The right sun protection depends on your requirements, type of home and specific situation. Below is an overview of which type suits which needs:
Every home is different. Consider factors such as the orientation of your windows, how often you use the space and which style suits your façade.
Dark colours such as anthracite keep more heat out than lighter shades because they absorb the solar rays more effectively. They also offer better shading and fewer irritating reflections.
Lighter colours, such as white or beige, let more light and heat through, but create a fresher, lighter atmosphere.
Neutral shades, such as grey or taupe, offer a good balance between heat protection and light penetration.
The best choice depends on your preferences: If you want cooling and shade, choose darker colours; if you want more light and openness, go for lighter shades.
Outside sun protection repels heat before it reaches the glass and is therefore much more effective than inside sun protection. Solar rays that cannot hit the window cannot, in turn, heat up the indoor space. It thus stays around 5 to 7 °C cooler indoors, compared to a space without outside sun protection.
Outside sun protection can repel up to 85-90% of the sun’s heat, while inside sun protection often lets some of the heat in. Do you want maximum comfort in the summer without overheating or over-using your air conditioning system? Then outside sun protection is the best choice.
The price of sun protection depends on many factors. Below are the most important issues:
- Type of sun protection – Screens, pivot arm awnings, awnings, outside venetian blinds or veranda sunblinds. These all have a different price point.
- Dimensions – The larger the sun protection, the higher the price due to more materials being used, and the installation work.
- Controls – Manual systems are cheaper than electric or smart home solutions.
- Material and fabric quality – Durable fabrics, UV-resistant materials, and weather-proofing all impact on the price.
- Assembly and installation – Professional installation comes with extra costs, depending on complexity.
- Extra options – This could include LED lighting, wind or sun sensors and heating elements.
Harol sun protection comes with io controls as standard, allowing the device to be fully automated. Thanks to the connection with Somfy TaHoma, you can easily connect the system to your smart home and operate your sun protection remotely via your smartphone.
The io controls allow interactive operation: the system receives instructions and sends information back about the position of your screens or awning. You can then open or close your sun protection with one press of a button.
You can also set scenarios, e.g.
- open with the first rays of sun,
- automatically close when the sun goes down,
- or at fixed times when you are on holiday or go to sleep.
Lowering your sun protection will become an automatic reflex – for improved comfort, protection and energy efficiency.
Outside venetian blinds and screens are the most effective sun protection when it comes to heat, as they block sunlight before heat can penetrate the home via the windows. The indoor temperature thus stays noticeably lower, even on hot days.

Pergolas with a folding fabric roof can be expanded to include various accessories for extra comfort and convenience:
- Integrated LED lighting for a cosy atmosphere in the evenings
- Sun and wind sensors which automatically respond to the weather: the fabric lowers in bright sun and rolls up in high winds
- Heating elements for a pleasant temperature on fresher days
Specifically for models Phoenix Air, Phoenix Free, Nomo and Rialto:
You can expand these with a 230 V socket (available in Francia, Schuko or UK) or a USB combination port (type A + C) – handy for charging devices or connecting extra devices.
You thus turn your terrace into a smart, comfortable outdoor space, completely tailored to your lifestyle.
Depending on the model, there are various ways to close the sides of your pergola with a folding fabric roof. This not only increases the comfort, it also makes the outdoor space practical during changeable weather.
Thanks to these modular options, you can turn your terrace into a sheltered, cosy spot – completely tailored to your lifestyle and the location of your home.
The life expectancy of an awning is principally determined by the quality of the materials, exposure to sun, wind and rain, the frequency of use and the maintenance routine.
In practice, the fabric will show signs of wear and tear more quickly than the aluminium frame or the mechanism. Maintaining the fabric, cleaning it on a regular basis, and closing it during bad weather will keep it in a good condition for longer.
In short: good maintenance and smart use will ensure that your awning lasts for many years without any issues.
The price of an awning depends on a range of factors. These are the most significant issues:
- Type of awning – Folding arm awnings or canopies each have their own price range.
- Dimensions – The larger the awning, the higher the price due to the use of more material and the installation work.
- Controls – You can choose between manual controls, electric controls or integration with a smart home system. The price depends on the required convenience and technological level.
- Material and fabric quality – All fabrics are UV-resistant, but the price can vary depending on the material and type of fabric.
- Extra options – This includes integrated LED lighting, wind or sun sensors or heating elements.
The ultimate price depends on your personal requirements, the dimensions of the awning and the extra functions chosen.
Yes, awnings with io control offer advanced automatic operation. This technology enables interactive communication: the screen receives instructions and sends information back. You can use a central hub, such as Somfy TaHoma, to operate your awning easily using your smartphone, no matter where you are. You can also set personalised scenarios so that your screen automatically responds to situations such as bright sunlight or certain times.

In short:
An awning is a flexible solution for temporary shade, while a pergola is a permanent structure that also offers protection against rain and wind.
To keep your awning in great condition, it is important to clean it regularly:
- Box, arms and the drainage system must be cleaned at least twice a year with lukewarm water and neutral soap. Rinse thoroughly with tap water to remove any soap residues.
- The awning fabric is treated with a dirt-repellent product and is protected by the enclosed box. Nevertheless, you must clean it every now and then:
- Remove dry dirt by vacuuming, blowing, knocking or brushing.
- If there are any watery marks: moisten the fabric and gently rub with a clean cloth.
- Avoid soap or chemical products, unless absolutely necessary.
Regular maintenance will extend the life expectancy of your awning and ensure that the fabric continues to look good and function properly.
Yes, many modern awnings can be fitted with smart sensors which automatically respond to weather conditions. The most common are the wind sensor and the sun sensor.
How does it work?
- A wind sensor continuously measures the wind speed. When the wind increases, it sends a signal to the motor to automatically retract the awning.
- The sun sensor detects bright sunlight and lets the awning automatically roll out for extra comfort.
What are the benefits?
- Prevents damage during sudden gusts.
- Ensures automatic shade and comfort when the sun comes out.
- Extends the lifespan of your awning.
- Also works if you’re not home.
- Fully compatible with smart operation via io control.
A wind sensor is primarily interesting for windy regions or for larger awnings that are sensitive to the wind. For optimum ease, you can combine both sensors with a smart home system.
Awnings are resilient to moderate wind, but in the event of high gusts of 50 km/h or more, you are advised to retract the awning to prevent damage.
- Folding arm awnings or canopies are suitable for daily use, but are more sensitive to high winds.
- Pivot arm awnings offer slightly more stability as they are braced diagonally against the façade.
For added protection, a sun and wind sensor is recommended. This lets the awning automatically close during strong winds and extend during bright sunlight so that you always feel comfortable and secure.
No, an awning is not fully waterproof, but it is water-repellent. The fabric can cope with a light shower, but is not intended to protect you against heavy or long downpours.
NB: The awning may be rolled up wet, but make sure you dry it out afterwards to prevent the formation of mould and the fabric being stifled.
Do you want to keep out the sun as well as the rain? Then choose a pergola or awning with an extra water-resistant fabric.
Waterproof solutions within our outdoor living range include systems such as Opera or Brera
If you have a balcony, you are advised to choose a compact awning which takes up little space but still provides protection against the sun. These are the most suitable types:
- Folding arm awnings – Ideal for larger balconies. They provide shade without requiring poles or supports.
- Pivot arm awnings – A great choice for smaller balconies. They take up very little space and are great for providing shade.
- Lateral wind and sun screens – Handy if you have a windy balcony or would like more privacy.
The difference between the awnings primarily lies in the type of box and the extra options, such as LED lighting or a Vario valance.
Box types
The box protects the fabric and the mechanism when the awning is retracted. There are three types:
- Closed box: offers maximum protection against weather and dirt.
This type of box is used for models including BX260, BX270, Lux, Cadiz, Tucan and TC130
- Open box: the fabric remains visible, offering a light, open look.
This style suits the Praia model.
- Semi-open box: a combination of protection and openness.
This is used with the PR220.
Vario valance – extra protection when the sun is low
Anyone who needs shelter from the evening sun or protection from prying eyes needs the Vario valance: a roll-out flounce that is integrated into the extension pole. This is controlled electrically and can be rolled-out for up to 2 metres depending on the model.
The Vario valance is suitable for models Cadiz, Lux and Praia.
Depending on the model, there are various ways to integrate LED lighting in your awning. You are not only extending your summer evenings, but also opting for atmosphere, comfort and functionality.
LED lighting can be integrated:
- Into the box: for a gentle, direct light on your terrace
- In the arms: for a focused beam of light on seating areas or tables
- As indirect light: for a warm, diffuse glow without being blinded

Yes, zip screens have been specially designed to put up with high winds. Thanks to the integrated zip system, the fabric stays firmly fixed in the lateral guides and does not flap or come loose in high winds.
