Abstract
Mineral fiber compositions with increased levels of SiO.sub.2 and reduced levels of Al.sub.2 O.sub.3 and Fe.sub.2 O.sub.3 compositions are suitable for insulation. The compositions have high temperature resistance and high biosolubility, yet have properties which allow current processes to fabricate them into insulation. The mineral fibers also meet proposed German regulations regarding K1.gtoreq.40.
