I have purchased an 8 X 10 wooden shed. It has only the 2 front doors. No windows.
I plan to wire it for lighting, air conditioning, and heat. I was thinking of insulating the walls with batt insulation and covering that with osb. I was thinking I could make a ceiling out of the pink sheet insulation perhaps 1/2 inch thick and seal all the seams. I only need to keep this shed at a temperature of about 60 degrees year round, hence the heat and air conditioning. I know the walls will be fine but do you think I will need more ceiling insulation? Also since it is a portable building that is built on skids how do I insulate the floor or will I need to do the floor? I was thinking of putting a coating on the floor (plywood) that could be washed easily.
I live in Southern Illinois so we have mostly moderate temps with a few extremes per year. Does this sound like a firm plan?

 

Unfortunately gaps in insulation count much more than the places where it is done right. With just the 1/2" on the ceiling you will barely notice the insulation in the walls. Floors are difficult, perhaps a layer of rigid with another layer of osb or plywood.

60 degrees is almost the same as a normal house which we calculate at 65º. The extra 5º comes from internal gain. Cooling in the summer should be fine at 75º. Is this for people or pet comfort or other?

If you thermal break the ceiling will you also vent the space above it to reduce the possibility of moisture problems, or are you talking about insulating between the trusses and using the rigid foam as also the moisture barrier assuming that there will be possible condensation potential otherwise.

 

I am going to be raising rabbits in the shed. So somewhere above freezing in the winter and below HOT in the summer will be fine.
I plan to use the foam sheets as a ceiling, the shed has vents front and rear at the peak of the gables. I planned to fur down at the peak and make like a mini attic area.
So Bud you are saying even if I tape the joints on the foam it will have no insulation value at all...I will still lose all my heat or cool anyways??
I need a washable surface on the floors so I was thinking of caulking the joints in the plywood and using a deck or porch paint on the floor. The shed only has 6 foot sides with about 7 1/2 feet at the peak ( haven't really measured it). The siding goes all the way down on the sides so I was thinking if I block the ends with treated plywood to keep the wind out it might be ok without insulation in the floor.

 

Rabbits will go outside to do their duty, if you provide an opening. Inside in a closed space would be awful, believe me, our kids had to have rabbits, INSIDE.

As for the insulation, what you are planning should be fine with the critters, they are very resilient and will put on their winter coats. Heat in the summer might actually be tougher on them than the cold. A good nesting box inside their enclosure and they will create their own space.

As for washing the floor, I would put down some inexpensive vinyl flooring rather than just painting the floor. If you plan on shoveling out the inside, it will definitely soak through any paint job.
