In 2013, WILMS introduced a screen to be built into the cavity wall above the window. We had clearly already understood back then how important airtight building was going to become. We have continued developing our products ever since. Our ShutterX® technology is from now on also available for our ZipX®Zero.
Limit your energy demand, don’t restrict your view
Building a new home is subject to ever more stringent regulations on energy performance. However, highly insulated energy-efficient houses have some drawbacks, one of them being that these houses quickly overheat.
Wilms’ ZipX®Zero solves this problem and has other advantages, too. ZipX®Zero is an airtight built-in screen. It is fully integrated in the cavity wall and, thereby, completely hidden from view. As it is airtight, it has no adverse impact on your home’s energy performance. On the contrary, installing ZipX®Zero even improves the energy performance.
This unique combination is now possible due to several new techniques developed by Wilms. You can discover them hereafter.
2. Composite profile - Replacing the insulation material in the cavity wall
In order to build the ZipX®Zero 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. Carbon axis - Avoid roll marks on the screen fabric
Next to traditional steel axes, WILMS also offers carbon axes. This patented innovation with an improved fabric fastening prevents fabric slack and avoids horizontal roll-marks. Carbon axes are also very light, making them easy to handle and install. The same technique exists for aluminium axes which are suitable for shorter screens.
6. Guide rails - One whole with the window
As ZipX®Zero’s guide rails are integrated in the façade, they are invisible to anyone facing the window. Moreover, we coat or paint them in the same colour as the window profile. We have designed the guide rails in such a way as to allow putting fly screens. The guide rails come in three parts, which makes installing them easier still.
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.
