My first post.... Glad I found this forum, seems like a lot of valuable info here. I am hoping to get some feedback on the issue I have found in my house while redoing our dining room. The electrical issues that can be seen in the photo's are one of the reasons I pulled the drywall to begin with and are being corrected. My dilemma at the moment is how to properly insulate this area of the house. The roof/ceiling is 2x4 construction and pretty much "Non Vented" (to the outside of the house anyway). Whoever re drywalled this room at sometime before I owned the house installed FG insulation in some places and none in others. It was poorly done. The drywall is chalky and feels dried out. I am going to pull the rest down and redo it all but my dilemma lies in how to insulate this area the right way. In the first photo it shows the lower side of the room. The wall joins the dining room and our garage... Sooo obviously not vents here. In the second photo, It shows the higher side ( with some FG ins. exposed ) which shares the wall with out kitchen. There is no blocking and it is open to our attic space. Then an overall shot of the ceiling. Last is the adjacent room that is also vaulted. This has been poorly insulated as well (from the inside and covered with bead board) and is going to get redone. This room has 4x6 beams, T&G for the ceiling. http://craftwerks.smugmug.com/Other/Random/i-VhDzPjF/0/M/IMG1223-M.jpg My plans are to have it insulated from the outside when we redo our roof so that we can leave the beams and T&G exposed. I am in Southern California FYI. Any input would be much appreciated! Thanks in advance!
