Forced Entry, ArmorProtect®

Introduction

ArmorProtect® is used where glazing is required to resist penetration for some considerable time, typically measured in minutes rather than seconds. These types of attacks are usually planned, sustained attacks using more than one type of weapon. Oldcastle BuildingEnvelope® offers three types of protection: ArmorProtect®, ArmorProtect® Plus and ArmorProtect® Max.

    • Several test procedures evaluate glazing performance in the medium and maximum security institutional setting. Each one specifies the specimen size and condition, the opening size that constitutes failure, the weapons used and the number of impacts and sequence of attacks using those specified weapons. The test standard section provides a summary of the various test methods. It is essential that the design professional has a full understanding of the complete test protocol.

    Description

    Forced Entry, ArmorProtect® Description

    • ArmorProtect®
 ArmorProtect® burglary and attack-resistant/ institutional laminates offer improved security and provide unobstructed vision while eliminating the confined look of bars and metal screens. Typical applications include penal institutions, psychiatric hospitals and police stations. In addition, institutional laminated architectural glass provides increased protection in other high-security locations such as computer centers and sensitive research centers.

      ArmorProtect® Plus
ArmorProtect® Plus prolonged attack-resistant security glazing laminates contain the toughest plastics available, often containing multiple layers for maximum forced-entry resistance. Typically, these products are used in jails, correctional facilities, embassies and other secure establishments. ArmorProtect® Plus includes a family of multi-ply laminates containing one or more core layers of polycarbonate, often called glass-clad polycarbonates. Polycarbonates offer the strongest available clear plastic and have 250 times the impact strength of glass.

      ArmorProtect® Max
ArmorProtect® Max are lightweight laminates having multiple layers of polycarbonate containing no glass and offering extreme levels of forced-entry protection. These products also offer ballistic protection. Sheets of aliphatic urethane are used to bond the layers of polycarbonate permanently together. The external faces of polycarbonate are protected with a mar-resistant hard coating to provide durability. They are not recommended for external use.

    Installation Guidelines

    Bullet Resistant, ArmorResist® Installation Guidelines

    • These guidelines are to be used in addition to, and in conjunction with, the guidelines in the latest edition of the Glazing Manual published by the Glass Association of North America and Oldcastle BuildingEnvelope® Glazing Instructions. These should be included as part of the glazing specifications. Failure to follow these guidelines may result in voiding of the warranty.

      Setting Blocks

      All laminated glass should be installed on setting blocks positioned on the lower edge at the quarter points. The setting block should have a Shore A durometer of 85±5, support the entire thickness of the glass and be 0.1" long, per square foot of glazing, but not less than 4" in length. Ensure that the setting blocks are manufactured from Santoprene, Silicone, EPDM or any other material compatible with silicone and the rest of the glazing components. Pay particular attention to compatibility when the laminated glass contains a
      polycarbonate.

      Clearances

      Adequate clearances must be maintained to prevent glass damage or breakage as a result of glass-tometal contact. A minimum of a 1/8" face clearance should be maintained using a cushioning material. Edge clearance should be a minimum of 1/4"; however, due to the expansion of polycarbonate, any laminate containing this material should have a 1/16" edge clearance per foot of glass length. To reduce in-service breakage, avoid excessive clamping pressures, especially on thin annealed glass.

      Edge Engagement

      All forced-entry and bullet resistant glass must have a minimum of a 1" edge engagement. Clearances and setting block allowances are in addition to this engagement. Any reduction in this edge engagement can cause the performance of the product to be reduced and the test certificate may no longer be applicable.

      Weep System

      The edges of laminated glass must not be exposed to standing water. All framing systems must be designed to accommodate a reliable weep system, as no cap seal is 100% reliable. In addition, it is extremely important that any cleaning solutions used on either face of the glass be allowed to drain out of the frame. It is the responsibility of the designer and the installer to ensure that the weep system works correctly. Do not glaze any laminated glass in a system without adequate drainage.

      Sealants and Caulking

      An appropriate sealant should be used to seal the glazing to the frame. Sealant and caulking manufacturers regularly change their products' raw materials. Therefore, it is essential that the installer checks with the appropriate manufacturer for compatibility of any product, before use. This is particularly important for security glazing containing polycarbonate, as some solvents used in sealants can cause crazing and ultimate failure of the product. This warning also applies to any varnishes, primers or paints used on the framing system. These finishes should be allowed to fully dry before glazing commences.

      Threat Surface

      Most bullet-resistant glazing products and some forced-entry products are not symmetrical and have a threat side, attack face or impact face. All glass of this type supplied by Oldcastle BuildingEnvelope® is shipped with a removable label specifying the impact face. This side MUST be installed toward the threat side. Failure to do this can seriously affect the ability of the product to resist the specified threat. This label should be left on until final inspection and/or sign-off occurs.

      Storage

      Shipments should be scheduled so that glass is stored on the site for a maximum of 30 days. If the glass is to be stored for longer than this, it should be removed from the construction site to a controlled environment. When on the site, store crates indoors and keep them dry. Ensure that the stored glass remains above the dew point at all times; otherwise, condensation and staining can occur. Protect the
      crates from exposure and possible damage from the practices of other construction trades.

      Handling

      Only remove the glass from the crates when it is ready to be installed. Remove glass from the front of the crate–never by sliding to the side. On security glass with exposed polycarbonate, pay particular attention to this face. Never allow glass to rest on uncushioned surfaces. When exposed polycarbonate is supplied with a protective removable sheet, this must be removed immediately after the installation. Never allow the sun to bake this protective film on to the glazing. Never allow anything to rest against the glass. DO NOT install any glass that has been damaged, however slightly. Even small cracks at the edges can ultimately "run" due to thermal expansion while in service. Oldcastle BuildingEnvelope® does not warrant glass breakage.

      Cleaning

      Do not expose the edges of any laminated glass to organic solvents, acids or any cleaner containing ammonia, which can react with the plastic components. Once the glazing is installed, the glazing contractor should ensure that the glazing is protected from possible damage caused by the construction practices of other trades. Take particular care during the initial cleaning, especially if the surfaces are severely soiled. Never attempt to remove dry deposits. NEVER use a sharp blade or scraper to remove deposits or clean
      the glass.

      First flush with water to soften and remove as many contaminants as possible. Then use a clean squeegee to remove excess water, ensuring that abrasive deposits do not get trapped between the squeegee and the glass surface. Then use a mild nonabrasive, nonalkaline cleaner and a soft, grit-free cloth to clean the glass. Rinse immediately with water, removing excess water with a squeegee.

      For routine cleaning, a mild soap or detergent, with lukewarm water, can be used with a clean, grit-free cloth. Dry the surface immediately and never allow metallic or hard objects, such as razor blades or scrapers, to come into contact with the glass.

      Cleaning Exposed Polycarbonate

      All exposed polycarbonate has a mar-resistant coating; however, extra care must be taken to avoid scratching or other damage. Do not use any abrasive cleaners or solvents. Wash with a mild detergent and lukewarm water, using a clean, grit-free cloth. Rinse immediately with clean water and dry with a chamois or moist cellulose sponge to avoid water spots. Fresh paint, grease and smeared glazing compounds can be removed using isopropyl alcohol. Afterward, wash with warm water and a mild detergent, as noted above.
