Shop door questions
 
I am planning on putting up a shop in the near future and I'm trying to decide on the size and type of large doors to install. I know it has been discussed many times before and I thought I had my mind made up to go with a one-piece hydraulic door but now I'm second guessing my decision. Because I'm in Canada thermal efficiency is very high on my list of requirements and I thought they would be the best sealing door. I thought that definitely ruled out overhead doors but apparently not. the Overhead door company makes an 850 model that has 3" insulation for an R-value of 26 and they are available in widths up to 40'. Has anyone ever installed a very wide overhead door, and if so can you share your thoughts and experiences? I have also considered the dual overhead design with the removable center post but recently I have been informed that often issues with the center post arise as the building gets older and things shift slightly. One issue I am concerned about with both bifold and hydraulic doors is the ability to use them in windy conditions. Is that concern justified or is it a non-issue in anything but extreme gale force winds. I don't want to have a door that won't close on a heated shop in a - 30-celsius blizzard.

Door size is another thing I struggle with. Other than combine headers is there really any reason to go over 30' wide? Has anyone only put on a 26-30' door and really regretted not going wider? This is a shop, not machinery storage so I would only be driving the combine in to work on it. It wouldn't be a regular occurrence at the end of the day. The more I think about it I can't think of many instances that a larger door would really be useful and I suspect that maybe something like a 28' and a 14' overhead on the end wall might be better than one big one. If I do put in one large door I will have to put a small overhead on the side or in the other end just for vehicles and small equipment.

I didn't expect it, but at the moment I think the dual overhead door design is winning out by a small margin and in a perfect world, it would include the removable post concept.

Any and all advice and experiences will be appreciated.

I know nothing about these doors but see them advertising on facebook lots lately springwatermfg.com.

We have a fourty foot by twenty foot bifold door on our shop and love it can drive the combines in no wiggling or swearing and the shop has a 20 foot celling . I went to siast in Saskatoon in the AG mechanics course and they had the doors with the post in the centre which gave them fourty feet just seemed.like a.pain in.the ass. With our big door we just don't open it unless we need to in winter

How do you find it is for sealing up? I think it could be sealed up well except the hinge area might be a bit tricky. Then again I guess it is really no different than an overhead and at least there is only one joint to worry about. I really like the concept of the HP doors but because of the way they move, I don't know if they can be sealed up along the sides as well.

What type of building? Wood or steel ? If going steel the overhead with removable post won’t be a problem.

To be honest it's not a perfect seal by any means but does the trick.

For us anything over 25’ wide would be a waste because we can’t drive around with big headers on anyway. I’d spend the money on a bigger taller shop

We have a 40x20 bifold diamond door in our shop and granted it's very nice for bringing in a couple combines during harvest or the drill occasionally, for most winter days it's very impractical! If I had to make the decision again I would go with the two overheads and centre mullion option. I may be a bit paranoid but I'm always concerned about leaving the door open and having a storm knock out the power and not being able to close the bifold during a thunderstorm! Another concern I have is if the drive chain or sprocket was to ever fail the whole door would drop catastrophically!

Personally I don't like wide overhead doors, lots of weight and the wider you go the more difficult they are to track nicely, we have a 30 as the widest, it is always a pain. A bifold would be nice, because then you can put a man door in it too.

Oh god that is actually something that's happened to us where it wouldn't close. Wast a power issue though was an install issue the guy didn't put the "eyes" or laser safety things in proper and sometimes it wouldn't shut! Fantastic for leaving all your belongings open to the public. Fortunately only took our guy a year to fix it😲 but yea major downside
