ᐅ Are sliding lift-and-slide doors generally less airtight?

Hello,

we are currently planning our house. We have planned a lift-and-slide door downstairs (partly covered) and would now like to add another one upstairs.

Our builder doesn’t strongly advise against it but said he wouldn’t necessarily do it because lift-and-slide doors can sometimes let in some water during severe storms. Both doors would face south; the downstairs one, as mentioned, is partially covered, while the upstairs one is not.

We get severe storms one or two times a year here, and sometimes also when we are on vacation. Since we plan to use wood flooring throughout, water damage would of course be very unpleasant!

I haven’t been able to find much information either in this forum or online about lift-and-slide doors leaking, which is why I’m still in favor of having the upstairs door.

What do you think? Are they really that problematic?

Best regards

He probably doesn’t want to install them. I wouldn’t let that worry me; there are plenty of good systems available.

Ours is watertight. It even holds when the kids spray it with the garden hose.

Waterlogging can become an issue. However, standing water should not accumulate there in any case.

Just install a facade gutter in front, and that’s it....

Our lift-and-slide door is sealed.
However, the DIN standard requires that measures against standing water must generally be taken in front of such doors.
Installing a drainage channel is sufficient, for example. In practice, this is often neglected.
