My husband and I bought a 1929 home a couple of years ago. Last year we replaced 12 old windows. This year we are planning to re-side with fiber cement, and I'm wondering what we should do about insulation in the process. I know that there is no insulation in the crawlspace/attic, so this is on our list, but there seems to be a lot of back and forth about what to do with old homes in terms of exterior wall-insullation. I doubt that there is much, if anything, in the walls.

We live in Westchester, NY, so this means frigid winters, hot, humid summers, and crazy heating and cooling costs...

I know nothing about these things, so it's hard to sort out fact from fiction with all of the internet links these days.

I feel as though we should at least do SOMEthing while the siding is replaced. (Obviously the house will be wrapped before the fiber cement goes up.) I just have no idea of what to ask for/look for, that will be the right choice to prevent future issues...

Thoughts???

Any help would be much appreciated!
