FUNAS Glass Wool Insulation – High Quality Glass Wool Process
Product Overview
FUNAS glass wool insulation is a high-performance thermal and acoustic material made through a controlled glass wool manufacturing process. Since 2011, FUNAS has combined research, production and service to deliver durable insulation solutions for industries like petrochemical, power, metallurgy, polysilicon, central air conditioning and refrigeration. Our Guangzhou hub includes a 10,000 m² storage center to ensure timely supply.
Glass Wool Manufacturing Process
1. Raw Materials
High-quality silica sand, recycled glass and flux materials are selected to ensure a stable melt and consistent fiber quality.
2. Melting & Fiberizing
Materials are melted at high temperature to form molten glass. The molten glass is then fiberized using controlled spinning or flame techniques to create fine, uniform fibers that trap air and provide insulation.
3. Binder Application
A specially formulated binder is applied to the fibers to give the mat structure and resilience. The binder is chosen for low smoke, low odor and long-term stability.
4. Curing & Cutting
The fiber mat passes through curing ovens to set the binder. After curing, the glass wool is cut and shaped into boards, rolls or loose-fill forms according to customer needs.
5. Quality Control & Packaging
Strict inspections check density, thermal conductivity, dimensions and fire performance. Products are then packed to protect against moisture and contamination during transport and storage.
