How is our fiberglass produced?

Fiberglass is a lightweight material renowned for being stronger and more durable than many traditional materials. It is composed of extremely fine glass fibers, thinner than a single strand of human hair.

A look at our fiberglass production process

1. Unloading area: Raw materials are delivered to the production plant and transported through pipes to on-site storage silos.
    
2. Glass batch: The raw materials are mixed to create a powdery glass batch.
    
3. Melting: The glass batch is transferred to a furnace and heated to over 1500°C, where it melts into homogeneous liquid glass.
    
4. Fiberizing – Forming: The molten glass is then transferred via channels from the furnace to a forming area, where it flows directly into fiber-forming bushings.
    
5. Sizing: In this stage, the individual filaments are coated and protected for further textile processing.
    
6. Winding: The fiberglass filaments are wound onto cardboard tubes to form "cakes."
    
7. Cake manipulation: The cakes undergo an automated process that removes all moisture, ensuring they are completely dry.
    
8. Final Processing: This stage is divided into four processes:

• Twisting: A twisting machine unwinds the glass fiber filaments from the cakes, twists them, and winds them onto a plastic bobbin. The twisted filaments, known as twisted bobbin yarn, are then steamed to improve fixation and prevent sloughing.
• Volumizing & Texturing: In volumizing, air is continuously injected into the yarn to increase its volume. Texturing involves injecting air at intervals to create texture. The yarn is then wound onto a paper tube.
• Undirect Chopping: This process cuts dry or wet cakes or bobbins into chopped strands.
• Beaming: Parallel ends of a single yarn from a bobbin are combined and wound onto a beam or warp beam.

Fiberglass: The Core of Our Products

Fiberglass is known for its exceptional strength and durability, ensuring the reliability of our products. Its natural moisture resistance makes it inherently resistant to mold. Fiberglass is integral to nearly every product we produce, including wall coverings, mesh, tapes, and more.
