First of all, it should be understood deeply, that there is no frame which provides absolute security and resistance to break-ins. Burglar resistance states how much time (in minutes) a frame can hold against ruptures. Time and tools needed for a successful break-in determine the frame's security properties. Older frames lacked security specifications, as there was no demand for secured frames from the end customers. Older, wooden frames are a classic example of the latter. A current rise in the number of burglaries resulted in increased safety requirements. Nowadays, security properties is an important decision factor for customers.
Therefore, for hinged frames, we recommend multiple locking mechanisms, placed at the perimeter between the sash and the casement . Additionally, sliding doors have to be equipped with internal locks. Apart from windows, it's critical to pick the right entrance door, as it's the spot that gets hit the most during break-ins.
Accordingly, choosing a secured entrance door, like aluminium doors, is vital, for your home's safety. However, not all aluminium doors provide the same security levels; Co-planar doors, stuck with sheet metals, are superior to other choices. A crowbar (or even a very strong kick!) can easily violate a simple panel door. For co-planar doors, the burglar has to violate the door at the alcove point between the sash and the frame, which can take a lot of time.
Lastly, aluminium security entrance doors should always have multiple locking mechanism . In case your door has a fixed part, prefer security triplex glass, which is hard to break.
