1. Borosilicate single piece fire-resistant glass cannot be used in situation that has clear request for heat insulation or heatproof radiation function.
2. Borosilicate single piece fire-resistant glass is spe- cially processed safety glass. After the shape processing, it cannot be processed.
3. Avoid borosilicate single piece fire-resistant glass surface being scratched when moving and installing it.
