windows with integrated blinds to filter the sun’s rays in summer


Every day, Anicet Mbida makes us discover an innovation that could well change the way we consume. This Friday, he is interested in a French technology developed by the startup Immoblade, windows with integrated blinds that block the sun in summer and let it through the winter.

The innovation of the day could avoid transforming the interiors into a sauna with the arrival of fine weather. These are windows with integrated blinds that block the sun in summer and let it through the winter.

We are talking about a window, not the entire window! In addition, this blind integrated into the glass works completely passively. There is nothing mechanical or electrical to lower, raise or unroll. It is also not an electro-chrome glass, those that darken with an electric current. Again, there is nothing to plug in. We simply install the glass. We forget it. And it will automatically block the sun’s rays but only in summer.

How it is possible ?

On the surface of the glass, we have drawn a pattern made up of small oblique lines, more or less wide, which will play the role of a blind. The shape of this pattern has been calculated to be able to follow the path of the sun all year round, and to hide a maximum of rays in summer when the sun is higher. Conversely, it will let them pass in winter when the sun is lower. All this while playing on the angle and the thickness of the lines.

It also means that each window will have to have a different pattern, calculated according to its orientation and its GPS position. But we thus manage to block 95% of the sun in the summer in a completely passive way.

This is a French technology developed by the startup Immoblade.

Is it still a prototype or are there already buildings equipped?

It begins. They have just fitted out a La Poste building in Rennes and the new offices of the management center of the Ariège departmental council in Foix.

So if you pass by and see some funny patterns on the windows. This is not to look pretty. They help limit the need for air conditioning in summer, and heating in winter.
