    Default Re: extending width of rafters for insulation

    Howdy 8' tall ceiling are you wanting to insulate the rafter bays ? or create a 2by6 ceiling below the ridge beam?
    Any an all of my comments are just my opinion and not to be confused with facts.

    You should be able to find blue Dowboard in a 2" thickness. It would get tacked up with a few nails (they sell washer-head nails for fastening the dowboard), tape the seams in the boards with Tyvek tape or something like it. Then keeping in mind where the rafters are, hang the drywall so it goes across the rafters. You may have to cut sheets so they break exactly on the rafters. The foam is both light and rigid and won't weigh down the drywall. You should be using 5/8" sheetrock for ceilings on 2' joist centers so it won't sag.
