I have a log cabin that we wish to do some remodeling on. To create some more interior volumn, we’d like to open up some of the ceilings and expose the existing pole rafters and 24″ wide roof boards. To acomplish this, I’d like to put the insulation above the existing sheathing. I see two ways to accomplish this: Over frame the roof and install batts or use rigid insulation. I’m favoring the second method because the rigid insulation doesn’t have condensation problems, is more efficient, more affordable, quicker to install and is less thick. What is stumping me, is the installation of the SIPs. Typically, the panels are installed and super long screws are run in from above into the frame. In my instance, the lodge poles are anything but straight so it’ll be very hard to hit them. It would be easier to run the screws into the existing sheathing, but I don’t want them to be exposed from below. I could try to use some drywall screws from below into the SIP skin, but I don’t know if this is a approved installation. Again, I’m also concerned about the visibility of the screw heads. Does anybody have any suggestions?

Greetings 1110d,
Providing the general location of the building will help posters convey more accurate advice as the subject matter involves heating/cooling insulation values and techniques.

You can be clever in you bore a hole large enough for the screw to go thru and up into the SIP then using a plug cutter make plugs to fit the holes.. If you are careful about grain orientation and use the right matching wood the plugs will all but disappear. Let the glue dry for 24 hours before you chisel them off and match the contour..
Pay particular attention to the edges going under the roof. Large potential for problems in those areas..
