Before you choose

Not all roller shutters and security grilles offer the same level of protection

There are many options on the market, but it is important to distinguish between two different ideas: one is to deter and the other is to better resist an attempted break-in.

Someone looking for an easy way in will usually focus on the point that offers the least resistance. A well-chosen roller shutter or security grille does more than protect the opening: it can also make that access point less vulnerable and less attractive than easier alternatives.

The key is choosing the right product for each situation. An upper-floor window, a terrace door, a ground-floor home, a commercial property and a second home that remains closed for long periods all have different requirements.

What do we consider before recommending a solution?

The aim is not to install the strongest option everywhere. It is to provide effective protection while preserving ease of use and the appearance of the façade.

Type of opening: window, balcony, door, terrace or commercial entrance.
Level of exposure: street-facing, internal courtyard, ground floor or detached property.
Day-to-day use: frequent opening, regular foot traffic or occasional closing.
Appearance: colour, design, visibility and discretion from outside.

Security roller shutters and grilles for homes, businesses and ground-floor properties

At Alustetic, we install made-to-measure security solutions in Olivella and nearby areas, adapting each shutter or grille to the type of opening, its level of exposure and the day-to-day use of the home or business premises.

Security for houses and detached homes in Olivella and nearby areas

Detached properties, residential developments and homes with external entrances, terraces or more exposed openings are common in Olivella. In these cases, the assessment needs to consider not only the product itself, but also the location of the entrance and how long the property may remain unoccupied.

Protection for commercial premises and frequently used entrances

In shops, offices and other business premises, security needs to combine strength, ease of use and a professional appearance. The best solution is therefore not always the same as for a home: daily foot traffic, shopfront visibility and the most practical type of closure all need to be considered.

Roller shutters for doors and windows

Types of aluminium roller shutters

Aluminium roller shutters for doors and windows can look very similar from the outside, yet their resistance varies significantly depending on the slat profile, material and locking system. It is therefore important to distinguish between a conventional roller shutter, an extruded aluminium shutter and a self-locking security shutter.

Aluminium roller shutter

This is the most common type of roller shutter. It provides privacy, solar protection and everyday convenience, but it should not be regarded as a security shutter in its own right.

Solar protectionPrivacyEveryday use
Extruded aluminium roller shutter for greater resistance

Extruded aluminium roller shutter

It is made from a more robust aluminium profile than a conventional roller shutter. This makes it a stronger option when the aim is to increase the protection of the opening.

Greater resistanceExtruded aluminiumMotorisation recommended
Self-locking security roller shutter for doors and windows

Self-locking aluminium roller shutter

This is the option most specifically designed with security in mind. Its system makes the shutter harder to lift from the outside, providing greater protection for exposed doors and windows.

Enhanced securitySelf-locking systemIdeal for ground floors

PVC roller shutters are also available, but we do not recommend them when durability and security are priorities: they are generally less resistant than aluminium and, in many cases, the price difference does not justify the compromise.

Security grilles for doors and windows

Types of security grilles

Security grilles for doors and windows can be fixed, hinged, collapsible or high-security systems such as Praesidium. The best choice depends on the level of protection required, how the opening is used and whether you need unobstructed access when the grille is open.

Made-to-measure fixed security grille

Fixed and hinged security grilles

A classic, robust solution widely used for windows, patios, ground-floor properties and entrances that require visible, long-lasting protection. They can be made in a range of designs and finishes.

Collapsible security grille

An accordion-style collapsible grille. It is practical when you need to open the entrance fully, keep the passage clear and secure it when required. It is commonly used on doors, commercial premises and frequently used entrances.

High-security Praesidium grille for homes

Praesidium security grille

One of the most secure and discreet options. Made from aluminium, it combines a minimalist design with an anti-drill cylinder, internal reinforcements and a system designed to protect while preserving a high level of outward visibility.

Choosing the right solution

Security shutter, fixed grille, hinged grille or collapsible grille?

The choice depends on three main factors: the level of security you need, ease of use and the visual impact you want to maintain on the façade.

When you want protection without significantly changing the appearance

Self-locking or extruded aluminium roller shutters can be a good choice when you want greater protection without fitting a visible grille to the façade. They are often used on large balcony doors, terrace entrances and ground-floor windows.

