Calcium silicate bonded with sodium silicate. Although it is popularly considered an asbestos substitute, early uses of calcium silicate for insulation still made use of asbestos fibers. It is used in passive fire protection and fireproofing as calcium silicate brick or in roof tiles. It is one of the most successful materials in fireproofing in Europe because of regulations and fire safety guidelines for commercial and residential building codes (see Calcium Silicate use in Europe). Where North Americans use spray fireproofing plasters, Europeans are more likely to use cladding made of calcium silicate. High-performance calcium-silicate boards retain their excellent dimensional stability even
IEEE Dielectrics & Electrical Insulation Society IEEE Dielectrics & Electrical Insulation Society The IEEE Dielectrics and Electrical Insulation Society (DEIS) is a professional society of the IEEE. The Professional Technical Group on Electrical Insulation held their first meeting on September 16, 1963, and changed their name shortly after to the Group on Electrical Insulation in May 1964. In 1978 the group's name was changed to Electrical Insulation Society and in 1986 became the Dielectrics and Electrical Insulation Society. IEEE DEIS produces two major publications that deal with its Field of Interest: Transactions on Dielectrics and Electrical Insulation and Electrical Insulation Magazine. IEEE DEIS sponsors several internationally
