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
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
