hi, i am demoing my bathroom in my 50 year old house... do I need to
insulate the walls before the sheetrock goes in? or is this just for

You will want to insulate exterior walls (meaning the other side of
the wall is the outside of the house) for sure, with a proper vapor
barrier. Interior walls it's your choice. Regular insulation will
help a little with blocking sound, ll HTH,

years old.. should i remove that and install new one? i imagine so .
thanks

Yeah, pull it out, it will be about R2 or less.
