Sliding Barn Door Header - with exterior insulation

[John P.]

I have a somewhat unconventional construction going on right now. I've posted on it before. One thing I did not figure out ahead of time (my bad) was how to handle the sliding door header. I figured it would be easy to figure out once I got to it, but honestly, I don't know what to do now.

The description below describes my situation, but basically if anyone knows of any resources that I can use, I'd appreciate it.


Up to this point everything I've done has either relied on prescriptive tables or engineering reports, but this header is uncharted territory.

This is a simplified view from the inside:



And a view from outside:



The ugly repeating pattern is 1/2" OSB, pink is 2" of foam. An air/water/vapor barrier goes on top of the OSB:



I want to put 1 or 2" of foam between the header board and the structure, so that the thermal envelope is unbroken there. Additionally, I don't want a through-bolt - I would like to use structural screws or lags so no fasteners show on the inside. This view shows a side view:



Any ideas? Also, I would like to lower the door 12", but then the beam would only have a few attachment points.

The easiest would be to just build tall doors so the track could be mounted at the same location of the existing beam on the inside.  On my barn, I framed around the doors and windows with 2 inch thick nailers to match the thickness of the foam.  Just cut the foam to fit and add your choice of siding.






I used swing-out doors on mine.  However, if I had installed sliding doors, I would definitely add a sloped rain cover over the door track something like this:
