Tailor-made solutions for modernisation Roller shutters and fabric screens for a range of requirements Many systems can also be retrofitted to existing windows A wide range of colours, designs and user-friendly control options
Anyone wishing to retrofit their windows with sun protection can choose from a range of different systems. The right solution depends on individual requirements. Whilst some systems are primarily designed for blackout and privacy, others allow for precise light channeling or combine effective heat protection with an unobstructed view of the outside. Among the most popular retrofit solutions are roller shutters and fabric screens. Both options protect against solar radiation and help to reduce the build-up of heat inside rooms. However, they differ in terms of their functions, design options and range of application.
Roller shutters – sun, privacy and thermal protection all in one system Roller shutters are among the most versatile sun protection solutions for windows. Not only do they offer effective protection from solar radiation, but they also provide privacy and almost complete blackout. Furthermore, they can help to reduce heat loss through the windows during the colder months and provide additional burglary resistance.Thanks to modern front-mounted systems, roller shutters can often be retrofitted and are therefore ideal for modernising existing buildings.Advantages of roller shutters: Effective protection from the sun and heat Greater visual screening, more privacy and security Option to completely darken living rooms and bedrooms Additional support for heat insulation Ideal for retrofitting
Textile screens – heat protection whilst still allowing a clear view of the outside Textile screens are made from high-quality fabric. As their installation is carried out on the outside of the window, a large proportion of the solar radiation is blocked before it reaches the window. This reduces heat build-up inside the room whilst allowing daylight to enter.Depending on the fabric used, textile screens also provide effective privacy protection from the outside without completely obstructing the view outwards. Thanks to their delicate design, they are particularly suitable for large window areas and modern façade designs.Advantages of textile screens: Effective heat protection for living spaces Panel and privacy protection whilst still allowing a view outwards Making the most of natural light despite sun protection A sleek and modern look Ideal for large windows

Yes, roller shutters and fabric screens can usually be retrofitted to existing windows. This is often done using a front-mounted system, which is fitted to the outside of the window and is therefore particularly suitable for modernisation projects. The solution best suited to your building depends on the structural conditions and your individual requirements.
The cost of retrofitting an external sun protection system depends on various factors. These include, amongst other things, the chosen sun protection solution, the size of the window, the number of units, and the desired features and control system. For an accurate cost estimate, we recommend consulting a heroal specialist partner. Find a specialist partner >
Which solution is right for you depends on your requirements. Roller shutters offer versatile protection from the sun and prying eyes, and can also help to completely block out light and enhance burglary resistance. Fabric screens combine effective sun protection with the use of natural light, as well as a delicate façade design. Nowadays, a combination of both solutions is often used – for example, fabric screens in living areas where natural light and views need to be preserved, and roller shutters in bedrooms where complete blackout is particularly important. Our specialist partners will help you find the right solution for your home. Find a specialist partner >
