Why Design for Security Protection?

• Burglary, Forced Entry, Ballistic Attacks, and Bomb Blasts and are more and more common

• A burglary occurs every 11 sec in the US

• Bomb Blast events are globally on the rise

• Flying glass shards: 50+% of all non-fatal blast injuries.

• Flying or Falling Glass #1 cause of injury non-structural collapse

Types of Security Glazing

Standard LAG (1/4” with 0.060” thickness) provides a significant improvement in resistance to attack from a variety of hand held weapons in:

– Residential: Rock, Hammer, Pry bar, Brick, etc.– Commercial: Sledgehammer, Battering Ram, Chisel,

Axe

LAG cannot be cut from one side deeming glass cutters useless

Impact resistance is improved as % of interlayer is increased, not glass

Burglary Resistance/Forced Entry


Bullet-resistant glass is made by laminating multiple layers of glass and interlayer to form a single multi-ply unit

The glass layers flatten the bullet upon impact

The interlayer provides flexibility and absorbs energy through the unit

Ballistic Protection

Typical Thickness per Level

– Lite cracks as static strength is surpassed

– Laminate deforms inward

– Interlayer absorbs blast energy as it deflects

– Laminate deters accompanying debris

– Energy transferred to frame

– Laminate reacts with an elastic response

– Interior & Exterior protected due to Retention

Laminated Glazing for Hurricane Protection

1. Flying debris breaks glass2. Wind and rain enters a building through

breached openings3. 1% opening on windward wall

1. 200% increase in pressure on underside of roof2. 50% increase in pressure on exterior walls

Structural Failure

Hurricane Applications

• Typically mandated by code and referenced by a standard– Dade County, FL– ICC (IRC, IBC)– ASTM E1886 * E1996

• Most stringent glazing standards in the industry– Impact– Cycling– Structural
