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
Cellulose insulation advantage to a degree, as electricity generation is less than 50% efficient. Cellulose is made with locally available paper, while mineral insulation factories ship materials and products over greater distances. Cellulose insulation uses borates for fire retardation. Borates are a non-renewable mined product. Cellulose insulation The word cellulose comes from the French word "cellule," for a living cell, and glucose, which is sugar. Building insulation is low-thermal-conductivity material used to reduce building heat loss and gain, and reduce noise transmission. Cellulose insulation is plant fiber used in wall and roof cavities to insulate, draught proof and reduce free noise. Cellulose
