Saint - Gobain Isover UK, which has a production site situated in Runcorn, utilizes a variety of fusion and fiberizing techniques to convert natural and abundant raw materials (Sand, Borax, and Feldspar etc.) as well as Cullet into a homogeneous melt, which is subsequently fabricated into glass wool fibres. These glass wool fibres are formed into a “mineral wool mat” consisting of a soft, airy structure The best natural insulator on earth is dry immobile air at 10°C: its thermal conductivity factor, expressed in λ, is 0.025 W/(m.K) (watts per meter Kelvin degree). The thermal conductivity of glass mineral wool is close to immobile air as its λ (Lambda) varies from 0.032 W/(m.K) for the most efficient to 0.044 W/(m.K) for the least. The glass mineral wool products have an entangled, porous structure: This enables air to become trapped in the pores of the material providing exceptional thermal properties. Furthermore, its porous and elastic structure absorbs noise in the air and offers acoustic correction inside premises. Incombustible by nature, Isover glass mineral wool does not fuel fire or propagate flames. Glass mineral wool insulation usage is extensive, ranging from use in building insulation (loft, cavity walls) to technical insulation (Industrial facilities, Marine & offshore). It ensures a high level of comfort, lowers energy costs, minimizes carbon dioxide (CO2) emissions, prevents heat loss through pitched roofs, walls, floors, pipes and boilers, reduces noise pollution and protects homes and industrial facilities from the risk of fire. Moreover, Isover insulation allows substantial weight savings for marine applications. The glass mineral wool products generated at Saint - Gobain Isover UK have an average building lifespan of 60 years, or as long as the insulated building component is part of the building. Technical Information Insulation can serve many purposes within a building, from providing thermal and acoustic insulation to fire protection. Saint -
