Questions about sliding doors

Hello everyone,

I am currently dealing with sliding doors and have some questions.

Is it possible to install a sliding door to the terrace or balcony? How does it behave in terms of insulation and the tightness of such doors? It would be bad if heating costs increase after installation because there is a draft through the door.

So far, I have only found manufacturers (online) that offer many different sliding doors, but in the pictures, they are all inside the house. So I wonder if you can also buy sliding doors for the terrace from them? Or are those completely different doors?

Thanks for your answers! Max

Sure, there are also ones for terraces and balconies. Pay attention to an easy-to-use mechanism. With some doors, you have to coordinate 4 to 5 movements of the operating lever precisely for the thing to open - possibly. With good sliding doors, it slides open with one lever movement.

Oh, that doesn't work. They are insulated just as well as regular windows.
