moisture content 1) and variations in the material properties.
