I am adding some insulation to the walls in the upstairs of the house we moved into last year. I have torn off the old plaster and am down to the studs. I am running new wiring and have been just using fiber glass insulation with the paper backing. I staple it good and tight. Then cover the inside with a plastic right against the dry wall.
A local carpenter an I where talking at the lumber yard and he said to use spray on insulation. He said it seal the house up tighter and is way faster.
I have looked on line at the type you spray on shop roofs. I am also thinking of using it on a building that I am using a short term shop.
So here is my question: What is the difference between "high" density and "low" density foam?? Which one do you use where??
I see the smaller setups that have two tanks that are about the same as 20 lbs. propane tanks. They are not cheap but how far would they go?? The outside walls of a single room??
The next step up seems to be full 55 gallon barrels and that is about $2000 for the two you need. I do have a friend that has a spray unit that is for the barrels. He sprayed the ceiling in his shop. He does not know what product he used as he just used up what came with the used unit he bought.
I had an estimate for the shop ceiling to be sprayed. It is a 50 X 26 foot building. The quote was for $4500. I thought that seemed real high.
I really want to spray the building ceiling. There is not good way to insulate it in any other way. So If the same foam would work on the ceiling and the walls of the house I would just go ahead and buy a couple of the barrels. Then use my friend's unit to spray it all. With doing both I would be able to use up the two barrels of product.
