Question

I have a 2-story home with very little insulation in the rafters between the 2 floors. Would you recommend adding more?

What would you recommend? Would foam insulation be okay? What if we have to reopen that space to do the work?

Answer

Jerry,

In a two-story home, it is not necessary to install insulation between the floors except as soundproofing.

With a well-balanced system, the heat transmitting between the floors will aid in the heating of the upper floor, reducing the necessary amount of heating directed by the forced-air system through its ductwork.

Now if you have attic space above the first floor, I would recommend at least an R-40 or the minimum required by your local code. I usually do not recommend spray-in foam in a ceiling condition in an attic unless it is an unventilated hot deck installation.
