R-value (insulation) typical straw bale houses have very thick walls and thus are well insulated. Snow is roughly R-1 per inch. Brick has a very poor insulating ability at a mere R-0.2 per inch; however it does have a relatively good thermal mass. Note that the above examples all use the U.S. (non-SI) definition for R-value. When determining the overall thermal resistance of a building assembly such as a wall or roof, the insulating effect of the surface air film is added to the thermal resistance of the other materials. In practice the above surface values are used for floors, ceilings, and
Ministry of Construction of Heavy Industry 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 to the Red
