E-barrier is a new product from Sherwin Williams, it is sprayed (can be rolled and
brushed) in attic spaces. E-barrier is a reflective coating for attic decking, keeps
winter warmth in and summer heat out. An independent test by Sherwin Williams
claims a savings of 15 percent in heating and cooling cost. It cleans up without the
use of chemicals and dries quickly for a second coat. It also does not trap water in
the wood, its breathable. I have never used this product but am highly impressed
already. My only question is the cost? Also has any one used this product, any
pointers when spraying a attic space or is it as straight forward as I think it is.

Having crawled around in our attic more than I like to think of, I can tell you that, at least in low pitch (eg, 4:12) attics, nothing is "straight forward".
I am sure its hard work, but it sounds like a lead generating money making opportunity.
What?
oops sorry.
Put a tavern type response to DanH's oneliner which I shouldn't have in a serious thread. I'll delete it.

It's not that new. My dad mentioned it to me a couple of years before he passed in '01 and I think it was close to when I bought my house, so that would make it about '97. It is intriguing, though, especially for a house like mine, which was built in '46 and would be a PITA to re-rock.
how much a gallon
I don't remember but it wasn't cheap.

Yeah I just read about it on the web site did it really make a diffrence in your heating and cooling bill?
I didn't use it, just normal paint. Maybe the next house, unless I build and then it'll be really energy efficient, anyway.
"I cut this piece four times and it's still too short."
We have used on three projects and are proposing its use on the next remodel. On the first house we used it on, the owner was able to lower the thermostat substantially in the summer to keep the same level of comfort. I think his settings went from 65 to 75 degrees in the summer. I personally noticed a significant change in attic temp almost instantly.
It is relatively easy to install, but you will want to buy one of those extended arms for your sprayer. That allows you to be relatively comfortable while spraying the lower portions of the roof. If I recall it was around $50 per gallon.

Thank you!
I'm guessing a gallon covers less than with regular paint?

Dan,
For some reason, 400 sf per gallon is sticking in my mind, but I cannot be 100% on that. I usually estimate 10% less than sticker and round up to the next 5 gallons. We markup this work more than other because, frankly, it is not fun to do and most are not willing to do it. Depending on the attic space, I would budget two guys-One spraying the other managing a good light to make it easy to see around the attic. Be real careful around attic light bulbs, the overspray is enough to have them explode.
The other thing that I have found is that the larger the rafters the more difficult is seems to spray-mainly on the exterior bearing walls. So factor that into your equations. Also be careful of overspray out the soffit vents.

I heard about someone who did it :-)
Think I'll be a space man this coming Halloween :-)
