I am sure there are posts about this but I am wondering if anyone can give me some advice on Radiant Barriers? I have researched and see that the foil type is much more efficient than the spray on. I am looking for info on companies and if it truly did lower your energy bills.
I am in Mansfield and just paid $550 to Stream Energy for a 2700 sf house.
Thanks for any information.

run a search here
and google on the internet

it is not the sq ft of your house but your attic volume that they price on--and difficulty
it also depends on your orientation and the ventilation in attic and other factors

last winter I had quotes of about .65 a ft for my attic--larger house/2 floors/good attic ventilation
we decided not to do it this summer and just see--we had moved into the house in Dec and wanted to see the bills before deciding if it was worth it

Yes, although both work much better than an untreated surface, foil type RBS is marginally better than spray-on (foil emissivity close to 0.05, spray-on closer to 0.2). But considering the difficulty of installation for foil types, blockage of cell phone signal, and low durability, as a facilities engineer, spray-on is the way to go. And though attic ventilation is helpful (studies show there are some benefits of 150:1 in hot/humid climates over code-minimum 300:1 SF/vent SF ratio), radiation onto the attic insulation is the predominant mode of vented attic heat transfer in the South! Fact. Attic ventilation does relatively little to overcome this... As does even forced ventilation, which also usually does more harm than good by sucking conditioned air out of the conditioned space through gaps in ceiling, recessed fixtures, etc. Fact. Sadly I've read a lot of mis-information on this subject today, most of which from this website! For real answers if you have the time to read, please visit buildingscience.com. Incredible wealth of sound knowledge there, and most of it is free! Even as a building professional, it has helped me immensely. Please feel free to contact me if I can help further.
