Because borates absorb infrared radiation, their incorporation into building products such as glass wool, and other insulation products help prevent heat loss through infrared transmission.
Cellulose insulation is used mainly as loose-fill for insulating lofts, attics or cavity walls, though spray-on varieties are available for application to ceilings or side walls by means of an adhesive. Because cellulose insulation is primarily made of wood, cotton, and other plant-derived raw materials, it is inherently flammable and prone to smoldering combustion. The use of borates in cellulose materials imparts flame retardancy, enabling them to meet stringent safety standards and regulations. U.S. Borax Optibor® boric acid has long been recognized as an effective flame retardant additive due to its capability of preventing smoldering combustion. The combination of Optibor and Neobor® yields reliable fire and corrosion performance. Borates are soluble in water and can be sprayed as aqueous solution on the shredded paper during the manufacturing process. The high solubility and high boron content of Polybor® often make it a preferable choice for wet application.
