High Performance Sound Deadening Glass Wool Insulation Cavity Wall





Our complete glass wool production lines employing latest-generation technology to manufacture boards, rolled blankets and pipes for residential and industrial thermal and acoustic insulation needs, in compliance with the top international standards (EN, DIN, ASTM).

At the system HOT END, the raw materials are dosed, mixed, melted, fiberized, impregnated with a special binder and formed into a primitive mat of very fine fiber glass. Continuous conveyors transport the mat to the COLD END of the plant for binder polymerization. The product is then cut to shape and packed for shipping.

Our glass wool production lines range from 5 to 700 tons/day capacity (100,000 to 1,500,000 tons/year), and are fully automated thanks to PLC and Scada systems.

Production lines comply with the latest international environmental regulations.
