Anyone here using Sunboard panels? Thoughts?

After doing a lot more reading I have come to the conclusion that radiant ceilings might be a better option for part of my retrofit versus putting down extruded plates below and above the subfloor in my house. I have looked at sunboard and their product is not much more cost than aluminum plates and the time saved would be worth it. Any thoughts on sunboard? Warmboard is too thick for my application.

Also, my attic space will be airsealed with closed cell foamed being sprayed on the bottom of the roof sheathing. Will I need any additional insulation on the top of the ceilings if I were to use sunboard panels on the bottom of the ceilings joists over the bedrooms?

Will the 3/8 pex panel put out significantly less heat than a 1/2pex panel? I would prefer to use the 3/8 to keep my flooring heights relatively close.

Thank you for the help

    Messana makes a great radiant heating and cooling ceiling system. They have the controls, HRV, Humidity sensors to make it all happen. They have the complete package. There system can heat up a space just as fast as scorched air can. They have a very fast response time. Where are you located? I might be able to help you with that.

    Use Sunboard for years now . Good product , good service , good people . 3/8" will more than likely be quite sufficient as opposed to 1/2" . Make sure you don't get fooled by the names and use the Sunborad Silver , silver has graphite / aluminum through the grooves as opposed to sliced with less conduction .
    You didn't get what you didn't pay for and it will never be what you thought it would .

    How do you guys feel about having a "hot roof" with radiant floors rather than insulation being directly on top of the ceilings? I am planning to closed cell foam the entire bottom of the roof sheathing so that I can possibly place a manifold and air handler into the conditioned attic.

    Low pitch (4/12) roof, bottom of ridge beam is roughly 5ft above ceilings.
