Bullet-Resistant Glass (BRG) can be ideal in certain situations. It is transparent, allowing the window to remain in use, and since it is a permanent installation, it is always ready to protect. However, it can have some severe drawbacks:
1. Depending on the protection level needed, BRG can cost between $25 and $100 per square foot just for the material; however, it is not a drop-in replacement for a conventional window design. To convert unbuilt construction or develop a retrofit for it in older construction can easily make the cost reach $400 -$600 per square foot once you consider:
2. It is heavy, weighing between 14 and 30 pounds per square foot. This can make it challenging to add as a retrofit as this weight may exceed the structural ratings of the building walls. It is also difficult to transport, handle, and install. This is especially true in multi-story buildings.
3. A converted BRG window can no longer be used as an egress.
4. It is impractical to install as a door, as it would make the door extremely heavy, making it cumbersome to open and close and it would prohibit the use of conventional hinges to support the weight (adding more cost). Glass in a door is really only practical when limited to small portal windows.
Using a BBP fabric shade can resolve some of these issues:
A proprietary fabric design, the core of which is a custom weave of Kevlar® para-aramid fiber, the same type of fiber used in the anti-ballistic body armor used by the military and law enforcement. Unlike body armor, our design does not rely on the strength of the Kevlar fibers alone to stop the projectile. The patented mounting design acts as an energy-dissipating system, which enhances the shade’s ability to absorb the impact of the bullets while transmitting less stress to the construction around the window or door.
Great care was taken during the development of the product to make the installation easy enough for a novice to handle it. The product installs with no more effort than installing common residential window shades would take.
However, if the area around the window/door has any kind of complex trim or casing, this could complicate the installation. If this is the situation, please include pictures of the area with your quote request so that we can examine the surrounding structure. We may determine a highly customized installation package is required or even recommend you to one of our installation partners.
If there are adjoining window frames separated by a mullion or section of the wall that is not likely to have solid enough construction to stop a projectile on its own (see image below), two options exist to allow for the protection of these areas:
The product is similar in cost to body armor as the ballistic core is very similar. Our product also includes oversizing the coverage area by several inches in each direction to protect against rounds that are fired at the window or door at an angle. In addition to this, there are the costs for the mounting hardware and the motor, which can vary a great deal depending on the installation.
It is critical that the fabric is either stored rolled up on the rod it came with, with no bunching, wrinkles, and misshaping to the roll, or stored completely flat. Wrinkles and creases can reduce the strength of the Kevlar. If you do happen to store it incorrectly and it develops a permanent crease, DO NOT iron the fabric. Let the fabric rest completely flat using weights to flatten the wrinkles with gentle pressure.
Yes, but international shipments may use alternate material sources.
The term “bulletproof” is often misused when referring to flexible fabrics used in body armor or for glass used in buildings and specialty vehicles. Bulletproof vests or bulletproof glass do not really exist by the definition of being able to stop ALL bullets, ALL of the time. The term the ballistic industry prefers to use is “bullet-resistant”. This means the product can resist the penetration of specific bullets based on its rating, and up to a certain number of impacts. Given enough firepower, all body armor, Kevlar fabrics, or bullet-resistant glass can eventually be overcome.
So, just like body armor and glass, the BBP products are rated as being bullet-resistant for certain calibers, being certified to one of the most common standards UL752.
BBP not only passes the certification tests, but has done so with a significant margin. In the armor industry, the material strength is determined by one of two evaluation methods: V0 or V50 testing. With V0, the product is tested to determine the bullet velocity at which 0% of the rounds penetrated the material (the material will stop everything). Given the variability of the testing, this method is not generally deemed conclusive in determining the strength of the material. In V50 testing, the rounds are fired at higher and higher velocities until they begin to penetrate, increasing until a point at which 50% of the rounds at least partially penetrate the material. This type of testing is done to understand the margin by which the product is passing the standard and in routine testing, determine with greater confidence how the materials are performing in ongoing production, thus ensuring the product will work as advertised.
UL 752 Requirements
Not currently. There is no issue with passing any of the European standards, but because product certification is a long process, and there are over dozen major standards and quite a few more minor standards, at this time only the UL standard has been tested. For international use, it will be up to the customer to determine if certification to the UL standards defines the appropriate fitness for use in their country.
The product has been tested with .45 ACP firing at 700 rpm and 9mm firing at 1100 rpm. In both test cases, there were no penetrations through the fabric. However, the product has only been certified up to the UL 752 Level 3 standard and that is the limit of the product guarantee.
