I am the first to admit that I do not know very much about home insulation.  I live in an old house and it is not insulated properly.  I have read about different types of insulation, but I am more confused than ever.  I have no idea which type to purchase for my home.  I have read some pretty good reviews about Mineral Wool Insulation.  I like the fact that it is heat and fire resistant.  I am leaning in that direction.  The winter months are extremely cold where I live and I have to take action soon.  My utility bills were through the roof last year and I do not want to see a repeat of that.
