Bifolding door sight lines are the physical dimensions of your bifolding door. Some doors are slimmer than others and provide information on their sizes in four part of the door. These are:

  • The height of the threshold and the bottom of the door.
  • The side dimension from the outer frame to the glass line.

Schuco bifolding doors comprise the finest German engineering and are one of the slimmest folding doors you can buy.

Is a bifolding door sight line important?

It does not matter what size your doors are. The important thing to remember is that bifolding doors have to be aesthetically appealing to you. We have customers that prefer the thicker aesthetic of our AluK doors and others that are set on the slimmest type of door.

The number of panels is a consideration as well. If you are thinking about a two or three panel bifolding door then perhaps the slimmer door will be better. The larger the doors, the less impact the sight line has on the product, because the doors spread over a larger area.
