Description

Fiber Glass Wool is a high-performance, lightweight insulating material composed of fine, interwoven glass fibers. It is engineered to provide superior thermal and acoustic insulation, fire resistance, and dimensional stability across a wide temperature range. This versatile material is essential for industries requiring energy efficiency, noise reduction, and passive fire protection in construction, industrial equipment, and HVAC systems.

Application

• Building & Construction Insulation: Used in walls, roofs, attics, and suspended ceilings for thermal regulation and soundproofing in residential and commercial buildings.
• Industrial Process & Equipment Insulation: Applied to pipes, boilers, furnaces, and storage tanks in power plants, refineries, and manufacturing facilities to conserve energy and protect personnel.
• HVAC & Air Handling Systems: Serves as duct liner and wrap to minimize heat loss/gain and reduce noise transmission in ventilation and air conditioning systems.
• Automotive & Transportation: Used for thermal and acoustic management in vehicle engine compartments, exhaust systems, and cabin interiors.
• Appliance Insulation: Incorporated into ovens, water heaters, and other domestic appliances to improve energy efficiency and safety.
• Fire Protection Systems: Acts as a firestop material in walls, floors, and penetration seals to prevent the spread of flames and smoke.

Quality Control

Our Fiber Glass Wool is manufactured under strict quality management systems to ensure consistent performance and safety. Key parameters such as fiber diameter, density, thermal conductivity, and fire resistance are rigorously tested against international standards like ASTM, ISO, and EN. Certificates of Analysis (COA) and compliance documentation (e.g., REACH, CE marking where applicable) are available upon request to support your procurement and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated warehouse away from moisture and direct sunlight. Keep packages sealed and on pallets to prevent compression and damage to the fibrous structure. Maintain ambient temperature conditions (15-25°C).
