Symptoms of severe hypocalcemia include numbness or tingling around the mouth or in the feet and hands, as well as in muscle spasms in the face, feet, and hands. Hypocalcemia can also result in depression, memory loss, or hallucinations. Severe hypocalcemia occurs when serum free calcium is under 3 mg/dL.
HeatBloc is an aluminum colored, water-based, low emissivity (low-e) coating. When applied to building materials such as plywood, OSB or plasterboard, HeatBloc lowers their surface emissivity to 0.25 or lower, thereby blocking over 75% of the radiant heat trying to enter the home. It is classified by ASTM as an Interior Radiation Control Coating (IRCC).
The dummy block is a critical element of the aluminum extrusion press. It is a component on which both quality and productivity depend. It has evolved from a simple yet effective basic tool, to a high-tech device that incorporates the results of extensive research and development to perfect its function.
