:rolleyes: Hope someone can help! A second story room is MUCH colder in winter and MUCH warmer in summer - was finished out after we bought the home... have had the duct worked checked out and is OK and the attic insulation is acceptable I am thinking that I need to " add " more insulation - How do I add more insulation to a room that is already finished ? How do I get behind the walls ? Is there a "paint" product that would insulate the room? Thanks in advance!

If you are talking about the walls, there is a blown-in insulation that can be injected into the walls. The only problem I see with this, is knowing where more insulation is needed and how much is enough: you can't see inside the walls. Was insulation installed before it was finished? How is the attic insulation acceptable? To what R-value?

I heard a man on a radio show discussing this and a contractor called in and suggested adding 2 x 2s to the interior and adding another layer of insulation then drywalling over that. I don't know if you want to go to that much trouble, though.

I've also seen on home improvement shows where they cut a small hole in the wall and blow loose fill insulation into the cavities.

Good Luck!

Your most cost effective insulation upgrade would be to add more insulation to the attic. You did not say what is up there now be adequate isn't really clear. R30 or higher will be eay to install compared to opening up a wall or adding 2x2s. Do all of the other enegy stuff too such as caulk windows and doors, add a temporary shrink wrap barrier to the windows.
