I'd like to add my questions to this discussion since it is related.
I own a semi flat roof home with open beam ceiling. On top of the rafters sit 2" insulboards with tar and gravel on top.
My ultimate plan is to insulate and then to cover the ceilings with sheet rock and install recessed LED lights.
The rafters show different amounts of sag which causes a problem putting up sheet rock.
The area between the rafters above the wall is poorly insulated. I saw a few areas where I can even look into the house from the ouside through gaps in this area (See area on attached Pic 1 and Pic 2).
I thought about putting up rows of 2x4's perpendicular to the rafters at 16 " spacing. This would tie all the rafters together and would form a solid, level base for sheet rock.
Question 1: Is this a sound solution to counter the different amounts of sag?
Next I read about "vapor barriers vs vent" topic and the condensation issues this could generate of not done right.
Question 2: Looking at the pictures I attached to this post, what would be best practice to get this done with a good (best?) rate of insulation? Could you explain what I need to watch out for in my case to make sure no problems arise?
Thanks a lot for all your support. This is a great forum and I just signed up and this is my first post!!
