Intended to specify calculation methods which are required for the determination of the quantities to be calculated in DIN 4108 Part 2 and Part 3. The symbols and units necessary for the calculation are summarized in DIN 4108 Part 1, and the heat insulation engineering calculation values and moisture protection engineering standard values are summarized in DIN 4108 Part 4.
