Bullet Resistant, ArmorResist®

Laminated glass can be designed to resist attacks by a wide range of weapons. There are many standards and test methods available. Almost all of these have two main requirements: (1) the glazing must resist penetration by a specified bullet and (2); the spall or flying shards of glass leaving the rear face, as a result of the impact, must be eliminated. Bullet-resistant laminated glass can meet both of these requirements. It is important to note that ArmorResist® glazing materials are not classified as forced-entry resistant.

Bullet Resistant, ArmorResist® Capabilities

Bullet-resistant glazing is not necessarily resistant to a sustained physical attack or forced-entry; however, some glazing is designed to be resistant to both forms of attack. Products which have been designed to resist both forced-entry and ballistic attacks are to be found in Forced-Entry, ArmorProtect®.

Description [+][-]

Bullet Resistant, ArmorResist® Description

ArmorResist® is a multi-ply laminated glass having multiple layers of glass and PVB bonded together into a monolithic unit. The rear most lite of glass is usually a thin glass that eliminates spall and therefore allows the glass to meet all the requirements of UL 752. This range of products is the most economical and durable range of bullet-resistant glasses manufactured by Oldcastle BuildingEnvelope®.

ArmorResist® Plus is a combination of glass and polycarbonate. PVB and/or a Thermo Plastic Urethane (TPU) is used as the interlayer in this product range. Polycarbonate is one of the toughest clear plastics, having 250 times the impact strength of glass and is used toward the rear of the laminate to flex and absorb the energy of the bullet. The rear face is always exposed polycarbonate with a scratch-resistant coating.

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


Adequate clearances must be maintained to prevent glass damage or breakage as a result of glass-to-metal 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

ArmorResist® and ArmorResist® Plus 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.


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.


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.


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.