Zip screens remain stable in wind speeds of up to 80-100 km/h, depending on the model and the dimensions. This makes them ideal for windy areas, high floors or open corner situations.
With us, you can choose from various wind-proof zip screens, including: SC900-ZIP, SC1000-ZIP, Coolscreen 8, Coolscreen 8 Solar, Coolscreen 8 LED, Coolscreen 8 Plus
These models combine excellent sun-shading with high wind-resistance and are perfect for anyone looking for a combination of comfort, durability and user-friendliness.
To keep your veranda sunblinds in top condition, you are advised to clean them twice a year:
- Profiles and box: Clean at least twice a year with lukewarm water and a neutral soap, such as car shampoo. Always rinse well with clean tap water.
- Never use corrosive or aggressive products. Also avoid scratchy sponges or aggressive products that could damage the surface.
- Fabric: The fabric will stay clean for longer thanks to the enclosed box and the dirt-repellent finish. If necessary:
- Remove the dust from the fabric by vacuuming, blowing, knocking or brushing.
- If there are watery stains, moisten thoroughly and rub with a clean cloth.
- Use soap or detergents in exceptional cases only.
With regular cleaning, your veranda sunblind will not only stay clean, but you will also extend the life expectancy and effective functioning of the system.
Sun protection can help you to make substantial savings on energy consumption, both in the summer and the winter.
In the summer, the outside sun protection keeps most of the sun’s heat out so your home stays cooler and you do not need to ventilate or use your air conditioning as much. In the winter, well-placed sun protection helps to limit heat loss via windows and this has a positive impact on your heating costs.
How much you save depends on various factors:
- Orientation of your windows (sun protection on south or west-facing façades is more effective).
- Type and colour of the sun protection (darker fabrics absorb greater heat).
- Installation and operation (automatic systems respond quicker to changing weather).
- And the insulation level of your home and windows.
Want to get the most from your sun protection? Combine automatic controls, targeted installation and top-quality fabrics with a well-insulated home.
A veranda sunblind is the best choice for a skylight. These are installed above the glass and prevent the sun’s rays from coming in, thus preventing overheating. Veranda sunblinds connect perfectly to inclined glazing, such as skylights or rooflights. With the solar variant (runs on solar energy), you do not need an electric connection so it’s ideal for renovations or hard-to-reach roofs.
Yes, but the degree of wind-proofing varies per type of sun protection option. Not every system can cope with high winds.
- Screens – In general, these can cope with wind.
- Awnings – Less resilient during high winds. Most models fall under wind category 2 and this means that they should be folded away when wind speeds exceed 30-35 km/h.
- Pivot arm awnings – Thanks to their robust construction and fixed arms, these offer a high degree of wind resistance, even at very windy locations.
- Terrace sun protection with permanent structures – Pergolas with fabric or slats are usually more wind-resistant thanks to their anchoring.
For extra security, you can have wind and storm sensors installed. These will retract the sun protection automatically when the wind speed increases.
Yes, the fabric used for your veranda sunblind is treated with a dirt-repellent coating and is also effectively protected by the enclosed box construction. As a result, the fabric stays clean and better protected against weather influences such as dust, pollen and rain, for longer.
NB: veranda sunblinds are not designed to withstand prolonged rain showers like a pergola, but can cope with a light rain shower. Regular maintenance (dusting and gently cleaning) extends the life of the fabric.
Yes, some models, such as the VZ800-ZIP, can be fitted with integrated LED lighting in the box or the fabric supports. This creates a lovely atmosphere on your veranda, even as the evening draws in. The lighting is often dimmable and can be operated via a remote control or app.
So you can enjoy a comfortable and pleasant environment in the evening.
Yes, you can integrate a wind and sun sensor into the controls of your veranda sunblind.
- If the sun is bright, the fabric automatically lowers so that your veranda remains cool.
- If there are high winds, the system automatically retracts the fabric to prevent damage.
These sensors are great for combining with io control and home automation systems such as Somfy TaHoma, so you can set scenarios which are tailored to your daily routines.
Conclusion: There is a suitable screen for every type of home and preference, from discrete built-in to energy-efficient and atmospheric lighting.
Yes, screens improve privacy during the day. Thanks to the fabric’s special structure, you can see the outside from indoors, but the view for people outside is hindered.
Please note: In the evening, when indoor lights are switched on, the effect is reduced and people outside will be able to see in.
