Bulletproof windows Go ahead and shoot..
Home is a protected space - and it should stay that way. Independent of what happens on the outside. Bulletproof windows save life; we always hope that it will never be required.
Safe, safer, SILATEC: If safer windows would be available anywhere in the world then we would present them. SILATEC offers tested and certified protection up to the highest resistance classes. Our bulletproof windows can also be found where only one solution is demanded: probably the safest in the world. For example at the G7 and G20 summits. In embassies. At jewelers, in museums, galleries and in large and exposed mansions anywhere on the globe.
The excellent protection is the result of the interaction of all components: Special frame profiles, reliable safety glass, the hinges, fastening materials and the professional installation.
Bulletproof windows
are beautiful.
Must a fortress also look like a fortress? Quite the contrary. Bulletproof windows can normally be adapted to the architecture in any way and individually; bulletproof windows may even emphasize the individual style of the architect.
You can design bulletproof windows for very large formats: and therefore establish a light-flooded living atmosphere and a breathtaking view of the environment. We present window sizes of up to eight meters, this opens up completely now opportunities: Inside and outside come together, light and air significantly improve your quality of life. Safety can be beautiful.
How bulletproof should your windows be?
And what does your gut feeling say? The attack or threat scenario is decisive for the right protective class. And if you assume - as we do - that our world does not necessarily get safer, then you better select a higher protection class, because a later retrofit is very expensive. When in doubt obtain the assessment of the public authorities - or ask us directly, because we did specialize on this subject for two generations.
You want to know more? With pleasure: The most important differentiation in the threat scenario is between short weapons and long weapons. The short weapons include pistols or revolvers and the long weapons include, for example, rifles or Kalaschnikovs. The resistance classes for bulletproof windows can be found below.
Resistance classes for
bulletproof windows
Nine different classes exist for full penetration resisting windows: from FB1 to FB7 and SG. The same applies to bulletproof glass, they are called BR1 to BR7. The protection effect is valid for the windows as well as for the glass, depending on the resistance class. See table.
| Caliber | bulletproof windows protection class | bulletproof glass protection class | |
| Short weapons | .22 LR 9mm .357 Mag .44 Mag | FB1 window1 FB2 window FB3 window FB4 window2 | BR1 glass1 BR2 glass BR3 glass BR4 glass2 |
| Long weapon | 5.56x45 7.62x513 7.62x514 | FB5 window FB6 window3 FB7 window4 | BR5 glass BR6 glass3 BR7 glass4 |
- 1 The protection class FB1/BR1 has little importance for practical use, because it provides only a little protection effect.
- 2 The protection class FB4/BR4 is often installed. For example in private homes.
- 3 The protection class FB6/BR6 is mainly used where safe protection is required against attacks from a larger distance (long weapon).
- 4 The protection class FB7/BR7 can be found in most cases where terrorist attacks with special hard-core ammunition (which means war weapon ammunition) must be fended off, even from large distances.
Bulletproof windows. from FB1 to FB4 represent short weapons or handguns. The respective glass is designated as BR1 to BR4.
The bulletproof windows FB5 to FB7 represent long weapons, for example, the Nato rifle G36. The glass for this application is called BR5 to BR7.
All of this with little splinter discharge (S) or as a splinter-free version (NS).

Bulletproof windows
against short weapons
Caliber
22 LR
9mm
.357 Magnum
.44 Magnum
Pistols or revolvers have their highest penetration power normally from less than 100 meters. They can be transported more inconspicuous than long weapons.
For this purpose, EN 1063 defines the resistance classes FB/BR1 to FB4/BR4. We recommend the resistance class FB4/BR42, because it also fulfills the requirements of the lower classifications. (FB4 designates the bulletproof windows, BR4 the bulletproof glass),
This resistance class makes you safe against a revolver with the caliber Magnum .44 using “standard ammunition”. Of course, this bulletproof window protects also against smaller calibers, for example, a 9 mm pistol with standard ammunition.

Rifles maintain their penetration power across several hundred meters - it is normally higher than the one for handguns. However, the ammunition makes the difference: War weapons or hard-core projectiles have approximately twice the penetration power than the “soft standard ammunition”.
The EN 1063 identifies the classes BR5 and BR62 for standard ammunition. We recommend BR6 because this glazing also fulfills the requirements of the resistance class BR5 and it only costs little more.

