Electrical insulating glass fabrics are designed for the manufacturing of electrical insulation materials and foil dielectrics, which are used in production of turbo and hydro generators, high voltage electric machines, traction motors, low voltage electric motors and transformers.

Glass filament yarn is a strand of continuous filaments glued together with an sizing agent. Glass twisted yarn is made of non-alkaline aluminum borosilicate glass of E grade, using silane and paraffin sizing agents.

Heat and sound insulating glass fiber blankets are produced from soft wastes of glass fiber production of different chemical composition and with various sizing agents.
