Vim: Skip quickfix buffer when cycling through windows

A common pattern when I edit files in vim is to have two buffers open using :sb, and cycle between them using C-w C-w. I tend to avoid having more two windows open because then the cognitive (and number of keystrokes) overhead of switching becomes higher.

I recently started using the quickfix functionality provided by :make, and now I have a dilemma. You see, the quickfix window constitutes another window: so now if I am mashing C-w C-w I have to cycle through three buffers, one of which I don't actually want to cycle into (usually). So, is there a way to make the buffer cycling commands skip qf windows?

General suggestions on how to improve my vim workflow here would also be appreciated.
