Thermal conductivity common use in the construction and textile industries. The construction industry makes use of units such as the R-value (resistance) and the U-value (transmittance). Although related to the thermal conductivity of a material used in an insulation product, R- and U-values are dependent on the thickness of the product. Likewise the textile industry has several units including the tog and the clo which express thermal resistance of a material in a way analogous to the R-values used in the construction industry. There are a number of ways to measure thermal conductivity. Each of these is suitable for a limited range
Ministry of Construction of Heavy Industry Gate Square. "Source": Ministry of Construction of Heavy Industry The Ministry of Construction of Heavy Industry of the USSR (Mintyazhstroy; ) was a central government institution charged with leading the heavy industry of the Soviet Union. It was established in 1946 to replace the several successor Commissariats to the People's Commissariat of Heavy Industry of the USSR, dissolved in 1939. After liquidation in 1953, it was reactivated from 1967 to 1986. The ministry headquarters was one of the Seven Sisters built during the last 10 years of Stalin's life, also known as the Red Gate building owing to its proximity
