I have a 1 1/2 story home. The upstairs bedrooms get pretty warm in
the summer.
I recently bought double paned vinyl windows, This helped SOMEWHAT
last year.
Since it is a 1 1/2 story I do have access to all the outside walls
other than the window walls.
There is old insualtion in between the studs that are exposed. I have
access to all that. Easy to work on.
The insulation has PAPER on the one side that faces into the attic.
This insulation is old and worn. What I want to do it to get some
insulation boards 4'x8' x 3/4" with the foil on one side. Really like
to cocoon both rooms.
Questions

1. If I am installing the insulation board do I still need insulation
in between the studs on the wall?
2. If I need the insulation in between the studs on the wall does it
need to be with OUT the paper if I install the insulation board over
it...?
3. If I install the insulation board over the existing insulation
thats in the wall can there be moisture build up in between the new
insulation board and the inusaltion with paper on the outside of it.?

Everything I have seen says to encapsulate the uptairs. �Even plug off
the pathway on the kneewalls that are from the front of the house to
the back inbetween the floors. No insualtion in between the floors but
plug iff so no air can travel �in between the floor.

Any help would be greatly appreciated.

The BEST INSULATION is expanding foam about R6 per inch, plus as it
expands it seals air leaks cracks etc,

yes and encapsulate the entire iving area
