Windows-projectile resistant

How many dots should one see with the laser on a projectile resistant window (no label)?

not sure I did see it in a manual once. It does not matter for wind mits as that will not be enough proof for anything. Best guess is 4 but I am not sure. I am sure John or Dennis would know.

“When a laser pointer is pointed at laminated glass, it will show four circles or four ovals as the light passes through. If the glass is tempered or just standard anneal glass, it’ll only show two circles.”[0].pdf

Woo hoo I do have a memory :slight_smile:
