ABSTRACT:
Fiberizable glass composition with increased levels of B.sub.2 O.sub.3 and Na.sub.2 O are suitable for insulation. Coupled with alumina levels as high as possible, these glasses have improved durability. Moreover, these glasses have physical properties which allow current processes to fabricate them into insulation. The glasses also meet proposed German regulations regarding Kl.gtoreq.40.
