The security doors page gives general advice on how to secure your doors using the various roller shutter and grill systems and points to suppliers of security doors.

introduction to security doors
There are roller shutters doors for garages and sheds, there are grilled and framed doors fitted with security screens
and
there are special heavy duty glass security systems all to fit your security doors.
Roller shutter doors consist essentially of a curtain of interlocking slats which form a continuous
hinge along their
entire length. This construction permits the curtain to roll up or down as it is raised or lowered onto a revolving
spring loaded barrel which is mounted onto steel support brackets. A bottom rail fitted to the curtain of the security doors strengthens
the curtain and allows for the fitment of handles and locking devices. The curtain is also prevented from moving
side-ways by side channels or guides. The entire assembly is either bolted or welded to the structure and the rolling
mechanism is enclosed in a canopy hood.
some general security advice on doors
front doors
External doors should be of solid construction - at least 44 mm thick and hinges should be strong.
Most newly built properties are fitted with a simple rim lock, also known as a 'night latch'. For satisfactory security
levels a five-lever mortice deadlock should be installed.
If the door is hollow, or too thin for a mortice lock, a quality rim deadlock should be installed using long, strong
screws.
The security doors deadlock is important because it means that the door is much more difficult to force open. Also once the door has
been locked with the key, the burglar won't be able to put his hand through the letter box or through a panel and open
the door from the outside. If he is in the house, he also won't be able to open the door which means he cannot use it to
get out of the house with bulky items.
Security doors deadlocks are also important in relation to doors with glazed panels which are inherently less secure than solid doors.
You should consider replacing ordinary or toughened glass panels with laminated glass as this offers greater
resistance.
Internal rack bolts at the top and bottom of the security doors provide additional security.
It is also important to consider fire safety issues when looking at security precautions. You may feel that you don't
wish to use the mortice lock when you are in, as this will make it more difficult to get out of the house in the event
of a fire. If this is the case, bolts at the top and bottom of the door are particularly useful.
It should be noted that it is generally not possible to add security doors features to UPVC/PVCU front doors after they have
been installed, but they would usually incorporate appropriate locking mechanisms.
Before replacing any locks, see what your insurance policy states that you should have.
for additional security, fit a spy hole and door chain.

back security doors
The back door should also be fitted with a five-lever mortice deadlock and have bolts at top and bottom.
Glass panels should be laminated and fitted from the inside to prevent putty or beading being removed.
patio security doors
Patio doors are a common means of entry and so, unless doors are fitted with a multi-locking system, it is a good idea to fit extra locks and an anti-lift device.
Steel entry security doors offer more than lasting beauty to your home. They provide the benefits of high value security of a steel door. All this plus your refinish doors offer low maintenance and eliminates the warping, chipping and peeling of wood and painted doors.
