Equip lift-and-slide doors with insect protection

We currently have simply not the best quality tape for the windows in our apartment but sufficient for us to "stick to the frame" with Velcro tape. It holds well for us and it's enough for the windows (including floor-to-ceiling ones). You can already see the net from 2 meters away and it is also not 100% taut but "flutters" a bit in the wind.

At the places where you want to go outside, we had a more expensive sliding element installed with a frame and a net that you can hardly see when it is not pollen season. We had to put "stickers" on it because you or visitors might walk through it too quickly. The wind comes through perfectly, and from 2 meters away you can't even see it. It is currently about 3 years old and still top quality. There are various manufacturers offering such sliding elements, each with different nets.

Of course, "integrated" would probably be more practical and somewhat nicer – for us personally – not worth the money.

There are also studios where you can look at these things. Maybe just drive there once. Measurements are currently not possible.

I would rather retrofit depending on the need. As soon as an integrated part causes problems, it will probably be inconvenient to replace it, etc. Have a look at WINDHAGER, we got theirs from Hornbach. We had these as exterior blinds that could be clamped, screwed, or glued into the jamb from outside. Individual parts could be reordered and I believe each piece costs about €80.-.
