  • New S12 Security Protection

    1. 1. Designing for Security Protection with Laminated Glass
    2. 2. Presented by: This course is worth 1 hour of Health, Safety and Welfare Credit through the American Institute of Architects Saflex
    3. 3. About Solutia Inc. <ul><li>World Headquarters located in St. Louis, MO </li></ul><ul><li>$3.8 Billion Chemical Company </li></ul><ul><li>World’s largest producer of polyvinyl butyral (PVB) used in laminated glass </li></ul>
    4. 4. Solutia Architectural Brands
    5. 5. Course Objectives What you will learn… <ul><li>Glass Options for Security Protection </li></ul><ul><li>Bomb Blast Basics </li></ul><ul><li>Additional protective solutions with laminated glass </li></ul>
    6. 6. Providing Security Protection & Glass Options
    7. 7. Safety vs. Security Safety = refers to freedom from the risk OR occurrence of injury/loss from natural cause Security = refers to freedom from the risk OR occurrence of injury/loss from the intentional actions of mankind
    8. 8. What is expected of security glazing? Glazing: Must provide an element barrier, excellent optical quality and ease of maintenance Must resist impact, forced entry, bomb blasts, accidental explosions, and ballistic attacks according to national consensus standards Must allow for Building Envelope to be maintained Security glazing is not mandated by the model building codes. The need for security protection and the level of security desired to meet perceived needs are determined by the occupants or owners
    9. 9. Why Design for Security Protection? <ul><li>Burglary, Forced Entry, Ballistic Attacks, and Bomb Blasts and are more and more common </li></ul><ul><li>A burglary occurs every 11 sec in the US </li></ul><ul><li>Bomb Blast events are globally on the rise </li></ul><ul><li>Flying glass shards: 50+% of all injuries from terrorist targeted public building bombings </li></ul><ul><li>Flying or Falling Glass #1 cause of non-fatal injuries </li></ul>
    10. 10. Types of Security Glazing <ul><li>Burglary/Forced Entry Resistant </li></ul><ul><li>Barrier/Forced Exit Resistant </li></ul><ul><li>Bullet Resistant </li></ul><ul><li>Blast Resistant </li></ul>
    11. 11. Types of Security Glazing <ul><li>Standard Laminated Architectural Glass (LAG) </li></ul><ul><ul><li>(1/4” with 0.060” thickness) provides a significant improvement in resistance to attack from a variety of hand held weapons in: </li></ul></ul><ul><ul><ul><li>Residential: Rock, Hammer, Pry bar, Brick, etc. </li></ul></ul></ul><ul><ul><ul><li>Commercial: Sledgehammer, Battering Ram, Chisel, Axe </li></ul></ul></ul><ul><li>LAG cannot be cut from one side deeming glass cutters useless </li></ul><ul><li>Impact resistance (penetration) is directly related to the % of interlayer in the laminate. </li></ul>Burglary Resistance/Forced Entry
    12. 12. Benefits of Laminated Glass FORCED ENTRY
    13. 13. Barrier/Forced Exit Resistant <ul><li>Standard construction multi-ply glass with 0.060” interlayer </li></ul><ul><ul><li>Provides layers of significant barrier to penetration resistance: </li></ul></ul><ul><ul><ul><li>Institutional (i.e.: human, furniture impact) </li></ul></ul></ul><ul><ul><ul><li>Detention Glazing (i.e.: pry tools, safety equipment) </li></ul></ul></ul><ul><ul><li>LAG provides time to for assessment and action. </li></ul></ul><ul><ul><li>Impact resistance (penetration) is directly related to the % of interlayer in the laminate and number of layers of glass. </li></ul></ul>
    14. 14. Types of Security Glazing <ul><li>Bullet-resistant glass is made by laminating multiple layers of glass and thin (0.015”) interlayer to form a single multi-ply unit </li></ul><ul><li>The glass layers flatten the bullet upon impact to slow penetration through unit </li></ul><ul><li>The interlayer holds the glass in place to provide resistance to additional incoming rounds </li></ul><ul><li>The interlayer provides flexibility and absorbs energy through the unit </li></ul>Ballistic Protection
    15. 15. Typical Thickness per Level Check this versus GANA guide 2” .30-’06 Rifle Level 4 High Power – Rifle 1 ¾” .44 Magnum Revolver Level 3 Super Power – Small Arms 1 ½” .357 Magnum Revolver Level 2 High Power – Small Arms 1 ¼” Super .38 Automatic / 9mm Level 1 Medium Power – Small Arms Typical Laminate Thickness Typical Weapon UL 752 Test
    16. 16. Types of Security Glazing <ul><li>Standard LAG (1/4” with 0.030” or 0.060” thick interlayer) </li></ul><ul><ul><li>Provides significant air blast protection through glass retention and debris resistance: </li></ul></ul><ul><ul><ul><li>Glass Retention: Interlayer tends to keep broken glass shards adhered in laminate unit </li></ul></ul></ul><ul><ul><ul><li>Debris Resistance: laminate unit resists penetration from most debris from blast </li></ul></ul></ul>Bomb Blast Resistance
