Q:

We recently remodeled the kitchen in our 1954 brick ranch and discovered only "Insulite" fiberboard insuation was used.  My understanding is that is only an R-1 rated insulation, so when we replaced the drywall, we added R-15 batt insulation.  My question is, how do we insulate the remaining walls of the house without replacing all the drywall?  Is this possible?  What's the best way?

THANKS!

Mary
