Attic HVAC Working!

I had a 2 zoned system upstairs with a controller that can support 4.  So I tapped into the existing system and added a 3rd zone.

First I added the new trunk with a damper.

And tapped into the air return:

And set the distribution box above the room with 6 lines coming out of it (2 on each side).  Tested and everything works perfect!

Attic Insulation Finished

That's a hell of a lot of insulation!  All exterior walls are 2x6 or more, and have the equivalent of R-21 or higher (some places I doubled up R-13 to fit the wall cavity).

Attic Laying Bathroom Tile

Bathroom tile laid and glued down.  Waiting to do grout until after drywall is complete.
