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.
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.
Forget poorly-insulating plywood and the problems it causes. WILMS’ solution takes away the risk of condensation.
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.
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.
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.
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.
