Aluminium security windows from Armortex
April 17, 2019
Bullet-resistant security windows are comprised of a composite system of alternating glass and polymeric layers – typically polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). These dissipate the force of an impacting projectile before it penetrates through the other side of the window. Bullets are captured within the composite, providing effective protection for personnel from a variety of small arms fire.
The added weight of additional materials in sequential layers presents a distinct challenge for the installation of bullet-resistant glass. They require more robust window frames that are themselves resistant to lateral penetration from ballistics, without posing an unfavorable risk of bullets ricocheting and causing harm to bystanders.
Benefits of Aluminium Security Windows
Aluminum is a very favorable material for constructing the frames of security windows due to its comparatively low cost and good strength-to-weight performance. It is more cost-efficient than steel alloys and can be less invasive to install due to the lower weight profiles of aluminum security window frames. Although lighter than steel, aluminum security windows are still heavyweight products tested to the highest levels of ballistics resistance established by the Underwriter’s Laboratory (UL).
Armortex aluminum security windows boast the added benefit of a non-ricochet material incorporated into the design which allows the capture of projectiles. This strengthens a potential weak-point and reduces the risk of lateral penetration into a protected environment.
Although protection and ballistic-resistance is the primary concern of security windows, they are often installed to perform a dual functionality. Aluminum frames and fixtures enable the design of a broad range of security windows suitable for active commercial environments, to ensure that security and profitability are never at odds with one another. Some of the designs available from Armortex include:
- Fixed and clamp-on aluminum security windows;
- Thermally-broken aluminum frames for outstanding temperature regulation in cold climates and outdoor applications, such as ticket booths;
- Speak through aluminum security windows feature natural voice propagation or an embedded voice transmission device to enable easy communication from one side to the other;
- Transaction frames may comprise a small aperture beneath the glass, or a hinged or sliding panel that enables restricted access from one side of the security window to the other.
