Hi all,

i am installing Anderson casemnet windows on a garden shed. I know its not a big deal, but I am curious, whats the proper way to flash the windows? the casemenats have fins on the outisde that are nailed to the exterior sheating.

Now when I flash, do i put the flashing just surrounding the rough opening? or do i put the flashing in the rough opening and carry it under the fin of the casemnet? or do i put the window in first, then install all the flashing surrounding the window on top of the fin?

i plan on putting vinyl siding over, not sure if it make s a difference.

Also, what kind of flashing do you all recommend?

thanks a bunch!
