Thinking about building a new home ? You will have to take into account the ever more stringent regulations on energy performance, aimed at building energy-efficient houses. Airtight construction is a key element in this.
Gain up to 3 S-points
Integrating a screen in a cavity wall is nothing new. Integrating roller-shutters while ensuring airtightness has become possible, too. But what about the insulation which you would normally find where the roller shutter box now comes ?
ShutterX® provides the solution. It is the first roller shutter that can be integrated in a cavity wall, completely airtight. The inner wall does not have to be pierced and, when rolled up, the roller shutter remains invisible from the outside. Better still, the insulation material which is taken away in order to build in the roller shutter is replaced by a composite profile behind the box. Not only does this profile take over the insulating value of the removed insulation, it even enhances it. Wilms’ innovations turn your windows in an acceptable thermal bridge and help you gain up to 3 S-points.

2. Composite profile - Replacing the insulation material in the cavity wall
In order to build the ShutterX® box into the cavity wall, part of the insulation material needs to be removed. WILMS has developed a composite profile to compensate for this.
3. Airtight - Equipped with an airtight film
WILMS always equips the composite profile with an airtight film at the top and the bottom of the window. This film is then perfectly finished against the outside of the inner wall.
4. Insulating construction plates - Avoid condensation
Forget poorly-insulating plywood and the problems it causes. WILMS’ solution takes away the risk of condensation.
5. Guide-rails - No visible screws
The ShutterX® guide-rails are nicely integrated in the wall and will not be noticed by anyone looking straight at the window. Also, we can paint the guide-rails in our own paint shop in any RAL colour you wish. That way, the guide-rails and the window are visually one. As the entire guide-rail is clicked together, you will not see any screws. The guide-rail consists of three parts, which facilitates installation. Central guide-rails are available, too, of course.
6. Fly screens - Keep insects out
There is a 15 mm space between the roller shutter and the window. This leaves enough space for a fly screen. Fly screen doors, plain, sliding or pleated, can be fitted, too, in front of the roller shutter.
7. Composite profile - Avoid humidity and cold window-sills
Cold and humidity always try to find their way into the house via the window-sills. WILMS has developed a special drainage profile which, in combination with the drainage film, keeps humidity at bay.
8. Window-sills - Aluminium or stone
For the window-sills, you can choose between aluminium and stone. You can order WILMS’ insulated aluminium window-sills in a RAL colour to your liking.
