Are all built-in roller shutters airtight?
Not all built-in roller shutters are airtight, but Wilms' ShutterX® roller shutters are, which makes them ideal for new builds. Traditional built-in roller shutters still allow heat to escape, which means you lose energy. Your Wilms dealer will be happy to go through the options with you.
What is the difference compared with other types of roller shutters?
Built-in roller shutters are ideal for new builds or major renovations because the box is integrated into the cavity wall. If you are doing little or no renovation work, it is better to choose surface mounted roller shutters or built-on roller shutters. Our craftsmen install surface mounted roller shutters on the facade without any demolition work and mount built-on roller shutters on top of the window profile when you replace your windows. Contact your Wilms dealer to discuss all options in detail.
How much energy can I save with airtight built-in roller shutters?
In new builds, you can improve your S level – an indicator of how energy-efficient your building envelope is – by up to 3 points. Put simply: your home needs less energy to stay at the right temperature, which has an immediate impact on energy performance, living costs and comfort.
Can I have my existing built-in roller shutters replaced?
Our craftsmen can replace your built-in roller shutter with a new Wilms model. Already have built-in roller shutters and want to switch to the airtight ShutterX® system? Your Wilms dealer will be happy to look at the possibilities with you.
What is the maximum width of built-in roller shutters?
Today, we can make built-in roller shutters quite wide, even up to 3 metres by 3 metres. For wider openings or special situations, your Wilms dealer will always look for the best solution together with you, for example a roller gate.
The box in which the roller shutter rolls up is completely concealed in the cavity wall. The box height is 26 centimetres and the width is 20 centimetres.
