pvc hvac air distribution

Several years ago I saw examples of using 4" or so PVC to distribute hvac. Easily installed, many zones, even temps throughout, great for retrofit for old houses. Any help would be appreciated

The 4 inch ducting would usually be used in the high velocity type of system.
Mostly the 4 inch insulated flex ducting is used for the branch lines.
Using the insulated flex is easier and probably cheaper than using PVC.

Anyone got any info or links on using 4" PVC for this, interesting.
