After all of the walls are up, prior to setting 
your top plate, check and plumb the alignment

Apply a 3/8” diameter bead of Premier Mastic 
down the center and along each edge of the 
wall panel recess.  Set the top plate and nail it

and cripple, apply Premier Mastic and nail 
them together.  Slide the pieces into the panel 
recess.  Next, install the panel that sits below 
the window.  Put your trimmer and cripple into