For complete privacy, in the evening too, black-out screens or roller shutters are a better choice.
You are advised not to roll up wet screens as this can lead to mould/mildew, stains and quicker deterioration of the fabric.
Is the screen wet due to the rain? Let it dry out fully before you roll it up. If you can’t do that immediately, roll it out again later to prevent any moisture being trapped.
To extend the life expectancy of the screen, and keep the fabric in good condition, it is important to keep it clean and dry.
Clean the screen’s box and profiles regularly with lukewarm water and a neutral soap, such as car shampoo. Rinse thoroughly with tap water to remove any soap residues.
Never use corrosive products, scratchy sponges or aggressive cleaning agents or you may damage the surface.
Thanks to the closed box, the fabric remains effectively protected from dirt, so you shouldn’t need to carry out any intensive maintenance.

Yes, screens can be installed on a corner window, as long as a suitable solution is chosen. The Coolscreen 7 has been specially designed for this application. Thanks to the cable guide without zip system, this model is ideal for corner windows and narrow profiles.
Depending on the situation, the screen can be fitted in front of the window, in the window opening or to the façade. With dimensions up to 3.5 metres wide or high and a maximum surface area of 9 m², this type of screen offers an efficient and elegant sun protection solution for corner windows.
Solar-powered screens are fitted with an integrated solar panel which provides the motor with power. As a result, no cabling or structural work is necessary; this makes the system ideal for existing homes or renovation projects.
This is how it works:
- The solar panel captures sunlight and turns it into electricity.
- A rechargeable battery stores the energy so that the system also works when there is little sunlight.
- The motor uses this energy to move the screen up and down using a remote control or an app.
An example of this type of solution is the Coolscreen 8 Solar. This model works entirely on green solar energy and has a powerful 2.2 Ah battery which has 30 days of autonomy, even in complete darkness. The system is suitable for screens up to 12 m² and is supplied as standard with a 7-year warranty on motor, battery and solar panel.
Solar-powered screens are energy-efficient, environmentally-friendly and easy to install, without cables, and offer maximum comfort.
The life expectancy of a pergola depends on multiple factors, including materials, the quality of the finish, exposure to weather conditions, and principally the maintenance.
With regular cleaning and careful use, the pergola will remain functional, attractive and reliable in the long term. Good maintenance helps to limit wear and tear, keep the components in good condition, and protect the construction against the impact of weather.
In short: the better your care for it, the longer you will be able to enjoy your covered outdoor space.
Yes, our pergolas come with an io control as standard; this can be connected to your home automation system via Somfy TaHoma. You can thus control and monitor the position of your pergola remotely, using your smartphone.
With a simple instruction, you can immediately adjust the pergola’s position. Thanks to the io control, you can also fully automate the system: let your pergola open with the first rays of sun and automatically close when the sun goes down or at a time of your choosing. You can thus combine comfort, efficiency and convenience in a smart solution.
Regular cleaning and maintenance will extend the life expectancy of your pergola and keep it in top condition. Depending on the type of pergola, there are various focus areas:
- Pergola with roll-up or folding fabric – Clean the fabric with lukewarm water and a soft brush to prevent a build-up of dirt and the formation of mould. Do not use aggressive cleaning products.
- Pergola with slats – Rinse the slats with water and check the run-off regularly for blockages.
The price of a pergola depends on various factors:
- Type of pergola – Roll-up fabrics, folding fabrics, slatted-roof pergolas – they all vary in price.
- Dimensions – The larger the pergola, the higher the price due to the use of more material and the installation work.
- Extra options – Lighting, heating, sliding walls – these can all elevate the price.
- Installation costs – Professional installation and any adjustments to the subsurface or façade will impact on the cost.
The ultimate price depends on what you want, the dimensions and any additional options.
Whether you need a permit for a pergola depends on the laws in your country and municipality. In many cases, a pergola can be installed without a permit, if it fulfils certain conditions, such as a limited surface area, maximum height and adequate distance to the plot boundaries.
NB: The rules vary widely between countries and even regions. Always find out more from your local government or architect, or consult the environmental desk in your region. Then, you can be sure that your pergola fulfils the prevailing regulations.
A roll-up and a folding fabric roof are both flexible solutions for pergolas, but vary in terms of operation, look and functionality.

No matter which option you choose, both fabric roofs offer a flexible way to protect your terrace and create an atmosphere. The choice depends on your preferences for appearance, light control and user comfort. You can thus adapt your pergola to your lifestyle and outdoor requirements.
