We are going to be redoing our basement which was done in the 60's and very cold. We have been told to apply Tyvek or tar paper to the walls, stud, then vapour barrier and drywall. We plan on using fiberglass batt insulation because of costs (we are retired and limited income). We would love to do the spray foam and not have to worry about all the vapour barrier and such but we are out of budget - Styrofoams seems like a lot of work by the time you have to cut each piece.
We are going to get some prices by contractors but want to do some work ourselves to keep costs down so of course the behind the scene work is what we want to do - i.e. studding (16 inch on centre and insulating and maybe installing the drywall but not taping and finishing). If we use tar paper, do we just overlap it or do we tape it much like you do the seams of Tyvek? Do we go right to the floor with the paper or, like with the insulation, do we keep it a foot off the ground? Any help, suggestions are greatly appreciated.
