Built-on roller shutters are always installed together with your windows and doors, making them particularly suitable for new homes or if you want to replace the windows of your existing home. They are an excellent alternative to the traditional built-in roller shutters of the past which were suspended in a space above the window.

The big difference with roller shutters of the past is that the roller shutter boxes are pre-insulated and perfectly fit with the window profile. This makes them highly energy-efficient and, obviously, also easier to maintain. You no longer need to call on a carpenter. Indeed, the boxes are entirely finished and fit in with your home interior.

Combine your built-on roller shutters with a ventilation system

Insulation and ventilation are the key words in construction today, be it for new buildings or for renovations. Rolvent®, an advanced innovation of our built-on box, brings the best of both worlds. Our built-on box with integrated ventilation is unique in its kind. Indeed, it is the only product on the market which ensures a permanent air flow, even when the roller shutter is closed.

The required ventilation is calculated based on the flow-rate of the space. Once you have achieved the required ventilation flow rate, you can continue with ordinary built-on boxes i.e. without a ventilation grid. You can therefore combine boxes with and boxes without ventilation.

Customised finishing

Depending on the installation, you can choose to have the roller shutter box visible indoors only. This does require having sufficient space above the windows, e.g. when you are replacing your old built-in roller shutters. In case you do not have sufficient space, you can opt for lower windows, with the built-on roller shutter box visible outside.

The front plate is then, obviously, finished in a colour to your liking. The same goes for the guide-rails, the bottom lath and the other parts of the box. WILMS’s built-on roller shutters have either PVC or aluminium slats, both types available in a wide range of colours.

With a ventilation system, you may experience noise nuisance coming from outdoors. WILMS solves this, too, with a sound-insulating version of the box. The additional sound-insulation is fully integrated in the box, making it invisible, and does not change the size of the box.
