Thinking of doing my own house in spray foam. Underside of roof deck and rim joist only. Got similiar quotes for icynene and lapolla open cell .5 lb product. Interested in the positives and negatives some of you may have encountered. Can't afford the closed cell product but house is not insulated very well and drafty. Expecting the srapy foam will find those drafty spots and seal things up better.

Personally - that's a very bad idea, but without your location (hint, hint - profile), specifics, what your goals are, etc... it is hard to answer. You need to start by pulling a search here about closed cell foam, open cell, roof decks, etc... You have a lot of reading to do

I know of a few threads I participated in where I mentioned Demilic in them (if you use the advanced search feature) which will also have a lot of other resources listed in them.
