Burglar almost always select the perceived weak point of the house: the windows and doors. That is why you should give the burglar what he deserves - a burglarproof RC2, RC3 or RC4 window. With the above and with the safest safety glass of the world, we have successfully warded off thousands of burglary attempts, everywhere in the world. With an increasing tendency.
By the way: An alarm system does not really protect against burglaries. Because only the mechanical burglary protection can delay the burglar - the longer the culprit is delayed the more safe is the object.
Our experience shows: Really burglarproof windows starting with the resistance class RC3 windows. The lowest resistance class RC1 offers no burglary protection, RC2 windows offer at least a basic protection.
RC3 windows offer approximately five, RC4 windows even ten minutes burglary protection. In our experience, this is the most frequent selection for the securing of private residences. In contrast, RC5 and RC6 windows are qualified for especially exposed risks, for example, for nuclear power plants or military facilities.
Zero burglary protection,
not recommended
Basic recommendation for mansions with a resistance time of about one to three minutes against amateur culprits with SILATEC P6B glass.
Our recommendation for an effective burglary protection in mansions: about five minutes resistance against practiced culprits in connection with SILATEC P6B safety glass.
Our recommendation for the perfect burglary protection. About 10 minutes resistance against experienced burglars in connection with SILATEC P8B safety glass.
Normally over-dimensioned for private residences, especially with respect to the economic viability. Approx. 15 minutes resistance time in connection with
Clearly over-dimensioned for private residences, rather for extremely exposed risks such as nuclear power plants. Approx. 20 minutes resistance time in connection with SILATEC P8B glass, also against experienced culprits with powerful electrical tools.
You must make no compromises for burglarproof windows: We present them in all possible forms, colors and materials. They can be completely integrated into the existing architecture. We are producing the glass with a width of up to eight meters and this largeness can additionally increase the value of any building.
Burglarproof windows are available in many variations: in a historic or in a modern form, as fine and filigree sliding doors or as room enhancing and view opening panorama windows. As fixed glazing, turning, swivel-tilt, swing-casement, sliding, escape, roof, lattice or two-leaf French-casement window.
| 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 |
Wood gives a warm feeling and as a sustainable natural raw material it is also breathable. Wood also feels natural when touched, the characteristic texture and optic of the surface can additionally emphasize the style of the architecture but it can also be understated in a refined way. However, as a natural material it requires frequent care (see table above).
These burglarproof windows combine natural noblesse and the living comfort of wood with the straightness and the ease of care of the aluminum. They are recommended everywhere where the weather has a strong impact or where the burglarproof windows are difficult to access - repainting on the 7th floor can be very expensive. We can produce these burglarproof windows also exactly in accordance with your requirements: with a width of up to eight meters, and in all forms and colors that you want.
These burglarproof windows have an even longer service life than wood windows and they do not need any care. For this purpose, we also deliver forms, colors and formats exactly as you want it. You will enjoy the daily opening and closing because our burglarproof windows made of aluminum are surprisingly light weight - this can especially be experienced when using large formats. The energy consumption during production is relative high, but we ensure a good recyclability.
Large format sliding doors open the room. Optically with the flooding daylight, but also factual with the incoming and exiting air. The room becomes even wider, bounteous, and the outside and inside become one - thresholds will not be an obstacle because they will be installed totally flush with the adjacent areas. The filigree sliding elements can also be actuated electrically and the opened windows can disappear in a wall pocket. SILATEC safety glasses strengthen the construction significantly as our burglar tests show.
The official experts state it clearly: The mechanical burglary protection has priority over the electronic protection. “Electronic burglary protection” covers, for example, the alarm system, security cameras, etc. And these devices only report the burglary, however, they do not prevent it.
In addition: Alarm systems may even encourage burglars. Because the culprit sees, that there are valuables to be stolen. In contrast, “mechanical burglary protection” provides burglarproof windows and burglarproof glass and only those objects can hinder the potential culprit against entering the building. The alarm system cannot replace this protection, however, it can supplement it. Also to be recommended: Trained guard dogs. Ideally one for the inside and one on the outside.
Test standards for burglar resisting windows offer a first orientation. But: Are there any burglars that conform to the standards? Let us look at RC2 windows. Based on the test standard it offers three minutes of resistance. However, in practice it is already broken open in about one minute. Why? If the burglar finds that he cannot open the RC2 window, then he attacks the glass. And now it progresses fast: Because the P4A glass that the standard specifies is broken within ten seconds! The standard does not even test the glass.
