Flair vents

[harshl]

As someone who works in energy efficiency on both a residential and commercial scale I can't recommend these devices. Ductwork is specifically designed. Well at least it should be....... If you close a register you create imbalances throughout the system. The only safe way to have the resolution of controlling one room is to have that room on its own zone.

I know this thread is very old, and this may have been true at the time, however, I think it is worth mentioning that every Flair register/vent as well as the pucks, have back pressure sensors in them in order to help protect against this very thing so it doesn't close to many vents.

Looking into these myself and Flair looks like the best post construction option from my limited research so far.
