I dont see how this makes sence, if anything you should lay down reflectix then put flexwatt ontop of the reflectix so that heat doesnt radiate down, but all goes up to the bottom of the tub.

get what im sayin? if im wrong, sorry lemme in on the secret.
Your bottom example is correct in how this rack was build.

Tub
Metal Sheeting (helps to hold the heat longer and disperses is over a larger more consistant range)
Flexwatt
Reflectix (furtherest from the tub - acts to reflect any heat back toward the tub which allows the flex to work more effeciently)

Hope this clarifies the setup for you.
