Mine touches the floor. Have about a 3 inch gap at the top. I wanted air to come in from the top.Dean, so your curtain does not quite hit the floor?
OJ, yours is a little long so the bottom is against the floor?
I do need to let some air in because the fans will be pulling from the curtained area, with the inlet air to the building on the other side.
My strip curtains arrived months ago, and I finally started putting them up. When I was a model building kid, I'd come home from the store tear open the package immediately, then lose half the parts before I started the build.9'6' tall. I didnt go all the way to the ceiling. I built a little frame that the the rail bolts too. I think the positive pressure help keep dust down, although, who knows. In the end its still a garage! I used to get air turbulence in areas of this garage if that makes any sense. I'm hoping now that the booth area is a rectangle shape it will help stop that from happening. IM excited to spray something. later this week.
