Glass Fiber Formation Process

Once the glass mixture reaches its molten state, it undergoes a fascinating transformation into glass fibers. This process, known as fiberization, involves forcing the molten glass through tiny holes in a rapidly rotating spinner. As the glass exits these holes, it's immediately stretched into extremely fine fibers by high-pressure air streams. These fibers, measuring only a few microns in diameter, cool rapidly and are coated with a binding agent. This binding agent is crucial as it helps the fibers adhere to each other, forming a cohesive insulation material. The resulting glass wool is a network of intertwined fibers that trap air pockets, giving it its excellent insulating properties. This unique structure is what makes glass wool an ideal core material for sandwich panels, offering superior thermal and acoustic insulation.
