Vulnerabilities in Standard windows

Forced entry through a window is a common entry point for burglars and potential attackers. Homeowners may invest significantly in secure doors, but weak glass can make those investments near pointless. Double and triple pane glass may sound stronger, but even toughened glass can easily shatter – in fact its safety features (limiting sharp shards from forming) makes it more susceptible to sudden bursting from attack by blunt object.

Because standard windows – unlike doors, or walls – are extremely easy to shatter open they remain as one of the top risks for unauthorized entry into a home.

Protection Level Comparison

Residential ballistic glass generally ranges in protection levels between the eight Underwriter Laboratories ballistic specifications listed in UL 752. These indicate the caliber type, velocity and number of rounds fired at a square foot area of the glass.

Most home owners typically work with Levels 1-3 when covering large portions of their home’s exterior. These levels cover handguns. Level 1 residential ballistic glass stops 3 rounds from a 9mm handgun. Level 3 stops three rounds of one of the most powerful handguns on the market: the famous .44 Magnum.

The higher rifle ballistic levels will be more often employed for safe rooms, though a sizeable number of clients will utilize it for their entire home exterior too. Rifle levels comprise Levels 4, 5, 7, and 8. Level 6 is the odd exception – it stops 9mm rounds like Level 1, but at a faster speed and high quantity. This is to stop bullets shot from a weapon like an Uzi.

Take a look at the UL 752 diagram to the right to see more detail. Our team can give you several options based on your specific situation to help you figure out which ballistic windows are right for your home.

Commercial vs Residential Ballistic Windows
Bullet shatters in ballistic glass

Installing bullet proof glass for home windows is different than installing glass for commercial uses. Bullet resistant glass can be found in many commercial locations from gas stations to banks, and it is even currently being installed at as a security measure at the Eiffel Tower. Commercial locations are designed to serve certain functions, whether it be transacting money or selling convenience items. A home on the other hand, should be a relaxing, beautiful place for a family to live in.

Bullet proof home windows must therefore incorporate beauty and elegance as much as they incorporate security. Bulky and cumbersome simply will not do. Of primary important is of course being able to clearly see out of the window in question. But the system used for the frames is also important. Finally, the right type of locking should be incorporated as well. All of these factors depend on the client’s preferences and the specific application, such as whether it is located in an apartment or home.

But a home also has a different security needs. A home may have multiple locations that can be targeted for entry and may be often empty and without public deterrence. Our specialists can help you identify the most important locations for installing bullet resistant glass.


Additional Installation Details

Our windows are much stronger and therefore thicker and heavier than typical shatter resistant glass but the basic installation principles remain the same.

You don’t need to be a large company to incorporate ballistic windows into your home. While the framing requirements do differ somewhat, ones home does not need to be augmented greatly to incorporate this security feature. They can convenient be installed into a new or an existing residence.

The thickness of the glass (usually comprised of multiple, fused layers) ranges depending on whether the homeowner wants axe resistant, handgun resistant or assault rifle resistant protection levels. But the frames general are quite similar throughout, although the overall unit can vary in weight by 20-50%.

Our windows are made-to-measure, so it is important to first get accurate rough opening measurements prior to production. The planned measurements will be listed on detailed shop drawings for the client or contractor to sign off on prior to officially releasing for manufacture.

Once the windows are completed, they arrive on location to the residence. The windows arrive fully assembled. Generally the glass is temporarily removed for installation. This allows the contractor to first install the frame into the opening, without the weight of the glass making it more difficult. Especially for an operable window, installing the frame plumb, level and square is very important.

Our window frames has specialized steel frames built in to them that offer easier installation and greater security.
