In the EZ-Cool FAQ's:
Q: What is the R Value?
A: Down = 13 Horizontal = 9.6 Up = 8.1 This is better than 2" of
fiberglass insulation.
Not sure what the different directions mean.... Direction of heat source?
Can't see why up and down shouldn't be the same unless it is because heat
rises 'through' the material.
The product appears to be the same with perhaps a different nominal
thickness
3/16 vs 1/4; R13 v R15.6; but as you say - less expensive for more
R-factor.
I probably only need a 25' roll but for only $20 more... why not - could
double up some of the worse areas (firewall; tranny cover, over exhaust
system)
Thanks
Carl

Not I. But I would be more impressed if they talked about R-value (how well
it insulates) rather than how 'pure' the aluminum is. Pure aluminum is an
awful metal, it's only usable when alloyed with other elements. And of
course it can't actually be pure aluminum, since pure aluminum almost
instantly oxidizes when exposed to air (giving it a layer of aluminum
oxide).
I might be more inclined to go with something like:

since they do talk about how well it insulates (R15.6 is very good for only
1/4") and it's cheaper as well.
But I just use the foil/felt stuff from Home Depot. If it gets wet, I take
it out to dry, just like the carpet.
