Not caulking vertical seams on siding
I’m about to put up siding on a building enclosure that includes a WRB, taped XPS and furring strips. The siding will be a combination of lap wood siding (front) and ColorPlus Hardie Plank (the rest). All butt joints will be flashed. My question is limited to the seams in which the siding contacts vertical trim.
I am in agreement with Martin not to use caulking as it seems to cause more problems than it prevents (http://www.greenbuildingadvisor.com/community/forum/green-building-techn...)
1) Do I need to use some sort of flashing at these seams? If so what is the best practice?
2) Hardie bulletin (http://www.jameshardie.com/pdf/install/hardieplank-hz5.pdf) seems to indicate that these seams should be caulked. However from my read, if you painted the cut ends you would not need to caulk. The bulletin states: “Terminate non-factory cut edges into trim where possible, and caulk” but also says “DO NOT Caulk field butt joints on ColorPlus siding.” SO can I just paint the cut ends and not caulk?
