Airtight built-in roller shutters help you save 43 euros per window per year

ShutterX is the first and only roller shutter to be built into the cavity wall in a completely airtight manner. It is the best choice when you want to combine high comfort and energy-saving in new constructions. Until recently, built-in roller shutters were problematic in new buildings as they are built into the cavity wall, which inevitably means that part of the insulation needs to be removed to incorporate the roller shutter box. This caused a thermal bridge. Wilms’ ShutterX built-in roller shutters solve this problem.

What's the gain from this built-in roller shutter?

Wilms has asked independent experts to calculate the savings from airtight built-in roller shutters versus traditional roller shutters. The outcome of their study is truly amazing. For an average window in an average detached house with four people, the energy saving is 43 euros per window per year. On the one hand, there is the thermal benefit (16,61 euros per window per year i.e. 38% of the savings), on the other hand, there is the saving from the airtightness (26,67 euros per window per year i.e. 62% of the total savings). To this, you need to add the higher comfort and the increased value of your house.

Keep the heat outside during Summer

Airtight roller shutters are useful in Summer, too, as they keep the heat outside. Erik Wilms, CEO of Wilms. ‘You must make sure that the heat does not enter your house. You can only achieve this by installing screens and/or roller shutters. From an energy performance perspective, keeping the heat outside is better than having to turn on the energy-guzzling air-conditioning system. In fact, you will not even need such a system.’
