Important notes for the DIY... ALWAYS leave an air space on both sides of the barrier. If you don't, heat will conduct through the barrier and your results will be less than optimal. NEVER seal edges and seams. Your structure needs to breathe.

Actually there's sufficient "ir space"within the fiberglass. laying the RB on top of FG will not cause it to conduct. I have proven this time and time again with a heat lamp.

Otherwise you are 100% correct

I've been installing the e-shield product here in Fla for 2 years and all my customers see a 30-40% reduction in their energy bills once it is installed i swear by this product.

Radiant barrier

We use the "2 ply" RB with fiberglass in between the RB being a in the ohio region i am not sure the how effective it is in this area for "conventional" attics. we use it mostly for "Cape Cod" type of home and have seen great results.

i guess thsi stuff is like having lowE glass in your attic? if reflects radiant heat from the heater back into the home and in the summer reflecting the radiant heat back away from the home?
in the attic,does this stuff go on the floors or just the ceiling? can it be used anywhere else in the house?

i firmly believe that the reflective barrier is going to be far more effective in retaining a cooler temperature in your home then trying to achieve a warmer one...in the case of trying to warm the home, it won't be cost effective...down south, where your cooling season is longer and more extreme, definately worth the investment

is the radiant barrier best layed on top of the insulation in floor of attic or in rafters?
in the northeast, can radiant barrier be detrimental in any way?
what if you have a small roof leak, can the radiant barrier get ruined if its wet?

Either or. Depends on the which product used, and the circumstances of the home.

well no air, no water vapor,no condensation
depending on the thickness the dew point should occure somewhere in the middle of the foam

a more viable insulation then the smoke and mirrors of radiant barriers

Well spray foam not only voids the warranty on all roofs if applied directly to the roof decking they have a virtual perm rating of zero. EShield has a perm rating of 13 which allows moisture to pass through freely. It is the only attic radiant barrier out that does so.
