This invention involves a fiberglass composition containing the following components: SiO2, Al2O3, CaO, MgO, B2O3, F2, TiO2, K2O, Na2O, Fe2O3 and SO3. The weight percentage of each of the components are as follows: SiO2 58˜65%, CaO 20˜26%, Al2O3 9˜17%, MgO 0.5˜1%, B2O3 0˜5%, F2 0˜1%, TiO2 0.1˜1%, K2O+Na2O 0˜0.8%, Fe2O3 0.1˜0.5%, SO3 0˜0.6%. The ternary system, SiO2—Al2O3—CaO, is basis of the fiberglass composition in this invention, which also has low quantities of MgO and B2O3. In addition, the total amount of alkaline earth oxide and the proportional r...
