Abstract
Provided herein are projectile resistant glass treatment assemblies. The assemblies provide resistance to penetration of a glass pane by projectiles moving in a direction from the exterior to the interior of the glass pane.
Claims53
A transparent projectile resistant glass assembly, comprising:
- a pane of glass with a thickness of about 0.25 to 1 inch;
- a single-ply film, wherein the single-ply film is adhered to an exterior surface of the glass;
- between one and six layers of a three-ply film laminate, wherein the three-ply film laminate is adhered to an interior surface of the glass;
- and
- whereby the glass assembly has a break strength starting at about 600 psi, a tensile strength of at least 30,000 psi, and an optical clarity of at least about 85%.

A method of preparing a projectile resistant window assembly, comprising:
- applying to an exterior surface of a glass pane having a thickness of 0.25 to 1 inches a single-ply film with a pressure sensitive mounting adhesive;
- applying between three to eighteen layers of a single-ply film comprising the pressure sensitive mounting adhesive to an inside surface of the glass pane;
- wherein the mounting adhesive provides a peel strength in the range of about 6 psi to about 10 psi;
- and
- wherein the window assembly has an optical clarity and a break strength starting at 600 psi and a tensile strength of at least 30,000 psi.

A transparent projectile resistant window assembly, comprising:
- a pane of glass with a thickness of about 0.25 to 1 inch;
- a single-ply film, wherein the single-ply film is adhered to an exterior surface of the glass;
- between three to eighteen layers of single-ply polyethylene terephthalate film adhered to an interior surface of the glass;
- and
- whereby the window assembly provides a break strength starting at about 600 psi, a tensile strength of at least 30,000 psi, and an optical clarity of at least about 85%.
