Hello everyone,
In our house, we have a double-wing patio door in the living room and a single-wing door in the kitchen. Now we have to decide between a standard threshold (about 8cm (3 inches)) and a low threshold (about 2cm (0.8 inches)). The lower threshold would come with an additional cost.
It seems that the higher threshold is more common among members here. I wanted to ask if anyone has a low threshold and how their experience with it has been.
Regards,
Alex

I’ll try to explain, but please keep in mind that I am not a window manufacturer (which is why I borrowed information from Kömmerling & Co.)
There are lift-and-slide doors and parallel-slide-and-tilt doors (PSK).
Lift-and-slide door:
The sash of the patio door is lifted by turning the handle. This lifts it out of its sealing position, allowing the sash to slide easily on its rollers or on a trolley. Depending on the design of the lift-and-slide door, the sash can also be locked at any position. To do this, simply turn the handle and lower the sash into position. When lowered, the door presses back into its sealing frame.
In principle, the lift-and-slide door works excellently. However, as it ages, problems start to emerge. The tracks must always be kept absolutely clean, and the handle needs to be kept smooth with good lubrication.
PSK:
The large sash of the patio door can be easily slid in front of the fixed side panel. This can cause problems if the sliding track is not kept clean, since many doors have this track on the outside where dirt and leaves can fall in. The door’s design requires that at least two elements are installed, with the second element being fixed. This is necessary so the movable sash can slide in front of the fixed element. The movable sash can be easily tilted for ventilation. However, the larger this sash is, the more the frame is stressed.
Because the PSK is not mounted on rollers, it is less prone to wear from frequent use.
It is often stated—especially in promotional brochures—that lift-and-slide doors are the better option because they are less prone to issues and so on. From practical experience, I know this is not necessarily true. Many lift-and-slide doors just manage to get through their warranty periods, after which the first problems with the rollers appear (which even I, as a layperson, can understand since the window elements are quite heavy). Our building contractors have therefore started advising customers who want sliding doors to be aware of the susceptibility of the rollers, without repeating the marketing claims but providing impartial advice.
Whether the PSK is more or less expensive than the lift-and-slide door basically depends on the pricing of the respective supplier.
Best regards, Bauexperte

Sorry, I don’t understand this now. What do you mean by sliding element? The lift-and-slide door was already expensive enough.
The windows have long been installed, so nothing can be changed anymore.

nordanney26 Mar 2015 11:59Well, you don’t have to do anything. It’s your decision what you want the landscaping contractor to do.
Earlier, I looked out the window towards the backyard. Two more houses (already occupied) are currently having their patios (paving) installed. Again, both have a threshold-free exit. It also doesn’t appear that any channel drains or similar are being installed there.

Doc.Schnaggls26 Mar 2015 12:24Alright, now I understand it as well.
@Bauexperte : Thanks for the explanation.
We deliberately chose the lift-and-slide door because the alternative tilt-and-slide door seemed somewhat "flimsy" to us, and due to the weight of the movable sash and its tilting function, we had concerns about stability...

Dirk