Pergolas are generally built using a modular system and can be expanded with accessories for extra comfort and convenience.
This could include:
- Integrated LED lighting for a pleasant atmosphere in the evenings.
- Sun and wind sensors which automatically respond to the weather; the fabric lowers in bright sun and rolls up in high winds.
- Heating elements which make the space under the pergola more pleasant during fresh days or evenings.
These accessories make your pergola smarter, more comfortable and more durable by responding to seasonal changes and extending your living space.
The Vario valance (on solar energy) is a vertical awning which is installed at the front of the pergola and is only available with the Versuz Linea.
With a maximum height of 1.5 metres, it offers optimum protection against low sun in the early morning or late afternoon, without completely blocking your view.
Ideal if you are looking for extra shade, for example for a south or west-facing terrace.
For pergolas with roll-up fabric, a side closure is only possible on the AIR. This model offers multiple options to protect the sides of your canopy from sun, wind and rain:
- Integrated screens: carefully concealed in the structure and ideal for extra shelter and privacy.
- Triangular fabric enclosure: closes the opening between fabric and lateral guide and increases wind resistance.
- Wooden sliding walls: turn your pergola into a cosy outdoor space for every season – Wooden walls provide privacy and ambiance.
With these accessories, your terrace remains comfortable and accessible in any weather, exclusively with the pergola Air.
The foundations must be robust enough to bear the weight of the construction and prevent subsidence. The right choice depends on the size, the material and the surface on which you are building.
Possible foundations:
- Concrete tiles or clinkers – Suitable for light pergolas, as long as the surface has been levelled and compacted.
- Concrete plinths – Ideal for medium-heavy to heavy constructions, are dug in and filled with concrete.
- Full concrete foundation – Needed for large or free-standing models, offers maximum stability.
- Screw or point foundation – Quick, robust solution for loose or soft ground.
Which should you choose?
- Small pergolas → Strong tiles or clinkers are fine.
- Larger or free-standing models → Concrete plinths or a concrete slab are recommended.
A sturdy foundation guarantees stability and will extend the life expectancy of your pergola.
A pergola with slats offers a combination of flexibility, comfort and protection.
- Light control – Slats can tilt to precisely regulate the shade and light penetration.
- Ventilation – Open slats let air circulate and help prevent overheating.
- Protection – Closed slats offer protection against sun, rain and wind.
- Automation – Our models can be adjusted electrically, often using a remote control or via an app.
- Modern look – Sleek and stylish design which suits both modern and classic homes.
Ideal for anyone who wants maximum control over light, air and comfort on the terrace.
Most pergolas are resilient to normal weather conditions, but in the event of a storm or snowfall, there are a few important precautionary measures to prevent damage.
- With slatted-roof pergolas, you are advised to open the slats when snow is falling so that the snow can fall between the slats and not build up on top of the roof. If the roof is closed, the weight of the snow may lead to damage.
- Folding and roll-up fabrics must always be retracted when there is snow or high winds. These systems are not designed to cope with long-term loading or high gusts of wind.
Yes, but the degree of waterproofing depends on the type of pergola.
Waterproof level per type of pergola:
- Pergola with slats – Waterproof when the slats are closed, as long as there is a good drainage system.
- Pergola with folding or roll-up fabric – Water-repellent, but not 100% waterproof; less suitable for long periods of rainfall.
Would you like a fully waterproof pergola? Then opt for a slatted-roof pergola with integrated water drainage.
All pergolas with slats can be expanded with accessories which make your outdoor space even more comfortable, smart and user-friendly:
- Integrated LED lighting in the slats or structure, for atmosphere and illumination in the evening
- Heating elements which make the terrace pleasant in the cooler seasons
- Sun and wind sensors which make automatic adjustments based on the weather
With these accessories, you can enjoy a flexible, well-equipped outdoor space, which is fully tailored to your comfort needs, all year round.
All pergolas with slats can be fitted with side closures for extra protection against sun, wind and rain. You can choose from:
- Screens: combat the wind, sun and offer greater privacy, and are seamlessly integrated in the structure
- Wooden sliding walls: offer extra privacy and a warm, natural look
Thanks to these closures, you create a sheltered and atmospheric outdoor space which you can use all year round, even during changeable weather.
Yes, roller shutters can reduce noise pollution, particularly models with an insulating box and/or slats. They form an extra barrier against noise, such as traffic and wind.
