Large Garage Doors5/16
This past week I was asked to price a pair of 8' x 9'6" (total opening 16' wide) out swing garage doors. After a quick look, I decided not to get involved. The design was a traditional look, small transom type window on top and large v-groove panel on the bottom. I thought there were a couple problems with the design. One, all the stiles and rails were drawn at 6". Which I thought were too small for such a large door. Two, the panel area, which was 6'6" tall x 7' wide, had no cross braces.
So, that is the gist of the project and this is my question(s). If you could design the doors the way you wanted, would you do it? Could you do it? Have you done it?
Maybe if the drawings had specs for hinges, latching hardware and what would happen if one of the doors was left open on a windy day?
The historic approach to that opening, at least in the old neighborhoods I serve would be a fold and slide door system.
I've wondered how a door with a super beefy hinge stile, like 4"+ thick x 8" wide, and long, thick double tenons, and rails that tapered down to standard thickness as they approached the strike stile would hold up. If you made the reference face the outside, everything would look the same from that perspective.
Outswing doors in my climate will not work due to snow piling up and blocking the path.
However, I have a client that used heated hardscape to prevent any snow or ice build up, so we built four large paired openings for her - a total of 8 doors. Each door was 6' wide by 10'+ high, arched heads. They were to be hung on automated hydraulic pivots that were set below grade with linked actuators so the closing speed, sequence, etc could all be controlled. They were rabetted at the meeting stiles, so sequence mattered. 3-1/4" thick, they had a core of stiles and rails that were 1-3/4" thick joined with 4' long tenons, with faces of tongue and groove v-joint on both sides.
The hinges are the potential trouble point, next is the jamb and securing it to the frame adequately, then torsional twist. Your mention of wind is a very real concern. It would be best to have someone else spec the hardware and anything not wood - your neck will have enough potential nooses to dodge.
Your path of escape might include the fact that this a 'double' opening instead of a single, and they are trying to impose a single opening visual aesthetic - carriage house doors - onto a simulacrum. Recipe for visual disaster. It is also worth mentioning that this is never seen for a reason. It does not work.
