glass-based insulation

glass-based insulation

Made of glass fibers combined with reinforcing agents. Fiberglass is the most widely used. Recycled glass insulation is a composite made from glass fibers and a polymer. Glass-based insulation systems are used for roofs, attics, walls, ducts, pipes, as well as other home appliances and equipment. Glass-based insulation products have relatively small deterioration rates and high R-values, ranging from R-11 to R-38. They can be blown into any void to any desired R-value. Since the base material is made of sand and recycled glass, it is naturally noncombustible, requiring no additional chemical treatment. Moreover, glass-based insulations are not absorbent and retain their R-value, even after they are exposed to moisture. See also: Insulation systems

Fibre glass-based insulation is not the best material to be handling, with small, flaky particles finding their way inside even the most carefully-worn protective gear.
