I really need to update the insulation to my basementWhat is there has been there for almost 30 yearsCan I tack up new insulation right over the old or would it be best to remove the old and just go with newAlso the old is R11 should I use the same or is there something better to use.
I just answered your last question.
you first get iron you pour salt water on it (speeds up process) and you waitIt's simple!
If you decide to add the insulation over the old, slice through the vapor barrier on the old with a utility knife here and thereYour new insulation will have a vapor barrier on it and you don't want twoGood advice to ask questions at the home improvement store.
