| description | The present invention concerns glass compositions capable of being attenuated in the form of fibers. These glass fibers comprise the following oxides in the percentages by weight: SiO2:37 to 48%; Al2O3:17 to 25%; CaO:23 to 33%; MgO:0.1 to 7%; Fe2O3:0.1 to 3%; Na2O:2 to 8%; K2O:0.1 to 7%, the sum of the percentages of earthalkaline oxides (CaO and MgO) being less than or equal to 34%, and the sum of the alkaline oxides (Na2O and K2O) being greater than 5%. The invention is applicable to the manufacture of products subjected to elevated temperatures, for instance, products used for insulation purposes, even when such products may be subjected to a temperature as high as 700 DEG C. |
