Borosilicate single piece fire-resistant glass cannot be used in the heat insulation or heatproofing radiation function situation which is explicitly demanded cannot be used. 2. Borosilicate single piece fire-resistant glass is processed by specific technology. It cannot be cut, drilled, polished, after it was formed by special process. We will provide our detailed Toughened Parameters to our customers, if you need doing some other process on the glass by yourselves. Besides, please tell us your accurate size and shape requirements about the glass before ordering. 3. Avoid to be scratched on the surface of the glass during transit and installation.
