I am trying to figure out which way to go with the insulation in my 1948 bungalow. After seeing some massive ice damning this winter (although no interior damage I can tell - knock on wood), I believe I need to insulate the upstairs.
Currently the roof has two gabel vents on each side and five roof vents across the very top (over kill). The room is hotter than h*ll in the summer and a ice box in the winter. The room is finshed off with wet plaster and has a heat register and cold air return. On each side of the room is the knee walls, they have minimual insulation on the floor and some fiber on the inside of the walls, cannot tell about around the top of the room.
One contractor says to use iceyene on the vaulted roof rafter, therefore making it livable from the top down. The other says to blow in cellouse in the knee walls and add two vents on each side mid way in that knee wall space and blow in the cap vents. I am so confused on which way to get this done.
To add to the mix, of course the downstair walls are not insulated but number 1 wants to spray retro foam and number 2 wants to use the celloulose, but that is a whole other story unless you got an idea on that, too?
Thanks in advance.
