exposed ceiling rafters

Ok.. I just took down a partition wall and I discovered my rafters. So now I want to remove the sheetrock and expose the rafters. What is the standard procedure for insulation between rafters? foam board and then sheetrock?

Any help and pics would be great so I can sell the wife on making more of a mess.

Here are a couple of threads with information about exposed rafters:

Where's your house? Unless you live someplace with a very mild climate, where the sun doesn't beat down on your roof, it might be tough to get enough insulation in place to overcome winter heat loss and summer solar gain. Icynene spray foam (http://www.icynene.com) claims an R value of 3.6/inch that doesn't decrease over time, and has other benefits (like a continuous water/vapor seal; but your rafters themselves would allow some water and gasses to pass).

Good luck!

How finished do you want it to look? And how deep are the rafters? I'm sure that you could install rigid board and fill in any voids with a spray foam - and you'd have a nicely insulated roof. If you want the wood rafters to remain unfinished/unpainted, then drywalling between each rafter would make sense. But depending on the rafter type, it might be a pain.

If you insulate and then paint everything, you'd have more freedom in the method of insulation. Many commercial spaces install isulation in their steel roofing system and then hose is all down with white or black paint. We did this in our basement and it worked well. I did have to add extra insulation (the pink stuff) at the rim joist - paper side out - in order to paint that area. I covered the plumbing and duct work so that they remained unpainted.