How can you improve sound insulation?
- Choose the right material – Aluminium roller shutters with foam filling offer better insulation than PVC.
- Opt for thicker slats – Thicker slats absorb more noise.
- Make sure that your roller shutters are completely closed – A properly closed roller shutter can prevent noise coming in through small openings.
Tip: Sound-insulating roller shutters help keep out low-frequency noise such as traffic noise or noise from the wind, but do not offer 100% sound insulation.
With roller shutters, you can save up to 10% on heating and cooling costs, depending on the insulation and usage.
- In the winter, insulated roller shutters limit heat loss by 25-30%, meaning you need less energy to heat your home.
- In the summer, they keep up to 90% of the solar heat outside, making you less dependent on air conditioning or ventilation.
The savings depend on the material, the degree of insulation and the use of the roller shutters. The colour also plays a role: white roller shutters reflect more sunlight and are more efficient at keeping the summer heat outside. Black roller shutters, by contrast, absorb more heat and can offer a slight advantage in winter because they take up more heat on the outside. Smart roller shutters with automated controls can further reinforce this effect.
Tip: Combine roller shutters with home insulation and well-insulated windows for maximum energy savings.
Double glazing and roller shutters both contribute towards insulation but in different ways:
- Double glazing prevents heat loss and principally helps with heat insulation. High-performance glass (HR++) or triple glazing (HR+++) is even more effective.
- Roller shutters form an extra insulation layer, reducing heat loss in the winter by 25-30%, leading to a lower energy requirement to heat your home. In the summer, they keep up to 90% of the solar heat outside, making you less dependent on air conditioning or ventilation. Closed roller shutters can save up to 30% energy in terms of heating and cooling.
What is the best choice?
- For retaining heat in your home, double or triple glazing is essential.
- For maximum insulation, a combination of double glazing and roller shutters is the best option.
Do you want to retain the winter heat indoors and keep your house cool in the summer? Then the combination of both offers the highest level of insulation.
The cost of roller shutters varies according to various factors. These are the most significant issues:
- Type of roller shutter – Built-in roller shutters are more expensive than surface-mounted roller shutters.
- Controls – Electric and smart home roller shutters cost more than manual ones.
- Material – Aluminium is more sustainable and better at insulating than PVC, but it is also more expensive.
- Acoustic and thermal insulation – Roller shutters with extra insulation against noise and temperature fluctuations cost more.
- Burglary security – Reinforced slats and extra security options increase the price.
- Dimensions – The larger the roller shutter, the higher the price.
- Extra options – Sensors, solar-drives, or personalised finishes add cost.
- Installation – Professional installation corresponds with additional costs.

Roller shutters must be cleaned at least twice per year to prevent a build-up of dirt and wear and tear. Follow this step-by-step plan to ensure thorough cleaning.
Step 1: Let the shutter roll all the way down so that you can access all areas.
Step 2: Use a soft sponge or microfibre cleaning cloth with lukewarm water and a mild cleaning agent. Avoid aggressive cleaning products which could damage materials.
Step 3: Remove dust and dirt from the side runners with a dry cloth or soft brush to prevent a build-up.
Step 4: Let the roller shutter dry completely before rolling it up to prevent damp and damage to the various parts.
Step 5: If necessary, lubricate the moving parts with a suitable lubricant to prevent wear and tear and ensure the shutters run smoothly.
Tip: Regular cleaning and maintenance will extend the life expectancy of your roller shutters and prevent expensive repairs.
There are various types of roller shutters, each with their own characteristics and applications. Below is an overview of the most common types:
| Roller shutter type |
Features |

Roller shutters have an average life expectancy of 20 to 25 years, depending on the materials, usage and maintenance. With good maintenance, they may last even longer.
Factors which affect life expectancy:
- Material – Aluminium and steel last longer than PVC.
- Controls – Manual roller shutters deteriorate quicker than electric variants.
- Maintenance – Regular cleaning and lubrication extend life expectancy.
- Extreme weather conditions – Roller shutters should be rolled up during high winds or storms as this prevents damage to slats and guide rails.
Tip: Want to keep your roller shutters in great condition for as long as possible? Make sure you service them twice a year.
Roller shutters can be automated in various ways. With an electric motor and smart controls, you can open and close them automatically using:
- Timed schedules – Set the times when you would like the shutters to go up and come down.
- Solar sensor – A solar sensor allows the roller shutters to automatically respond when the sun shines, ensuring you are always comfortable and protected.
