Glass Wool Insulation Suppliers, Saudi Arabia
Glass Wool Insulation is a fibrous thermal and acoustic insulation material manufactured from molten glass spun into fine fibres, used in building roofs, walls, HVAC ductwork, and industrial pipe insulation across the GCC. It is one of the most cost-effective and widely used insulation materials in the Gulf, available as blankets, rolls, and rigid boards. Regional manufacturers produce glass wool in the UAE to serve the Middle Eastern market.

Glass wool insulation is produced by melting sand and recycled glass at high temperatures and spinning the molten material into fine fibres bonded with thermosetting resin. Products include flexible blanket rolls (for roof and wall cavity insulation), rigid and semi-rigid boards (for external wall insulation and HVAC duct lining), and pipe sections (pre-formed half-shells for mechanical insulation). Thermal conductivity ranges from 0.032 to 0.044 W/mK depending on density and temperature, with densities from 10 kg/m3 for light blankets to 100 kg/m3 for high-density acoustic boards.
In the UAE and Saudi Arabia, glass wool is specified for metal roof and wall insulation in industrial and commercial buildings (blankets laid over purlins), residential wall cavity insulation, HVAC duct external insulation (with aluminium foil facing as vapour barrier), and acoustic insulation within partition walls and ceiling systems. Key specifications include thermal conductivity (lambda value), density, maximum service temperature, fire classification (typically A1 or A2-s1,d0 non-combustible per BS EN 13501-1), and facing type (unfaced, aluminium foil faced, or glass tissue faced).
Major glass wool manufacturers supplying the GCC include Knauf Insulation, Isover (Saint-Gobain), Owens Corning, and Arabian Fiberglass Insulation Company (AFIC — the largest regional producer based in Ras Al Khaimah). Regional production provides cost and lead-time advantages over imported alternatives. Procurement managers should specify glass wool per the thermal design engineer's requirements, ensure that the selected product carries the appropriate fire classification (non-combustible is mandatory for most GCC building applications), and verify that vapour barrier facings are correctly oriented (facing the warm/humid side in air-conditioned Gulf buildings). Lead times from regional stock are typically 1 to 2 weeks.
