Building insulation materials is used depends on a wide variety of factors. Some insulation materials have health risks, some so significant the materials are no longer allowed to be used but remain in use in some older buildings such as asbestos fibers and urea. Factors affecting the type and amount of insulation to use in a building include: Considerations regarding building and climate: Often a combination of materials is used to achieve an optimum solution and there are products which combine different types of insulation into a single form. Spray foam is a type of insulation that is sprayed in place through a
IEEE Dielectrics & Electrical Insulation Society recognized conferences that focus on its Field of Interest. 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
