Borosilicate fire resistant glass has smoothly passed the States Fire extinguishing
Systems Test.
Fire-Proof Glass not only has superb fire resisting performance but is extremely hard
for glass. It is 10 to 12 times stronger than ordinary glass of the same thickness,
and 2 to 3 times stronger than tempered glass.
