The price of glass wool roll felt is usually calculated in cubic meters or square meters, and is significantly affected by density, thickness, brand, and additional functions such as fire resistance, hydrophobicity, aluminum foil veneer, etc. The non-ferrous metal industry uses glass wool rolls with specifications of 1.2 meters long, 10mm thick, and 90mm wide. This size combination is quite special (1.2 meters long but 90mm wide). Typically, glass wool rolls are long strip rolls with standard specifications such as 600mm and 1200mm wide, ranging in length from 3-20 meters. Some high-end products or special customized specifications may exceed this range.
