All good until Jon walks through the door with an 8’- 2x4 to cut and blows a nice hole in the new ceiling while spinning it around.
Just saying
I would for sure do that!
My shop was built with scissor truss, that gives me 8’ at the wall and 11’ in the center, love the height. I have sheet rock on the ceiling and have to find wood to hang any thing from, the walls are 7/16" OSB and that works great I can screw any place I want. The options are endless and not all works for every body. I would use what works for you and do it the best way as it is cheaper and easier then doing it over. I don’t think 1/8" any thing on the ceiling is going to work good it’s going to sag even 16" centers not as much but still sag.
I don’t think there is ANY right or wrong answer here. It comes down to recommendations and helping to prevent …geeze I wish I would have done that the first time?
My shed is 12x20 and I use a single 15,000 btu Mister Heater on 20lb propane bottle. It has worked quite well for me over 15yrs.
I assume you only heat it when you are going to be working inside. I need heated storage 24/7. It doesn’t need to be maintained much over 45F when I’m not in it. My furnace choice is a 16,700 BTU wall furnace. The propane company says I need 2 100# tanks, but I think I can probably get away with one if they will do it.
Way over here in York Jon, the 100 gal tank rental for a year was $10. in twelve years the rental is only $120 per tank, as long as they fill it.
I tried to place the materials order this morning, but I misplaced my Home Depot card in the move. By late afternoon I had located Marilyn’s card, but by then, the person at the Pro Desk who was going to help me get the financing deal that they aren’t currently offering had left for the day.
I decided to rule out any 1/8" or hardboard product for both walls and cieling. I had decided on a 3/8 primed plywood, but I can’t get delivery as the “local” store does not have it. I looked at sanded plywood in 1/4 and 3/8, but needing 26 sheets total, I ruled it out on price. I’m not an OSB fan, so I went with 11/32 BC Sheathing for both walls and cieling.
The gas company approved my plan after I moved the door…
The tanks will be at the left front corner and, for code, need to be a minimum of 5 feet to the door. This allows the 16,700BTU furnace to be mounted close to center on the back wall.
It might actually happen soon!
OK, Governor Overthink!

I’m really getting in to the layered plywood look for the front wall.
Gotta make use of all the cut offs !
Today I finalized the materials order. Two trucks coming next week!
Now that it’s really happening, I began light demo by removing the wainscoting and all the trim on the front…
I don’t think its a show stopper, but there was quite a bit of rot hidden…
Most of that bottom plate is still very solid after I broke away the dry rotten wood. If this was a sign restoration, I would soak it with wood hardener and patch it with wood and bondo. This area will not be seen, so no bondo needed. I will probably patch the floor because it might fall under the door threshold.
The balance of today I’ll prep areas to receive thirty two 4x8 sheets, thirty two sicks of lumber, and 7 bales of insulation! I just now noticed the count of sticks and sheets was the same!
Put a good roof on it , vinyl side it. Call the exterior done.
Stuff is about to get real…
That’s only part of the order. Door, window and furnace on a different truck.
I don’t see any bandages … 
Right on man!

Once I got the materials off the pallets and organized I started in on finishing the paneled area. This is where the furnace will be installed, so it needs to be done early.
It might be hard to see in this picture, but the right hand edge of those t&g boards is very random. They also don’t fall on a stud…
I started by trimming the ends of the paneling straight with my 5" circular saw. Once that was done. I added supports for vertical boards on 16" centers…
Insulation was cut and added to each section…
Then the verticals boards were added…
Once framing is in place, there will be one more horizontal board added to match the height of the verticals to bring the wall up to cieling height.
I still don’t have the furnace, door or window. They are waiting on other items to arrive before shipping it all together. I may make the hour drive to Altoona to pick up the furnace.
Atta boy, Jon!
