Re: Home remodeling insulation question?
No, the insulation will do no harm. It will act as a sound dampening agent, which is a plus, particularly if you've got kids.
Another thing to do is DO NOT attach the ceiling joists to the new floor trusses. You want to keep them mechanically independent so as not to transfer sound from the floor above. I've done a couple of 2nd story additions and we set the floor joists between the ceiling joists specifically for this purpose.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
