I am a bit conflicted... we have a sliding lift door and out of all the door and window elements, it feels like the most fragile. It has the worst U-value, has squeaked before, and always gives me a headache when the children mess around with it. On the other hand, of course it's nice that it is not in the way - but in my opinion that is often just a crutch when you have messed up the planning.
The romance and the idea of the door to the world always being open – especially in summer – also did not really happen, since it was always significantly warmer outside than inside; only in the transitional seasons can you leave it open sometimes.
