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.?
Any help would be greatly appreciated.
