Thicker slats
They are made of extruded aluminium, stiffer and stronger than light foam-filled slats. They absorb impacts better and don't bend easily.

Real security
Security shutter or standard shutter: what's different?
A standard roller shutter controls light and temperature, but it can be forced from outside: with a lever or a hard pull, PVC slats or foam-filled aluminium slats bend or the shutter rises. A security shutter is designed to resist that attempt. These are the differences:
Lock against lifting
Once fully lowered, the slats jam against the guides and it is very hard to lift them from outside. The harder someone pulls, the tighter they lock.
Security guides and stoppers
The side guides have stoppers and parts that keep the shutter from shifting or coming out. A careful installation matters as much as the shutter itself.
Heavier, better with a motor
They weigh quite a lot more than a standard shutter, so we recommend fitting a motor: you raise and lower them with a switch or remote, effortlessly.
How it works
The self-locking, anti-lever system
In a self-locking shutter, the slats are joined by a connecting strip that acts as a hinge. When the shutter is closed and someone tries to lift it or force a lever in, the slats wedge against each other and against the guides, and the whole shutter locks.
The lock is mechanical: it doesn't depend on electricity or any digital system, so it works during a power cut too. No shutter is unbreakable, but these make entry much harder and make forcing one slow and noisy, which is usually what puts an intruder off.
- Locks by itself when lowered: there's no bolt to remember to activate.
- Designed to resist pulling, levering and attempts to lift it from outside.
- Lacquered finish that protects the aluminium from the weather.
- Compatible with a motor, wall switch and remote control.
Models
Types of security roller shutters we install
We recommend a model depending on the window, how much light you want to keep and the level of protection you need. These are the most common options:
Self-locking, solid slats
Closes the window completely and gives maximum protection and privacy. The most common choice for ground floors.
Self-locking, microperforated
The same locking system, with perforated slats that let light and air through when the shutter is down.
Reinforced extruded aluminium
Extruded slat that looks like a traditional shutter, with extra security reinforcements such as anti-lift straps.
Where does it make sense?
Where to install a security roller shutter
They are a good solution when you want to reinforce a window without changing the look of the façade. We mostly install them on:
- Ground floors, mezzanines and homes with street-level windows.
- Top-floor flats and terraces reachable from roofs or courtyards.
- Houses, villas and second homes that stand empty for long periods.
- Windows and balcony doors that are easy to reach from outside.
- Homes at risk of squatting or vandalism.
Our process
How we install your security shutter
-
Send us a photo
Of the window and the current shutter box. We'll point you to the right model and tell you whether the box or guides need replacing.
-
Visit and measuring
We measure each opening and check the state of the box, the guides and where the motor's power will come from.
-
Made-to-measure shutter
We prepare the shutter to the exact measurements, in the colour and slat type you've chosen.
-
Installation and test
We fit the shutter, the security stoppers and the motor, check that it locks and show you how to use it.
Convenience
Why do we recommend a motor?
A security shutter weighs more than a standard one, and raising and lowering it by hand every day is tiring and wears out the mechanism. With a motor you operate it with a switch or remote control, and it locks as soon as it reaches the bottom.
You can also set schedules so it raises and lowers by itself to simulate presence when you're away.
Before you start
The owners' association and the façade
Shutters are part of the façade. If you change the colour or type of shutter, it's wise to check with the owners' association first: many buildings ask for a uniform look.
Listed buildings may have extra conditions. We'll help you choose an option that suits the building.
Price
How much does a security roller shutter cost?
It costs more than a standard shutter, because it uses more material and a locking system. The exact price depends on each window, so we measure first and give you a fixed quote with no obligation. The main factors are:
- The number of windows and their measurements.
- The type of shutter: solid, microperforated or reinforced extruded.
- The colour and finish.
- Whether the box and guides can be reused or need replacing.
- The motor and type of control.

Common questions
Frequently asked questions about security roller shutters
How is a security shutter different from a standard one?
In the slats, which are thicker and made of extruded aluminium, and in the lock: once fully lowered, the shutter jams in its guides and it is very hard to lift from outside. A standard shutter can be bent or lifted relatively easily.
Does it need electricity to lock?
No. The lock is mechanical and always works, even during a power cut. Electricity is only needed if you fit a motor to raise and lower the shutter.
Do I still need bars as well as a security shutter?
It depends on the window and the risk. A closed security shutter greatly reinforces the window without changing the look of the façade. During the visit we'll advise you on whether it's worth combining it with another measure.
I've heard they're heavy. Is that a problem?
They weigh more than a standard shutter, which is why we recommend fitting a motor. That way you raise and lower them with a switch or remote, effortlessly and without straining the mechanism.
Can I see outside or let light in with the shutter down?
Yes, with the microperforated version, which has the same locking system and lets light and air through. With solid slats the window is completely closed.
Can I reuse my existing shutter box and guides?
It depends on their condition and whether they're compatible with the security shutter. We check during the measuring visit. If they don't fit, we'll suggest how to replace them.
Do you install all over Barcelona?
Yes. We work in every district of Barcelona and the metropolitan area. Message us on WhatsApp with a photo of the window and we'll tell you when we can come.
