Mineral fiber compositions with increased levels of SiO2 and reduced levels of Al2O3 and Fe2O3 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≥40.
