  • Installing insulation

    Is there any dywall problem to face stapling kraft paper insulation to joists? I'm building workshop for myself and doing all the work, including insulation. Directions state to face staple, but do you pro hangers perfer side stapled or what. It's a catherdral attic area, with R-30c. Thanks for any insight.

    It just depends on whether you want to use glue. If you use glue, you have to side staple.

      INSULATION STAPLED ON THE FACE MAKES ATTACHING THE DRYWALL VERY DIFFICULT AND STILL THERE IS A RISK OF SCREW POPS. STAPLE ON THE INSIDE ESPECIALLY ON CEILINGS WHERE IN ADDITION TO THE PAPER MAKING IT DIFFICULT TO FASTEN THE INSULATION WILL SAG BELOW THE JOISTS AND PUT ADDED PRESURE ON THE FASTENERS.

        I have always stapled to the face to maintain a continuous vapor barrier.

        Also, on cathedral ceilings we have been installing 1" DOW foam board under the drywall for additional insulation. It's difficult to hang the drywall with 2 1/2" screws, but it allows for a nice flat surface as the foam board tends to average out the framing.
