A fiberizable glass composition which has a KI value >/=40, while possessing acceptable processing properties such as viscosity and liquidus temperatures is provided. The glass composition processes well in the furnace with acceptably low levels of foaming and is readily fiberizable. The glass has a high boron content, a high soda content, and contains only small amounts of alumina. Further, the glass contains small amounts of barium sulfate which improves the durability of the glass fibers in use.
