Re: Possible alternative to Reflectix?

So where reflectix is a bonus, why not use just the attic reflective on top of the foam, cheaper, thinner. Does it's job without trying to do the foam's. Save the expensive reflectix for where I can't use the other stuff.
I am thinking 2 layers foam, 2 reflective, same as you basically, just in thinner layers and without the bubbles. total thickness 1/2-3/4"
I want the foam for it's sound deadening/impact(my head against ceiling/beams).

I wonder if it would be more efficient to have a layer of reflective on the inside, since it would reflect the energy before it warms the insulation and turns to conducted energy instead.
