Glass Wool Rolls
Glass wool blanket is a high-performance insulation material made from natural minerals such as quartz sand, limestone, and dolomite. These raw materials are melted at high temperatures and processed into fine fibers using centrifugal technology. The result is a lightweight, flexible, and resilient blanket that is widely used in construction and industrial applications.
1. Appearance & Color Options:
Natural Color: The standard fiber color is typically yellowish-green.
Custom Colors: To meet diverse architectural aesthetics and project requirements, we offer products in Red, White, and Brown(Coffee).
2. Facing Options:
Aluminum Foil: The most common option, providing excellent vapor barrier and thermal efficiency.
Colored Non-woven Fabric: Available in red, white, or brown for a clean, finished look, ideal for interior decoration.
Fiberglass Cloth: White or black options for enhanced mechanical strength and fire resistance.
3. Specifications & Customization
Density: 10-80 kg/m³
Thickness: 25-200 mm
Dimensions: Standard widths of 600mm, 1000mm, 1200mm (custom lengths available)
Core Advantages:
Excellent Thermal Insulation: With a low thermal conductivity of 0.032 - 0.044 W/(m·K), it effectively reduces heat transfer, keeping interiors warm in winter and cool in summer.
Superior Sound Absorption: The porous structure traps sound waves, converting them into minimal heat energy, significantly reducing noise and improving acoustic comfort.
Class A Fire Resistance: As an inorganic, non-combustible material with a melting point of ~650°C, it provides reliable fire protection.
Durable & Eco-friendly: It is corrosion-resistant, mold-proof, and contains no asbestos or CFCs. It is hydrophobic (water-repellent) and designed for a long service life.
Easy Installation: Its flexibility allows it to fit perfectly around pipes, ducts, and irregular structures, making construction fast and efficient.

Applications:
1. Architectural field: used for heat and sound insulation of walls, ceilings, floors, etc., as well as heat preservation of air conditioners and pipes. Compared with traditional insulation materials, glass wool blankets have better heat preservation performance and can effectively reduce energy consumption.
2. Ship field: used for compartments, heat preservation, heat insulation and noise reduction treatment to improve the safety and comfort of ships.
3. Automobile field: used for heat insulation, noise reduction and heat preservation of car bodies and engines, with higher fire resistance and stable heat preservation performance, while reducing the vibration and noise of the car chassis.
4. Home appliance field: used for heat insulation, heat preservation and noise reduction of refrigerators, air conditioners and other products, reducing energy consumption and improving noise isolation effect.
