Any experiences of Slide and Swing doors?

[ThePoplars]

On our extension, we are planning on having 4m of glazing on the south facing wall to overlook the garden.  We have UPVC french doors on the same wall in the existing building and have a running battle to try to get them to close because the sun makes them warp.

 

We've looked at, and discounted bifold doors.  However, we have come across the Magnaline product being used in Slide and Swing (or Slide and Stack) doors from New Wave Doors, Deceuninck, Panoramic doors, and other suppliers - although at this point, I'm not sure if it's the same product just licensed to different suppliers.  

 

Does anybody have any experience of these Slide and Swing doors, and particularly on a south facing wall?

 

Thanks
