How do burglarproof windows work?
Essentially:
Normal locking
Can be opened through cranking
Mushroom head lock
cannot be opened through cranking
01 |
With a so-called “mushroom head lock”
This effective window locking can also be retrofitted and is in principle very simple: Mushroom head and stud are solidly connected with each other if the window is closed and this is inaccessible in such a way that cranking is practically impossible. The number of mushroom heads and the locking pieces play an important role - especially for large windows.
02 |
Glass area solidly glued in the frame
This prevents cranking during the burglary.
03 |
Steel plates in the frame
This makes the drilling with a power drill impossible.
04 |
Drill protection in the handle area
In most cases made of hardened steel sheets, to ensure that the handle gearing cannot be drilled.
05 |
A lockable window handle
However, be aware: Who locks all the windows before leaving the house?
06 |
Material with the high stability
For example, hard wood with a high density to ensure that, for example, fastening screws hold fast optimally.
07 |
Anchoring in the masonry
Prevents that the window can be ripped from its anchoring. For example with special screw anchors - and the right masonry.
08 |
Pressure-resistant back filling
To ensure that the frame cannot be pressed at the wall.
09 |
Probably the safest safety glass of the world
SILATEC safety glass withstands up to 20 minutes, even against ax and sledgehammer - no burglar has lasted this long.
