Borosilicate flat glass, often called borofloat, is a clear COE 33 sheet. Full sheets of borofloat are usually 45"x33", available in several thicknesses. The flat glass is sold by weight, each thickness at a different price. When available, the sheet can be cut to the size that you request. A small cutting fee may apply. Please call for more information or if you need the borofloat cut to a specific size.
