(________) tub
======== reflectix
----------- flexwatt

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.
I believe the steel around the flexwatt strips is to help maintain heat better. A breeze will cause bare flexwatt to cool down very quickly. Wrap it in steel and the breeze also has to cool down the steel which maintains the heat longer. Basically it makes your thermostat work less!