When you want a visible physical barrier

Fixed, hinged and collapsible grilles provide a clear, visible deterrent. They are particularly useful for street-accessible windows, internal courtyards, commercial premises and frequently used doors.

Common situations

The best security is the security that suits your home

The most expensive option is not always the right one. What matters is choosing the solution that best suits the entrance, its level of exposure and the ease of use you need.

01

Ground floor

Ground-floor openings are usually easier to reach and may therefore require greater protection. Self-locking shutters, hinged security grilles or Praesidium can be particularly suitable options.

02

Second home

If the property remains closed for long periods, it makes sense to prioritise robust, deterrent systems, particularly at the most exposed access points.

03

Terrace door

For these entrances, convenient day-to-day access also matters. Collapsible grilles, hinged grilles or self-locking shutters can all work well depending on the available space.

04

Commercial premises

The solution needs to combine security, easy opening and a well-kept appearance. It should protect the premises without making everyday use more difficult or unnecessarily compromising the façade.

Protection does not have to make your home feel like a fortress

A good security solution needs to do three things: protect, work comfortably in everyday use and suit the appearance of the property. If one of those three elements is missing, the result may become impractical over time.

We assess whether a roller shutter, a security grille or a combination of both is the best option.
We consider the installation method needed to achieve a secure, correct fixing.
We take colour, design and the visual impact from outside into account.
How we work

From “I want to protect this area” to a finished installation

Every opening has its own characteristics: walls may not be perfectly straight, existing shutter boxes may be old, or floors may slope. That is why accurate measurements and careful planning are essential before manufacture.

You tell us what you need

Window, door, ground-floor property, commercial premises or second home. The more we know about how the entrance is used and its particular characteristics, the better we can advise you.

02

We assess the options

We consider which option is the best fit and whether an alternative may better suit the intended use, appearance and level of protection you need.

03

We measure and prepare a quotation

We prepare a made-to-measure proposal based on the dimensions, finish, system and installation requirements.

04

We manufacture and install

We coordinate manufacture, finishes and installation to achieve a secure, clean and well-finished result.

Key point

A conventional roller shutter is not a security shutter. A visible grille is not always the most convenient option. And the solution offering the greatest protection does not necessarily have to create the greatest visual impact.

First, we assess the actual characteristics of the entrance.
Then we consider the most suitable product.
Finally, we make sure the finished result also looks right.
Frequently asked questions

Common questions before installing a roller shutter or security grille

Here we answer some of the questions we are most often asked, helping you understand the differences between systems and consider which solution may be the best fit in each case.

Does a conventional aluminium roller shutter provide security?

It provides privacy, solar protection and an initial physical barrier, but it should not be considered a security shutter. For greater resistance, an extruded aluminium or self-locking roller shutter is worth considering.

Which is better: a security grille or a security shutter?

It depends on the opening and how it is used. A self-locking roller shutter can increase protection while maintaining an integrated appearance, whereas a grille provides a visible physical barrier and a clear deterrent.

Which security grilles are suitable for a ground-floor property?

For ground-floor properties, fixed grilles, hinged grilles, collapsible grilles or Praesidium systems may all be considered, depending on the desired level of protection, the appearance of the façade and whether the passage needs to be opened or kept clear.

Can security grilles be made to measure?

Yes. Security grilles can be made to measure for windows, doors, large balcony doors, patios, commercial premises and other entrances.

Can security grilles be finished in different colours?

Yes. Depending on the model and material, they can be supplied in different colours and finishes to blend more naturally with the existing frames and façade.

Does a collapsible grille leave the passage clear?

Yes. That is one of its main advantages: it folds away to the side, leaving the opening clear when open. This makes it a practical option for doors and frequently used entrances.

Is Praesidium more discreet than a traditional security grille?

Yes. Its slimmer lines help preserve outward visibility and reduce visual impact compared with some traditional security grilles.

Do you install security roller shutters and grilles in Olivella and nearby areas?

Yes. We install security roller shutters and grilles in Olivella and nearby areas, tailoring each solution to the property, the premises and the characteristics of the entrance.

Would you like to protect a door, window or ground-floor property?

Tell us what you need to protect and we will help you assess whether a security shutter, fixed grille, hinged grille, collapsible grille or Praesidium system is the best fit, taking into account everyday use, appearance and the level of protection you are looking for.
