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

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?

Sealing gasket – of course.
When lowering the door, a gap appears at the top that needs to be sealed somehow. You can only see the brush seals, but those alone certainly can’t make it airtight...
... at least that’s what I assume.
A blower door test would probably reveal a lot of leaks in our 1970s house... 😉
But if one spot is sealed, it’s already more airtight than if there are drafts everywhere...

We had triple glazing in our own profile system, which was designed many years ago by the now-deceased company founder, but not on the lift-and-slide doors; those had to make do with double glazing. That was partly why we decided to become licensees instead of continuing as manufacturers.
