Note: Building code requires that each glass pane must display a tempering stamp.  The stamps vary according to manufacturer - examples.  You may request glass without the tempering logo, but will have to sign a waiver that Phirst & Lassing™ cannot be held responsible for a failed building inspection for certificate of occupancy or for transfer of property at a future date.