In addition: The test engineer may during the test only use small tools such as a screwdriver. However, if the real burglar comes with a larger tool, then the RC2 window is quickly opened. It is similar for burglarproof RC3 and RC4 windows: The glass is also not tested here. While the RC3 resists for five minutes, the glass that the standard specified - namely P5A glass - is already destroyed after 15 seconds. The RC4 window achieves already ten minutes, the glass only 30 seconds (traditional P6B).
| SAFE glass | Glass NOT tested | |
SILATEC | Resistance time according to the standard: about 3 min. P4A glass is specified according to the standard. Only approx. 10 seconds! | |
SILATEC | Resistance time according to the standard: about 3 min. P5A glass is specified according to the standard. Only approx. 15 seconds! | |
SILATEC | Resistance time according to the standard: about 3 min. Traditional P6B glass is specified according to the standard. Only approx. 30 seconds! | |
Retrofitting represents no problem in case of the fixed glazing. For pivot-tilt windows normally after construction year 1980. Normally we exchange glass and fittings and equip these with a mushroom head lock. Burglarproof attachment windows can be integrated in case of older or even landmarked objects: In this case, the burglarproof windows are installed in front or behind the existing windows, which means at the outside facade or inside in the rooms.
Test standards are good, but the actual experience value from practical use are even better. The local condition, the individual risks at the location as well as your personal hazard potential are always decisive for a recommendation. When in doubt, ask your local public authority or contact us.
| Safety window | Burglary protection | Burglary protection | Applications |
| RC1 windows | no burglary protection | no recommendation | no recommendation |
| RC2 windows | approx. 1 to 3 minutes in case of amateur culprits | SILATEC P6B | Basic protection against private residences |
| RC3 windows | approx. 5 minutes in case of practiced burglar | SILATEC P6B | effective burglary protection for private residences |
| RC4 windows | approx. 10 minutes in case of experienced burglars | min SILATEC P6B, better SILATEC P8B | perfect burglary protection for private residences |
| RC5 windows | approx. 15 minutes in case of practiced burglar | min. SILATEC P8B | normally over-dimensioned for private residences |
| RC6 windows | approx. 20 minutes in case of experienced burglar | min. SILATEC P8B | for extremely endangered objects, for example, nuclear power plants |
The highest number of safety windows in private residences are RC3 and RC4 windows. In combination with SILATEC P6B or P8B glass, they offer effective or even perfect burglary protection. RC2 windows still present basic protection, while RC5 and RC6 windows are normally over-dimensioned for private residences.
Namely by the burglars themselves. We experience about 100 burglaries per year, or better: Burglary attempts, and this since more than 20 years. Based on this, we develop the safest safety solutions in the world; this means burglarproof windows up to the highest resistance classes. What does the experience show? As a matter of principle, the following is valid: The higher the expected booty, the higher the effort, on the other hand: the longer the burglary lasts, the higher the probability that the attacker will give up.
And it should not be forgotten: to be able to hammer for only five minutes with an ax on a pane needs an almost inhuman physical condition. Other major questions: How high is the discovery risk? Is the burglarproof window covered or clearly visible? How does the burglar proceed and what tool does he use? How are the escape option and how fast are the action forces at the location? Is this a residential area or a vacation home? By the way: Burglary attempts in vacation homes take place if the residents are at the location. Because the promise of booty is significantly higher.
The test standard does in part not test the glass - and glass is specified that can be destroyed quickly! The burglar is in this case quickly in the building. This is comparable to a tested and certified security rope for mountain climbing - with a brittle carabiner.
Therefore, the RC2-RC6 windows are only really burglarproof when using SILATEC glass: safe frame, safe glass. By the way, one is by all means more careful in other standards for windows and doors: the door frame as well as the glass will of course be tested for burglary resisting escape doors or panic doors and also for full penetration resisting windows.
| Tested frame/resistance time | Glass not tested/resistance time | Recommended glass/resistance time |
| RC2 window/3 minutes | P4A glass/only 10 seconds! | SILATEC P6B2/5 minutes |
| RC3 window/5 minutes | P5A glass/only 15 seconds! | SILATEC P6B2/5 minutes |
| RC4 window/ten minutes | Traditional P6B glass2/only 30 seconds! | SILATEC P8B/approx. 20 minutes |
| RC5 window/15 minutes | Traditional P7B glass/less than one minute!1 | SILATEC P8B/approx. 20 minutes |
| RC6 window/20 minutes | Traditional P8B glass/only approx. one minute!1 | SILATEC P8B/approx. 20 minutes |
Caution:
The standard for RC1-RC4 windows: tests only the window frame - but not the glass! The glass specified by the standard is already destroyed after a few seconds! See table above.