The resistance class FB7/BR7 (as per EN 1063) is applicable if war weapons, i.e. hard-core ammunitions, are used. The class GOST 4 is known in Russia. It also withstands a Kalaschnikov AK 47. GOST 5 is even safe against the dreaded Dragunov.
Hard-core ammunition is specially hardened and it has a penetration power that is significantly higher than standard ammunition. Therefore, glass, window frames and also the walls must be designed safer. Normally also thicker and more expensive.
from me
How are full penetration resisting windows tested?
The projectile will be fired at a right angle to the window frame and the bulletproof glass, because in this manner it develops the highest penetration power. Next, an attempt to shoot at a sloped angle between frame and bulletproof glass is made also between window sash and frame casing.
Bulletproof windows need light weight glass.
Our bulletproof glass with polycarbonate is not only significantly safer than a traditional armored glass window. It is also dramatically thinner and it weighs significantly less. And this is noticeable. The large area windows can be opened and closed much easier and more comfortable especially in modern, open living concepts.
How much do
bulletproof windows cost?
We would be pleased to generate a non-binding cost estimate for you.
The costs depend on the material, the resistance class, format and other factors. Therefore, here are only a few coarse and non-binding guide values (net):
| Protection class | Price incl. glass | NS (no spall) |
| FB2/BR2 | approx. 2,500 €/m² | |
| FB3/BR3 | approx. 3,000 €/m² | |
| FB4/BR4 | approx. 3,500 €/m² | |
| FB5/BR5 | approx. 4,500 €/m² | |
| FB6/BR6 | approx. 5,800 €/m² |
Can windows be retrofitted
to be bulletproof?
Yes. Let’s assume a company headquarter built in the 1960s. The hazard situation has changed and - based on the exposed position of the corporation - the experts recommend bulletproof windows. And not only senior management but also the employees and the visitors must enjoy safe protection.
The bulletproof windows must be integrated completely into the architectural style of the building. Even better if the bulletproof glass is thin and light enough that it can be installed in the existing window frames and that it does not overload the static of the building.
Attachment windows are recommended if you prefer retrofit over exchange. In this case, the bulletproof windows are installed in front or behind the existing windows, which means at the outside facade or inside in the rooms. For example, bullet proof attachment windows can be integrated harmonically in landmarked objects.
Bulletproof windows:
all options.
A bulletproof window must not look like a bulletproof window. Normally it can be fully integrated into the existing architecture. Bulletproof windows are available in all variations: made of wood, metal covered with wood, modern or historic appearance, as filigree sliding windows, sliding doors, swivel windows, pivot-hung windows or as large panorama windows with a width of up to eight meters.
Overview of the
material characteristics
| Wood | Aluminum | Steel | |
| Service life | approx. 40-50 years | approx. 60 years | approx. 70 years |
| Care | Every two years: glazing, every five years: varnishing | no care required | no care required (stainless steel) |
| Ecology | Renewable raw material | high energy production, therefore long service life and good recyclable | recycled versions can be delivered, longest service life |
| Insulation values | good | only in connection with wood | only in connection with supplementary equipment |
| Other benefits | breathable | high weather resistance | Enables very thin profiles, very robust even for public traffic |
Bulletproof windows made of wood
As a sustainable natural raw material, wood has a warm, comfortable look-and-feel, wood windows are also breathable. With the special texture, the haptics and optics of the surface, bulletproof windows made of wood offer characteristic design elements. As a matter of principle, wood - as all other materials - can be integrated to match any architectural style. However, the living material needs frequent care (see table above).
Bulletproof windows made of
wood and aluminum
These bulletproof windows combine two worlds: the natural beauty and comfort of wood and the elegance and easy care of aluminum. They can also adapt perfectly to any residential style and can, as all of our window types, be customized: exactly to your desires and needs.
Bulletproof windows made of aluminum/steel
These bulletproof windows have an even longer service life than wood windows and they do not need any care. The relatively high energy demand during the production is counteracted by easy recyclability and low weight. This is a benefit during the transport, but also during daily use: the larger the bulletproof window, the more enjoyable the low weight.
Bulletproof windows as filigree sliding elements
The room gets an additional width and bounteousness due to filigree sliding elements: light and air generate a totally new quality of life. The sliding elements can be operated manually or electric. In an open condition, the windows can disappear invisible in a wall pocket, and inside and outside integrate since the threshold can be designed totally flush with the adjacent areas.
Bulletproof windows:
two major factors.
First: the weight. The windows can be opened and closed more easily the less the bulletproof windows and the glass weigh. Bulletproof glass by SILATEC combines different impact resisting and extremely resistant material to a wall of glass. Despite this fact, it is surprisingly light weight.
Second: the transparency. The traditional armored glass window is not only significantly less safe. You can also identify it because of its green tint. Of course, attackers also. Bulletproof glass by SILATEC in contrast is color-neutral and transparent: the attacker does see what waits for him. And you see the blue sky not in green, but exactly as blue as it really is.
