Has anybody done a cost comparison between the various types of building insulations? Assuming a building's construction makes it feasible to use any type, what's the proportional difference in cost? Lets say it cost "$1" to insulate a house to a certain value using blown-in cellulose, how much would it cost to do a comparable job using polystyrene panels? Fiberglass?
Labor costs should be included in the comparison.
The comparison would have two sets of numbers for two situations: one for new construction, and one for existing structures.
I don't think the prices for the materials differ much for different parts of the US, so I don't think that's a factor. I'm not certain about this though.
This is just for theoretical discussion. I want to be able to contribute to a discussion, "Typically, polystyrene costs X times more than cellulose".
