Need help! How to insulate when stud walls are already up
So I have been completely busy with work and left the basement planning up to my husband, who does not know that much about basement finishing. Now, not busy, I realize we have made a mistake. The studs are already up throughout the basement and this morning the electrician came to wire. We have not put foam insulation in yet :(
Obviously, we should have done that before the studs went up. What should we do now?? We can still buy the foam boards and cut them to fit behind the studs and then tape them to say 14" pieces between each stud? Or should we find another method of insulating (besides taking down the stud walls and starting over).
Thanks for any info you can provide!
