Drywall above the Windows

The interior walls, made of light straw clay (LSC), will be covered in clay plaster.  For the finish coat, I've decided to use an American Clay, pigmented product.  This should make for an easy and predictable finish coat.  I really like how informative their website is, complete with detailed videos.  Check them out at americanclay.com.

I've mentally tried out various techniques to deal with the areas above the windows and for the window sills.

This photo shows the plastic above the windows, which holds in the cellulose insulation.  This needs to be covered before I can plaster it.  Since American Clay can be applied over drywall, I decided that would be a relatively easy way to create a uniform finish coat, with a consistent look over both the LSC and the drywall.

Above the kitchen window, the drywall (and later, the finished plaster) gets notched for the I-beams, which are exposed.

This is a test section of ceiling showing the brown beams and off-white ribbed panels.

Above the closet, the beam (still unpainted here) runs along the top of the drywall and marks the top edge of the clay plaster.  The off-white panels will sit on top of this beam.

This shows the south windows.
