ᐅ Can a lift-and-slide door be as airtight as a standard door?

Created on: 7 Aug 2021 10:37

We have one lift-and-slide patio door and will soon be getting a second one.
I like them because sliding doors don’t get in the way, they are easy to operate... and even people unfamiliar with the mechanism can quickly figure them out.
But sometimes I wonder if the brush seals can really provide effective insulation 😱
I’ve read that nowadays they are very tightly sealed 🙂
I would be interested in a comparison of the insulation performance of lift-and-slide doors versus “regular” doors.

I have been looking for this information for a while without success... 🙄
Does anyone know a website where I can find information on this?

I hope it’s due to understanding the door mechanism

More likely due to not knowing this mechanism :P
I’m familiar with some sliding elements from the 1980s, those slide smoothly 🙂

(The brush seal is not the actual seal but probably mainly helps against dust and insects)

Last but not least, the brush seal also deals with the (including acoustic) sand in the gearbox ;-)

There are no fundamental problems left to solve, so good models can be found.

You also have a free choice to that extent, as far as I know there are no manufacturers with significantly different design philosophies (or they make PSK rather than lift-and-slide).
