SW Iowa | Dad has a 14' tall by 22' wide bifold with straps that has been hanging on his Morton building for about 15 years now. It has been trouble free, and a lot less work to open then the sliders that was replaced. It has had ice on it, snow against it, and as long as the power is on, it opens. It needs a new brake as if you try and stop it on the way down it won't, but it holds up fine. This summer I put a new 18' tall by 35' wide one up with auto latches and straps. It is not any slower then the big hydro swing type doors I've been around, and when it was all said and done for the hydraulic lines and pumps, about the same price. I don't have to worry about vehicles setting close for the bottom of the door to hit, and I'm sure with 6' snow drift no door is going to open. I know lots will say Hydroswing all the way, but I have no complaints about the Schwiess bifold.
I do have on the sides of the shop an overhead type door, and it is faster and we use it for the smaller stuff, but you won't find a door as large as my bifold thats any faster open or closing, when it comes to heat loss. That is why the shop I built has three options for bringing stuff in. A large bifold, a 18' tall, 24' wide overhead that the tracks follow the wall up to the roof, and a 12x12 overhead for small tractors, forklifts, and pickups.
