If you do, what kind are they, and what is the profile like?
I'm looking for bifolds like Solarlux ones (but cheaper!). I've looked at Origins, Kloeber and a few others and they all seem to have join lines on the doors, which I would prefer to avoid. Solarlux ones don't have any joins, they are completely plain and simple.
Would love to find an alternative so I can get more than one quote!
