I am looking at finishing my basement and have an open ceilling which goes underneath my wood flloors. I wanted to know if I am going to insulate the basement and heat it do I also insulate the basement ceiling or to I leave it and just insulate the basement walls. Also how would you go about insulatiing the basement and what do you do to make sure there is no moisture that could create mold. david

The blown insulation in about half of my attic is pretty compacted down. What was probably about 8-10 inches of light and fluffy blown insulation is now even with the joists...maybe 4 inches now. That side of the house, the bedrooms, seems much cooler now that the temperatures are dropping outside. Does compacted insulation have less R-value? Can I add more insulation on top of the old to help, if so, what types of insulation can I use? Is there a way to know if the compacted insulation in the attic is the reason for a cool room in the house? I have caulked around windows and gaps in the exterior of the house already. What's next, ripping the walls apart to see what's inside those exterior walls? Thanks for any help here. Then I just have to figure out how to keep the darn squirrels out, and doing this all over again. ;)
