Foil backed fiberglass insulation is a premium, high-efficiency thermal and acoustic insulation solution engineered for global industrial, commercial, and residential applications. Combining high-grade centrifugal glass wool with a durable reinforced aluminum foil facing, this advanced multi-layer material delivers exceptional dual-action performance, simultaneously suppressing conductive heat transfer and reflecting up to 97% of radiant heat. Designed to meet strict international standards, it is the ultimate choice for enhancing energy efficiency, controlling moisture, and ensuring long-term structural integrity.
Welcome to the official product page for the high-efficiency foil backed fiberglass insulation, proudly manufactured by China IKING GROUP. Engineered to meet rigorous international building and industrial standards, our foil-faced insulation combines superior thermal resistance with an integrated radiant barrier. This advanced multi-layer design simultaneously blocks conductive, convective, and radiant heat transfer, making it the ultimate choice for commercial, industrial, and residential insulation applications worldwide.



Material Composition: High-grade centrifugal glass wool bonded with a thermosetting resin, faced with a durable reinforced aluminum foil (FSK or WMP facing).
Thermal Conductivity: Low k-value 0.041 ensuring optimal energy retention and reduced operating loads.
Fire Performance: Non-combustible base material meeting strict international fire safety ratings (Class A fire retardant).
Standard Dimensions: Available in customizable roll widths, lengths, and thicknesses (customized densities ranging from 10kg/m³ to 48kg/m³ to suit your project specifications).
Moisture Protection: The integrated foil backing acts as an effective vapor barrier, preventing condensation, mold growth, and moisture ingress in wall cavities and metal buildings.
Traditional insulation only slows down conductive heat flow. Our foil backed fiberglass insulation adds a powerful radiant barrier layer that reflects up to 97% of radiant heat. This dual-action mechanism drastically lowers building energy consumption, helping developers and contractors achieve green building certifications (such as LEED) and long-term utility savings.
In metal buildings, warehouses, and air distribution systems, moisture condensation can compromise structural integrity and indoor air quality. The reinforced aluminum foil facing acts as an impermeable vapor retarder, protecting the underlying fiberglass matrix and extending the lifespan of the entire building envelope.
Beyond thermal insulation, the resilient open-cell structure of our glass wool absorbs sound waves efficiently. It significantly reduces airborne noise transmission in industrial plants, steel structure workshops, commercial auditoriums, and partition walls.
Our foil backed fiberglass insulation is widely specified across global construction and industrial sectors, including:
Pre-Engineered Metal Buildings (PEMB) & Steel Warehouses: Installed easily over purlins and roof decks to regulate interior temperatures.
Air Distribution & Duct Systems: Used as thermal and acoustic wrapping for climate control ducts.
Residential & Commercial Wall Linings: Applied in exterior cavity walls and attic spaces for year-round climate comfort.
Industrial Pipe & Equipment Insulation: Providing robust thermal management for large-scale industrial projects.