The burglary protection is advantageous also with respect to the financial performance of your property. Respectively equipped windows do not only provide a good feeling and an increased quality of life but also a measurable value increase of the building. Finally, safety questions become increasingly more critical value factors. They can also be an exclusion criterion during the sale if a burglarproof window can only be retrofitted with difficulties. Because safety is mandatory for upscale residences.
“RC” is the abbreviation for “Resistance Class”. The previous abbreviation “WK” is therefore obsolete.
Based on this standard, burglarproof windows are categorized ascending from RC1 to RC6 windows. RC1 windows offer the smallest, practically no burglary protection, RC6 offers the highest protection - and this is also reflected in the price. While RC2 windows offer an acceptable basic protection, RC3 and RC4 windows offer a meaningful and effective burglary protection.
“RC” means “Resistance Class”, the class in which the window will be tested. Meaningful burglary protection starts with the resistance class 2, i.e. RC2, RC3 and RC4 are found most often for private residences and RC5 and RC6 are used for especially exposed risks.
RC2 N windows are less burglarproof than RC2 windows, because normal window glass is installed here. This can be broken by throwing a rock and the burglar is in the building in a few seconds.
Burglars try to crank windows open. For example with screwdrivers, wedges, crowbars. Or they break the glass pane.
An unlocked handle is a safety risk, for example, if the culprit can hammer a hole in the glass and afterwards simply opens the handle. However: Who locks all the windows before leaving the house? And opens all again? More meaningful than lockable window handles is resistant safety glass.
Roller blinds do not offer any burglary protection.
Of course, we deliver burglarproof windows also with an alarm system. However, only the mechanical resistance can hold the burglar really back. With a safe window and a safe glass.
Of course. This is a special construction with many tons of weight and special locks. Based on the extreme hazard potential, even the highest class - i.e. RC6 windows and doors - does normally not provide adequate protection.
Zero burglary protection.
Basic protection. Based on the standard, the RC2 window must withstand an amateur thief for three minutes - however: a practiced burglar breaks the RC2 window already after approx. one minute. The glass pane breaks already after 10 seconds! Pardon?
Yes, as mentioned above: The glass is not tested by the standard, only P4A glass is specified. And this can be broken within 15 seconds.
If RC2 widows are used, then SILATEC P6B should be used because it withstands an attack for ten minutes.
Effective burglary protection for private residences. The standard specifies that RC3 windows must withstand a practiced burglar for about five minutes; even against a massive crowbar. However, the glass is not tested, only P5A glass is specified. This can be broken in 15 seconds even by unpracticed culprits. Therefore the recommendation: SILATEC P6B glass - it withstand for more than five minutes, exactly as long as the window. Equipped in this manner, RC3 windows offer a balanced relationship between costs and burglary protection.
Perfect burglary protection for private residences: The resistance duration for RC4 windows is approximately twice as long as for RC4 windows - which is also reflected in the price. An RC4 window delays even an experience burglar with chisel, crowbar, ax or power drill for approximately 10 minutes.
The standard does not test the glass even for RC4 windows! The standard only specifies normal P6B glass - and that is already broken after about 30 seconds! In contrast, SILATEC P6B glass offers already five minutes protection, even better qualified is SILATEC P8B with 10 to 20 minutes protection. Frame and glass should be equally safe.
Exceptional burglary protection for private residences: RC5 windows withstand a total of 15 minutes even against experienced culprits - against electrical tool, e. g. power drill, jigsaw or saber saw and angle grinder with a disk diameter of 125 mm. The glazing is tested for this application. The recommendation: SILATEC P8B with up to 20 minutes. The RC5 window is normally over-dimensioned for the use in private residences.
The highest burglary protection for private residences: More than 20 minutes protection even against experience culprits with powerful electrical tools, e. g. power drill, jigsaw or saber saw and angle grinder with a disk diameter of 250 mm. The glazing will also be tested for this application. Same recommendation: SILATEC P8B with up to 20 minutes resistance duration. RC6 windows are rather qualified for extremely endangered objects like nuclear power plants.
