Security Shutters

Louvre Security Shutters

Aluminium louvre shutters that secure an opening without closing it off. Tilt the blades for light and privacy, and lock them for security.

A louvre security shutter is an aluminium shutter with blades that tilt, fitted across a window or doorway so the opening can be secured without being closed off. Tilt the blades to control how much light and privacy you get, and lock the shutter to turn it into a barrier, reinforced with 100mm hardened steel rods and held by a hidden tamper-proof lock.

The tilting blade is what makes a louvre shutter its own thing. The same shutter gives you an open window on a summer afternoon, privacy from the street in the evening, and a locked barrier overnight, all from one unit. The blades move independently of the lock, so you set light and air at whatever angle you want while the shutter stays secured.

The security is in the parts you cannot see. The blades are reinforced with 100mm hardened steel rods on both sides of the shutter. The lock is hidden and flush-fitting, with a double internal latch, and one key locks and unlocks the whole shutter. The hinges carry nylon inserts so they run quietly, and their pins are shouldered and tapered so they cannot be punched out.

The frame is deliberately slim, and so is the tilt mechanism. The tilt rod is hidden and the light line is reduced, so no bulky bars cross the opening. Everything is 6063-T6 grade aluminium, which is low maintenance and suited to the South African climate.

How a louvre shutter holds

  • Hidden tamper-proof lock

    A hidden, flush-fitting tamper-proof lock with a double internal latch. There is nothing on the face of the shutter to grip, lever, or attack, and one key locks and unlocks it.

  • Stainless steel securing bolts

    A stainless steel cylinder and bolt lock system adds stability and strength beyond the latch itself.

  • Reinforced blades

    The blades are reinforced with 100mm hardened steel rods on both sides, so they are not aluminium alone. That is what separates a security louvre from a decorative one.

  • Hinges that cannot be drifted out

    Nylon inserts keep the hinges running quietly, and the pins are shouldered and tapered so they cannot be removed or punched out.

  • Slimline frame, no bulky bars

    The frame is slim and unobtrusive while still secure, and the tilt rod is hidden with a light line reducer, so nothing heavy crosses the opening.

  • 6063-T6 grade aluminium

    The shutters are made from 6063-T6 grade aluminium, which is low maintenance, durable, and suited to the South African climate.

Hinged, bi-fold, or sliding

Three panel types, identical underneath. What differs is how the shutter opens and what the opening will take.

  • Hinged

    Designed to be kept closed, with the blades tilted for light control and privacy. Hinged panels are the most commonly specified for standard windows.

  • Bi-fold

    For a doorway, a run of windows, or a room divider. The panels fold away from the opening, which gives an unobstructed view and more opening space.

  • Sliding

    Used to cover an opening or divide an area for extra privacy. Sliding panels are easy to use and do not intrude into the room when you operate them.

Frequently asked questions

What is a louvre security shutter?
A louvre security shutter is an aluminium shutter with blades that tilt, fitted across a window or doorway so the opening can be secured without being closed off. Tilting the blades controls light and privacy, and locking the shutter turns it into a barrier reinforced with 100mm hardened steel rods.
Can I still get light and air through a locked shutter?
Yes, and that is the point of a louvre. The blades tilt independently of the lock, so the shutter can be locked shut and still let light and air through at whatever angle you set. Closing the blades fully gives you privacy instead.
Which panel type should I choose?
Hinged panels are the most commonly specified for standard windows and are designed to be kept closed with the blades tilted. Bi-fold panels suit a doorway, a run of windows, or a room divider, because they fold away and leave the opening clear. Sliding panels cover an opening or divide an area without intruding into the room when operated.
What stops the shutter being taken off its hinges?
The hinge pins are shouldered and tapered, so they cannot be removed or punched out. The hinges also carry nylon inserts, which keep them running silently.
What are the shutters made of?
Louvre security shutters are made from 6063-T6 grade aluminium, reinforced with 100mm hardened steel rods on both sides. The aluminium keeps the frame slim and the maintenance low, and the steel rods are what make the blades a barrier rather than a screen.
How long is the guarantee on louvre shutters?
Louvre security shutters carry a five-year guarantee, on all three panel types: hinged, bi-fold, and sliding.
Can I see one before I order?
Yes, and you should. Ask to see a sample before you commit to any purchase. Our consultants bring one to the free security assessment and will answer your security questions at the same time.
Can I pay louvre shutters off over time?
Yes. You can pay any DEFENDoor® order off over a term of up to 24 months through our finance partner, FeverTree.
