ᐅ Lift-and-slide door or two double French doors for KFW55 standard

A good alternative would also be folding glass walls.

Advantages:

• Complete opening across the entire width

Disadvantages:

• Higher cost
• Some space needed for opening and closing (ours fold outward)
• Risk of pinching fingers (might be too risky for some parents)

Given the options, I would prefer the sliding solution.

I have a lift-and-slide door with a sliding section that is 2.50 meters (8 feet 2 inches) long and floor-to-ceiling. I would much rather have a regular door and the rest as a lift-and-slide door. I find it annoying to always have to open the sliding door. If a regular door is also 5000 euros cheaper, then I really don’t see any reason to choose the lift-and-slide door at all. Doors don’t look bad anyway.

.., additionally, two double flush doors provide the option to use or separate the rooms differently.

It will just be a lift-and-slide door
the width will be about 5m (16.4 ft), so 2.5m (8.2 ft) per panel

I have exactly that—a 5m (16.4 ft) wide triple-glazed lift-and-slide door divided in the middle. And I have several children.
I’m happy to share my experience:

Reconsider the disadvantages: children can’t push the heavy panels

We moved in when our middle child started school, and this child, who had never used a lift-and-slide door before, was able to open it easily after just one explanation. Adults and older children compensate for lack of technique with strength. Therefore, I assume even a 5-year-old can open the door with the right technique.

If you can wait a few more years, I can tell you when my currently 2-year-old opens it by herself 😉

At an age when they can’t manage it, it’s probably a “feature”; at least I wouldn’t want a toddler alone with it.

Only partially true—a simple two-word command like “door open” is enough, and the older siblings willingly open the sliding door for the little one. Flipping the lever to lower the door works once the kids can reach the lever.

Pinch hazard, since you have to watch other spots (at the bottom). That’s something little kids usually haven’t learned yet...

None of my children have ever gotten pinched, not even the 2-year-old when the older siblings close the sliding door carelessly.

I would choose the lift-and-slide door again anytime.

My daughter (with children) rejected the large sliding doors after experiencing more than once that children couldn’t tell whether the sliding door was open or closed. One child ended up in the hospital. Personally, I find hinged doors much more comfortable.