In one informal test case, 200 rounds of 9mm ammunition were fired into the sample without any penetrations through the fabric. However, the product has only been certified up to the UL 752 Level 3 standard and that is the limit of the product guarantee.
At this time, the design is limited to handgun fire.
After the material has absorbed the impact of actual live rounds, it is no longer certified as the fibers around the impact point will have been weakened. Given the amount of variation of damage that could exist, it is nearly impossible to allow the product to be certified for a second, separate attack.
Once your shades have had any kind of impact from live rounds, please contact us to discuss what components must be replaced for the shades to maintain certification.
The product is designed so that the window shades can be deployed daily and used as a normal window treatment. Life testing shows that it will withstand daily use for a period of at least seven years.
The product is designed only for interior use.
The fabric is warrantied to remain viable for at least seven years when consistently stored at a temperature range of 32 to 120° F and humidity up to 85%. It is also critical that the polyester cover fabric remains completely intact and in good condition. To maintain the certification during this allotted time period, the fabric must be routinely inspected for any signs of damage such as creases in the Kevlar, as well as tears or worn spots in the cover materials that would expose the Kevlar to sunlight (which degrades its strength).
Custom solid colors or even prints are possible with the polyester cover fabric. Please contact us directly with your requirements.
Changing the polyester cover material to a different type of fabric is not possible. The polyester is a special weave that meets very specific requirements for the design to maintain certification. However, it is possible to laminate other materials to its surface, such as designer fabrics.
It is critical that the cover fabric that is shipped with the product is never modified. Doing so can significantly affect the strength of the Kevlar fabric.
The fascia face can be customized to add a fabric covering that complements the cover material of the shade itself. Please contact us with your request.
The plastic end caps for the fascia are available in only colors of beige, gray and white. But since they are only cosmetic coverings and serve no structural purpose, they are the only items that we can allow the customer to customize on their own by painting or adding material to the outside surface. However, they cannot be removed or replaced entirely as doing so may expose the mechanical shade components to unintended wear or damage.
The standard product cannot be customized for this, but please discuss your needs by contacting us as there may be other options that we can suggest.
There are several motor options from two major brands in the window treatment market. These motors are available in 120/220 VAC, 24VDC, and battery powered.
The motor wiring can be plugged into the wall or directly wired to a power source.
The motorized version can be actuated with a handheld remote, wall mount, from a central control system, a security system and a variety of alarm or sensor equipment.
To meet certification, it is required to attach the upper and lower brackets directly to wall studs, with at least 1” of screw engagement into solid pine wood, per the installation instructions. If the particulars of your window/door architecture do not allow for this, a custom design may be possible; please contact us directly if this is your need.
If the trim or area around the window/door has some complexity that inhibits normal installation, please include pictures of the area with your quote request so that we can examine the surrounding structure. We may determine a highly customized installation package is required or recommend you to one of our installation partners.
Yes, we have an ever-expanding network of installation partners that can handle the installation and even take the initial measurements. Please contact us directly with your request and we will put you in touch with one in your area.
To maintain certification, the installation must be completed according to our instructions and with our supplied hardware. If there is an issue with using the hardware provided or if it was damaged during the installation process, please contact us for replacements.
The product is warranted to be free of material or workmanship defects for a period of one year from the date of initial purchase. This warranty includes the cost of repairing or replacing materials (at BBP’s discretion) and any shipping costs involved. Outside of this, the cost of repairs will be handled on a case-by-case basis. For more details, see our full disclosure here: warranty and guarantee.
The product is guaranteed to meet the criteria certified by the UL 752 Level 3 or Level 2 testing in a single attack from a handgun (an “event”). This guarantee extends for a period of seven years from the date of manufacture. Due to the numerous variables that can be associated with an event (proximity, angle of attack, custom loaded rounds, rate of fire, number of rounds fired, multiple guns used simultaneously, successive events…), it is not practical to test and guarantee the product for all the possible threat variations that could exist. It is up to the customer to review the certification to determine if the product is appropriate for their needs. After a single event, it is recommended that the product be replaced in its entirety as it will no longer be certified to the UL 752 standard and the product guarantee will be void. For more details, see our full disclosure here: warranty and guarantee.
As each product is custom-made to the dimensions submitted, there are no returns or refunds allowed once the order has been started.
