Insulation .. but no drywall?
November 17, 2014 3:46 PM
What are our options for ceiling insulation for a ceiling that we can't drywall and paint?
We have a small clubhouse that has insulated and drywalled walls but the ceiling is not so for the winter it gets so cold we can't use it. Does a spray insulation exist that is clear so we can spray it but does not required painting or dry walling to cover it?

You're going to want to drywall over the insulation so you don't all die in a fire. Burning foam is bad. Why can't you just spray insulate, then drywall over it?

Cut out a three by three section of ceiling.
Get fibreglass batting, cut to length, shove it through the hole, manipulate between joists with long sticks.
Re-attach drywall, compound, sand, paint.

If you can spray it, then why can't you drywall it? If you don't want to rip away the old ceiling, maybe put rigid foam sheets over it and drywall over that. As said previously, you'll want to protect it from fire.

the ceiling is not
To clarify: does the clubhouse actually have a ceiling (i.e. a separate layer of something inside the roofing material) or are you looking up and seeing the inside of the roof? Photos would be helpful.

A suspended ceiling would give you some insulation value.

Yeah, if there is any attic space, your best bet is to properly insulate with the recommended R-value for your climate, using the method IndigoJones outlined.
If not -- say, you're looking at roof trusses and then the underlayment for your roofing material, then you really should consider having a ceiling installed, and insulate that.
If your roof is an angled one with a standard joist/rafter system, there are methods for putting insulation against the roof itself and then drywalling over that. Often you want to include an air gap to prevent ice dams, but there are ready-made devices you can use for that before you put in the batts or foam. This will give you a cathedral-type ceiling with or without exposed joists.
Otherwise you can just create an attic against the joists. If you have a truss ceiling/roof this is what you should do anyway (sometimes code requires trusses to be inaccessible so they won't get damaged, as this can be structurally dangerous). So you're back to the normal ceiling installation process with insulation on top of that.
Almost everything you need is right here. Your library may have this book or an equivalent.
