Quality Control & Tolerances.

Standards in the industry

Quality Control

We carefully inspect every piece of glass we work with. Although the U.S. National Standard indicates that imperfections unseen under normal lighting conditions within 11 feet are acceptable, AGI works very hard to exceed these standards. There are times that small inclusions, light scratches, glass seeds and air bubbles will appear in the float glass manufacturing process which can be acceptable within the U.S. National Standard. However, we do our best to eliminate imperfect glass and prevent manufacturing flaws.
