The lateral loads that non-load-bearing walls can carry should not be more than 10 pounds per square foot. Metal screws do not contribute to energy-efficient structures due to thermal bridging. The thermal bridge allows heat to flow from inside the building along the most conductive path, the metal screws. ComparedContinue Reading

Track ball valves are popular in larger sizes where generating sets are required, which are cheaper than an operator for a conventional quarter round ball valve. Open and close so quickly that ball valves can cause water hammer or surge pressures. The hollow ball can catch liquid in closed positionContinue Reading
