"System 7" has several unique characteristics, rendering it superior to ordinary double glazing. The materials employed in manufacture, the profile, the glass, fixtures and fittings all have superior security properties.
A standard profile has a thickness of 4 cm, the "System 7" profile has a thickness of 7 cm extruded in a moulded fashion for maximum strength. This unique moulding of the profile gives it phenomenal strength; it is virtually impossible for would-be intruders to bend or force open in any way.
A standard glazed unit or door panel has an overall width of 18 mm. The "System 7" units have an overall width of 24mm; this not only adds security but also provides a superior thermal break.
Standard 3-point locks function by hook locks that drop into position. "System 7"windows and doors are fitted with geared-rotary locks which, due to their geared mechanism are much more secure.
Locking
For the purpose of added security we recommend fitting doors and windows
with 3 point locking mechanisms.the lock we fit has a geared locking action
which allows it to operate smoothly.this gearing makes it almost impossible
for would be intruders to drive a locking point out of location, and all
3 locking points are independent of each other; therefore if one point
fails the other two remain located.on sliding windows and doors a centre
lock is available for extra security. A centre lock consists of a hardened
steel pin which neatly loates within the two meeting styles of the sliders.they
are key locking and cannot be breached by would be intruders.
Options:
Crystal now offers a range of security options to upgrade your window
and door security including concealed key barrel/ lock cores as well as
the very highest security locking barrels (drilling of key barrels by
World be intruders is becoming more common place).
All Crystal doors in aluminium or PVC come with high security hinges and
high security lock barrels as standard. An upgrade is available on barrel
locks which by use of hardened steel prevents barrels from aging, drilled
out or knocked out.
On side hung windows in aluminium and PVC an option of hardened steel
cam locking points can be added to the standard multi point locking system
On sliding doors in aluminium and PVC a steel pin centre lock is availabe which renders the sliding leaves unmoveable when attacked or jemmied from any direction.
All Crystal windows persianas
come with security bolts in the final or terminal slat, with the option
of a lockable hardened steel drive in the terminal slat .
Crystal can offer a vast range of traditional rejas ( traditional spanish
style wrought iron security grills) which are galvanized dipped and often
painted for long life as standard.
An option in grills is extendable rejas which can open completely back and swing out and against house wall with fold away head and bottom guides when not required and lock with concealed drive when closed.
