Lets keep this simple for those unknowing of btu loads. WAP is a federal low income program for energy efficiency in a home. Go search the DOE for NEAT, software that WAP administrators have to use that calculates whether an item will have better than 20 year payback(even though the avg. person lives in a home for less than 10). Foam isn't even an option. Go ahead, look it up. That is evidence it's no comparison to the insulations chosen 9/10 times. Fiberglass.

@spraymaster77 Tell me super sprayer, that makes you like a drywaller, LOL, or concrete guy. Wow one of my 10 subs. LOL good job. Not "got a/c license, BPI license, HERS rater licence" on that list? So you don't know how to calculate btu load? Thats what I thought, let the builder tell you what he wants for insulation, because we know ROI, and proper building techniques, you know insulation.

@spraymaster77 Get a license involving btu load, then talk to me, I am getting real sick of spray foam contractors acting like they know SHIT about btu loads.No A/C guy I know installs foam, but I know many that install any loosefill. They know that loosefill is SUPERIOR at a lower price, just takes REMdesign or some other type of btu calculator, ASHREA. I have honestly tried near ever type of foam installation in my ROI calculators, it has extremely poor ROI.

@HomeEnergy wtf is wrong with you, I have been in insulation business for over 30 Years. Owner and Operator & yes salesman. I provide my new and existing custmers options. Good luck cause you need it more than i do.

I do not know MR home energy or care too, Maybe he has some almost new but trashed foam rig for sale he be talking about. Holly Shit he is a builder.

I have sprayed foam for homes,business,uncle sam, joe blow,hvac. refers ect. home energy now not later

I don't worry about the fiberglass absorbing, because if it were a foam home, it wouldn't ruin the insulation, it would ruin the lumber holding the home together. Its good that fiberlass alerts you to a moisture problem, the problem is the moisture, not the insulation, and its a hell of alot easier to replace batts, than walls/rafters/floor joist/rotted sheating w/foam on it. You don't want vapor barriers in houses DOE can explain why, it's on their site. Air barrier insulation also a bad thing!

[HomeEnergyNow]

@GB3RND There are a few good places for foam, like commercial buildings in a big city where space is limited/expensive, or maybe 1/5000 homes, and only in a few places. If the ceiling is already low, and there were 2x4 or 2x6 rafters, you cant stop the bridging w/out bringing the ceiling down with rigid foam, dont finish the attic! It is a really financially stupid thing to do to a house anyway, spend 3 times/sqft what you would for a new home.

[GB3RND]

So it is better to lower an already low ceiling, or just skimp on the R-value to use fiberglass, then hope that a pieced together plastic sheet vapor barrier with staple holes all over will be more effective at preventing moisture ingress into a very absorbent material (fiberglass). Why not use a material that does not effectively absorb moisture and is a vapor and air barrier and has a higher R-value to maximize head room in an already low ceiling situation. Then what about those Box Sills?

[HomeEnergyNow]

Picture a 2x4 rafter with your R-21ish closed cell in between them. Why a almost vapor barrier is a bad idea, humidity in the house floats to the upper upper story, and goes out the easiest way it can....through the 2x4 rafters. Now in the middle of winter the 2x4 rafter which is like R-2, gets to be real cold at night, and the homes humidity is wicking out, hmmmmmmm, Condensation anyone?I would NEVER leave a 2x4 or 2x6 to thermally bridge in a second story ceiling, especially w/out ventilation

@GB3RNDWindow manufactures void their warranty if you use foam around them! (yes, even the "window" stuff) When we are done, no warranties are void. Go to the national OSB website and tell us what foam will do to the warranty there too! I use whatever has the best ROI, not what performs best in a 2x4 cavity. I understand gold is the best radiant barrier, but would I recommend it? Never could foam be the correct product, I explained you can NOT rely on mechanical fresh air! Health FIRST
