I have never seen this type of material. Is the foil applied to the underside of the roof or on the attic side of the ceiling?

It can be installed either way you described.

Thanks for all the feedback. I wasn't that interested in the savings as much as lowering the temp to help protect things I will be storing in the attic. It seems like its a very good product for that usage. Thanks again.

I've been up there to do some work and you can barely manipulate around never mind do some kind of a nice job installing foil. I'm a former HVAC installer and I'm real skeptical about what kind of job they can do not to mention the compacting of your insulation that must occur.

I agree with everything you said. I think someone trying to work in one of those type of attics ,would make a huge mess of the insulation up there.

Just a comment....We just moved here from AZ, where the sun produces ALOT of heat in the attic. The house we bought there had the foil radiant barrior, which we thought was a good idea....until we moved in and started having cell phone reception issues. The foil blocks the signal, and we constantly missed incoming calls. Outside it was fine, inside very poor. Just a note to anyone before you decide to have foil placed in your attic over the house.

I was crawling around up there last week to add an electric run, it's a pia to walk beam to beam, U can't see where you're stepping.

But the fluff fills right back in where your foot was.

When U get to where you need to and do work it does get disrupted for sure.

Almost need to bring a small rake to get back nice.

I would guess that if U hire someone to install the foil they mess up a lot it and don't reset it.

Oh at 10am it's really hot up there later must be unbearable.

Someone suggested a sheet be laid down first or a board????

Oh and you need a mask!

I'm skipping the foil idea that I thought I would do later.

I'm working on a new type attic fan design that can push 1,000 cfm each.
one or two of those on a temperature driven on/off switch say at 75 degrees looks like an easier way to go.
It should cut the attic temp down 30-40 degrees.

The fan(s) can run off 110volt or solar.

1000 cfm and solar???

Thanks for mentioning.
