Default Insulation and heating question on shops

Ok I'm getting ready to start on my shop and have a question. I want to heat my 30x55x14 ft shop so I don't have to winterize the boat anymore. From the bottom of the teases to the peak of the roof is only 4'9 so there isn't a ton of space up there. Will putting in a ceiling make that big of a difference? I am using r-19 insulation All the way through the shop and covering all the walls with plywood. Someone suggested putting some ceiling fans up there to circulate the air back down. Any thoughts?

I would go with a ceiling up of some sort and make it white, just for immense difference it makes in lighting the place to work in. Ceiling fans are also a must if you have 14' or taller walls imo. Our shop at work is 48x60x16, white liner steel on the ceiling, white spray foam on the walls, heated with tube style radiant heat. Love the radiant heat, warms floor, objects, etc.

Yes it will make a huge difference, heat rises. Just insulate between trusses and put plywood or something on the ceiling as well. The fans will help also being 14' high.

Builder wants to put up a metal ceiling instead of plywood... Said he will have to use extra 2x4 bracing on the rafters and somethig about sagging... What did you all use for ceiling?

Check your local codes. Some places require sheetrock walls and so on over insulation. If you have spray foam insulation any place you NEED to cover it with something. The stuff is SUPER flamable and very toxic when it burns. My place in Maine is made with SIPS panels and I tossed some of it in a fire. The flames and heat were amazing!

If you do infloor radiant or radiant tube heaters you won't need ceiling fans, if you install forced air unit heaters or a furnace they are a must.
Put as much insulation as you can in the ceiling, r30 if you can.
Inulation is an investment that will pay you back every year you heat the space.

Your builder should be able to put you in contact with somebody that can get it done right the first time. Its not rocket science, but their are a few things that need to be considered when it comes to heat. Good luck.
