ᐅ Experience with Kneer parallel sliding door

Because PSK windows are significantly cheaper and can be tilted.

One more function and still more affordable? – that alone should give you something to think about.

I – mind you, as a former aluminum window “factory owner” – consider tilt-and-slide doors to be somewhat of a joke, which almost inevitably tend to become increasingly difficult to operate due to their design. Of course, you could mitigate this by only using premium components. But then no one wants to pay for that.

Sliding doors are usually chosen when a wider opening is needed than what could be solved with double-leaf hinged or tilt-and-turn doors – so the weight is correspondingly higher. Adding a linear sliding motion to the hardware needed for tilt-and-turn sashes is no easy task.

From my perspective, this product seems tailored to a manufacturer who wants to secure service revenue down the line. I would think very carefully about that.

Do you really have so few operable elements that you need to overload them with functions?

One of my aunts had something like this (as a window) in her (high-quality) conservatory. I’m not an inexperienced user, but I always found operating it noticeably strenuous. Don’t let advertising videos deceive you; those are often made with perfectly adjusted fresh samples.
