6VAC15-81-970. Security glazing.

c. Glazing in interior partitions inside the secure perimeter shall be Security Grade 4 or better.

4. Security glazing panels shall be no larger than 36 inches by 48 inches unless located a minimum of seven feet above floor level.
5. Glazing security grade may be reduced one level if lowest portion of glazing is 12 feet above adjacent floor level.
6. Tempered or insulated glass or both may be used in openings five inches or less in one direction unless bullet resistant or contraband resistance is required, in which case glazing rated for such shall be used.
7. Glass security glazing or glass clad security glazing shall not be used unless required for fire rating or unless approved by the reviewing authority on a case by case basis for specific locations.
8. Plate glass, float glass, and other conventional glass other than wire or tempered glass shall not be used in any openings located within the secure perimeter or in any interior security walls, interior partitions, doors, or other openings within the area enclosed by the secure perimeter. Wire glass may only be used where required for fire rating purposes.

12. All openings, such as windows, louvers, clearstories, and skylights, penetrating the secure perimeter walls, floors, or roof shall be protected by bar grille or woven rod partitions constructed as required by subdivisions A 1 c (4) and A 1 c (5) of 6VAC15-81-930 when they are larger than:
a. Eight inches by eight inches; or

Where stops are placed in an inmate area, they shall be secured with an ample number of strong, properly installed, tamper resistant fasteners of design required by 6VAC15-81-930 or approved by the reviewing authority. Junctions of horizontal and vertical glazing stops on the inmate side shall be welded to prevent removal of portions of stop members.
