Fire-retardant mineral insulations

Asbestos is a naturally occurring mineral and was widely used as an insulation material in building constmction [35]. Asbestos possesses a number of good physical characteristics that make it useful as thermal insulation and fire-retardant material. It is electrically nonconductive. [Pg.72]

The sources of asbestos and other mineral fibres in indoor environments are fire-retardants, acoustic, thermal or electric insulation and structural material. Some of the mineral fibres such as asbestos were used commonly in the past... [Pg.136]

These can be inorganic materials such as calcium silicate, mineral wool, diatomaceous earth or perlite and mineral wool. If provided as an assembly they are fitted with steel panels or jackets. These are woven noncombustible or flame retardant materials the provide insulation properties to fire barrier for the blockage of heat transfer. [Pg.169]

The technical suitability of insulation materials is described by a series of technical parameters relating to the material (heat conductivity and heat storage capacities, damp protection, fire protection class, noise-insulating effect, properties related to building biology, e g. content of hazardous substances such as flame retardants and insecticides). Mineral wools have certain advantages over other insu-... [Pg.75]
