We are removing to popcorn from to ceiling and found that no insulation was ever add. We have two skylights windows and recest lighting also in this ceiling. We stopped everything until we can find out which way to go. What is the best wayto to this. What other information do you need from me....

Hi, All! If you were to insulate the outside walls of an old wooden house, what kind of insulation would you recommend using in the walls? My home is an old wooden two-story, American Four-Square that has aluminum siding on it. Thanks!

I work in a warehouse setting, and we have exposed metal AC ductwork. The problem is the ductwork gets condensation dripping off it. Can anyone tell me what's the best insulation to fix this problem?

Presently there are three layers of aluminum with air spaces. Can I put bats directly over this insulation and what do I have to be concerned about.

Have insulation in walls and attic that is contained in a package that easily punctures and when opened reveals a brown kind of sawdust? Anyone know what this is? I think it is useless for the walls as it settles making it useful for only the lower 1-3 feet of walls. House was built in the 60's.