- Smart home integration – Operate them via Somfy TaHoma with an app.
- Can be connected to home automation via Somfy Tahoma so you can operate and monitor the position of your roller shutters remotely.
- Roll down your shutters with just one instruction on your smartphone.
- Lowering your roller shutters is a piece of cake. Your home is better protected in an instant.
- You can set up scenarios before leaving home, at bedtime, or during holidays.
Tip: Want to automate your roller shutters without cabling? Consider solar roller shutters, which work on solar energy and are operated wirelessly.
Yes, surface-mounted roller shutters can be fitted on any type of window, both in new-builds and renovations. Because they are fitted to the outside wall or to the window itself, no structural modifications to the window or wall are required.
Where are surface-mounted roller shutters used?
- Small and large windows
- Tilt and turn windows
- Sliding windows and doors
- Existing homes without space for built-in roller shutters
Solar roller shutters work entirely on solar energy and are a sustainable solution for automatic control. They do not need any cabling and are easy to install.
Benefits of solar roller shutters
- Energy-efficient – Work on solar power, no electrical connections required.
- Easy installation – No structural work or extra cabling required.
- Suitable for existing homes – Ideal as a replacement for manual or electric roller shutters.
Roller shutters can cope with windy conditions, but in the event of very high winds or storms, it is important to protect them and prevent damage.
- In high winds – Close the roller shutters completely to the bottom to prevent flapping and damage.
- In storms – Roll the shutters completely up to prevent damage.
- Avoid half-open roller shutters, because the wind can then take hold easily.
- Check the lateral guides regularly for wear and tear or loose parts.
Roller shutters and screens both provide sun protection and energy savings, but vary in terms of shading, insulation and security.
Most important differences
- Shading – Roller shutters block maximum light, screens let some light through.
- Heat-proofing – Both screens and roller shutters offer excellent protection against solar heat. Screens filter sunlight and keep a great deal of heat outside, while retaining the view outdoors. Roller shutters perform slightly better in both summer and winter because they completely cover the window and offer additional insulation.
- Insulation – Roller shutters reduce heat loss in the winter better than screens.
- Privacy – Screens retain the view outdoors during the day, roller shutters close everything down completely
- Security – Roller shutters are more robust and help to prevent burglaries, screens do not offer any extra security.
Which should you choose?
- For shading, insulation and security → Roller shutters.
- For sun protection with light permeability → Screens.
The VR150 is fitted with an ultra-quiet tubular motor and a ‘soft-start & stop’ function, allowing the roller shutter to open and close almost silently. This technology eliminates the noise of the slats which press against one another and ensures a smooth operation. Furthermore, the VR150 Silensio offers a 40% longer lifespan and superior obstacle detection which, in turn, supports both comfort and durability.
The VR150 Blackout has been specially designed for maximum shading, making it ideal for bedrooms. Thanks to innovative features such as a sealing strip across the full box width, a black insert in the guide profile, light-repellent brushes in the lateral guides and a bottom lath with a light-absorbing brush, all the light is effectively blocked. This ensures great quality sleep, even during the day, and is perfect for light-sensitive people and shift workers.
The most important difference between the VR150 and the VR200 lies in their application and construction. The VR150 is suitable for standard windows and offers excellent sound and thermal insulation. The VR200 has been specially designed for very large windows and doors, with a more robust construction and extra sturdy slats (ALU55) which provide increased security and stability. Both models can be adapted to the style of your home and there are various box shapes and colours.
Yes, that is possible thanks to an integrated screen. This allows you to leave the roller shutter partially open to let in the fresh air, while insects are kept at bay. So, on hot days or evenings, you can safely and comfortably ventilate your home without mosquitoes or other insects coming in.
Yes, some building work will be necessary for built-in roller shutters because the shutter box will have to be integrated into the façade. This makes them suitable for new-build projects or major renovations, when walls or windows are to be renewed. With an existing house, extra work is often needed to make space for the shutter box.
Tip: When working on a new-build construction or renovation, consider roller shutters with extra insulation, so that they support energy efficiency and a lower energy bill.
