Glasswool products are manufactured with quartz sand, feldspar, sodium silicate and boric acid as main ingredients. The ingredients are melted under high temperature and made into fibers thinner than 6μm which are then made into products of different shapes and sizes through shaping under high temperature.
Glasswool Boards are board materials made from superfine rockwool felt with addition of phenol resin cementing agent forming shapes through solidification under pressure and heating. The surface may be coated with PVC film or aluminum foil. These products are characterized by their light weight, high deadening coefficient, remarkable fire resistance and stable chemical property.
