Glass wool rolls are high-performance, cost-effective fibrous insulation materials widely used in residential, commercial, and industrial construction. Made of high-purity glass fibers via high-temperature melting and centrifugal spinning, these flexible rolls offer reliable thermal insulation, sound absorption, and fire resistance. Lightweight, easy to cut and install, they are a popular insulation choice for energy-saving and durable building projects worldwide.
Core Product Specifications
Our glass wool rolls support standard and fully customizable specifications to fit various project needs. The common density ranges from 25kg/m³ to 48kg/m³ for balanced flexibility and stability. Standard size covers 1.2m width, 10–20m length, and 25mm–100mm thickness. With a low thermal conductivity of 0.038–0.042 W/(m·K), it delivers consistent insulation performance under working temperatures from -50℃ to 250℃. We provide flexible color customization: standard white and yellow, plus custom red and coffee colors for site marking and decorative uniformity. Optional aluminum foil facing boosts moisture resistance and heat reflection. All products meet Class A non-combustible standards with non-toxic emissions, complying with environmental and safety regulations.
Core Product Advantages
Glass wool rolls feature excellent energy-saving effects. Their porous fiber structure effectively blocks heat transfer, cutting building and equipment heat loss by 25%–35% and lowering long-term energy expenses. The fluffy fiber structure also absorbs airborne noise and reduces sound transmission, providing outstanding acoustic insulation. Chemically inert, the material is anti-corrosion, odorless, mold-proof, and pest-resistant for a long service life. Extremely lightweight and flexible, the rolls can be cut to fit irregular spaces, with strong tear resistance to prevent sagging after installation. They are easy to store and transport, greatly saving construction time and labor costs.
Wide Range of Applications
Thanks to its versatile performance, glass wool rolls suit diverse insulation scenarios. In construction, they are ideal for wall, roof, attic, and floor insulation in houses, offices, and commercial buildings. Industrially, they are widely applied in steel structure workshops, factory buildings, and mechanical equipment for heat preservation and noise reduction. They also work perfectly for HVAC duct insulation, cold storage temperature maintenance, and indoor acoustic improvement.