The choice of built-in roller shutters, surface-mounted roller shutters and built-on shutters depends on the type of home and the desired installation method. Below is a list of the most important differences:
| Roller shutter type |
Features |
Benefits |
Disadvantages |
| Built-in roller shutters |
Shutter box concealed in façade |
Sleek finish, good insulation |
Only suitable for new-build projects or major renovations |
| Built-on roller shutters |
Pre-fitted on window frame, installed with the window |
Good insulation, ideal for renovations and new-builds |
Box remains visible on the inside |
| Surface-mounted roller shutters |
Shutter box on the outside of the window or façade, no structural works required |
Simple installation, ideal for existing homes and renovations. |
Less integrated appearance, can impact upon insulation level |
Which roller shutters should you choose?
- For new-build projects or major renovations → Built-in roller shutters for a sleek finish and extra insulation.
- For renovations without major renovations → Built-on roller shutters as a balance between insulation and installation ease.
- For existing homes without structural work → Surface-mounted roller shutters, the most flexible option without any construction work.
The secret of the OB920 built-on roller shutter lies in the innovative insulation of the shutter box, which provides superior thermal and acoustic insulation for your home. Thanks to this advanced insulation technology, both heat loss and noise pollution are significantly reduced, contributing to a more comfortable and energy-efficient indoor environment. This makes the OB920 ideally suited for low-energy houses, major renovations and new construction projects.
Yes, that is possible. Built-on roller shutters such as the OB600, OB700 and OB920 can be partially opened to let fresh air in while the window remains largely covered. For extra comfort, you can choose an integrated screen, which allows you to ventilate your home without insects getting in.
Roller shutters and air conditioning affect the temperature in the home but work in different ways:
- Roller shutters block sunlight before it reaches the window, preventing the indoor temperature from rising and saving energy.
- Air conditioning actively cools the indoor air but consumes a great deal of electricity and increases energy bills.
What is the best option?
- For energy-efficient heat-proofing, roller shutters are the best choice.
- For direct cooling, air conditioning is effective but is less sustainable.
- The combination of both prevents overheating and reduces energy consumption by the air conditioning system.
Roller shutters offer a barrier to burglars, particularly models with reinforced slats and extra locking. They make it harder for burglars to force windows and doors, but do not offer complete security.
How do roller shutters make your home safer?
- Reinforced slats – Extra robust materials increase resistance to burglars.
- Security guide rails – Prevent the roller shutter being easily lifted out of the guides.
- Lift security system – Prevents the roller shutters being pushed upwards.
- Security bottom lath – Prevents anyone getting a grip on the bottom lath to break the roller shutters open.
For large windows or extensive glazing, you need sun protection which offers effective cover, is wind-proof and will stay in place. Not every system is suitable. These are the best solutions:
| Type of sun protection |
Why suitable for large windows? |
| Screens |
Tightly tensioned fabric which keeps heat out without blocking the view. Wind-proof and ideal for large windows. |
| Outside venetian blinds |
Tilting slats which can be used to regulate light penetration and also keep sunlight off the glass. Modern and efficient for broad areas of glazing. |
| Veranda sunblinds |
Specifically developed for skylights, verandas and rooflights. Reduce overheating with large, horizontal glazed areas. |
Conclusion:
For vertical windows, screens and outside venetian blinds are the most suitable option. For roof glazing or sliding glass elements, you should choose veranda sunblinds.
Outside venetian blinds should be maintained like windows: regular cleaning with lukewarm water and a neutral soap, such as car shampoo. Rinse thoroughly with tap water to remove any soap residues.
Never use corrosive or aggressive products and avoid scratchy sponges or other aggressive products, as these could damage the slats.
Thanks to the protective box, the slats are well protected against dirt when they are raised; this makes cleaning easier and extends the life expectancy.
Outside venetian blinds and screens both offer sun protection but vary in functionality and control over light and privacy.

Choice? Outside venetian blinds offer more control over light and privacy, while screens are more wind-resistant and easier to install.
Outside venetian blinds have been designed to cope with wind, particularly when they are lowered. Models such as the BZ1000 and BZ700 have been tested to wind category 3 (EN 13659), which corresponds with wind speeds of up to 80 km/h.
With wider installations, extra tension cables or attachments can be added to provide greater stability. This makes outside venetian blinds suitable for windy façades or higher floors.
Yes, outside venetian blinds can be fitted with wind and sun sensors for extra comfort and security.
- The sun sensor lets the blinds automatically lower in bright sunlight so that your home stays cooler without manual operation.
- The wind sensor ensures that the venetian blinds automatically rise during high wind to prevent damage.
These sensors work together with the io control system and can be integrated in a smart home environment, such as via Somfy TaHoma. As a result, you can also set your scenarios based on time or weather conditions.
