Not to ask a dumb question, why R-13 why not R-11 or R-15?

Is there a advanage going with R-13?

What would you put on the cileing?

My nieghbour insulated his garage thinking that it would be warmer......without heat the garage was actually colder as it keep the cold in, because it did not warm up during the day. Oh those cold winter days are back...

It really depends on what you want to do with the shed and what the climate is like in your area, are you heating and cooling the shed? If not I would leave the insulation out.

R-13 is the median between the R values for 2x4 walls. It is generally the standard, in my area at least.

R-15 has more insulating fibers in the same 2x4 thickness, R-11 has less.

Oh, I should also mention that everything from the plywood to the sheet metal that may be on your shed has an R value. Plywood sheathing generally has an R value of 2.5 while if your shed is aluminum the panels will probably have an R value of 1.

I live in Northwest Ohio and yes it gets cold here, that is why I need to insulate it.

This morning it was 25 out, so Winter is on it's way.

I do have electric in it and am looking for the best heat source that would heat 200 sq.ft.

Like I said what would be the best insulation for the ceiling?

Yes I am looking to insulate my garage also.
