Help choosing radiant panel system
Hello and thank you for this great forum. I have been reading posts and trying to decide between Sunboard and Warmboard (both S and R) for our second story addition (new build) and existing first story (remodel), roughly 1200sq ft on each floor. I'm north of Seattle so it does get cold, but not very cold for very long. I was hoping you might be willing to give me some additional insights to help in my decision.
Our initial quote from Sunboard was for the "gold" version. I've seen Sunboard generally recommended on here and it is a lot more budget friendly than warmboard. However, I read in a helpful post "Do not be fooled by Warmboard's cherry picked comparison videos , such as their Warmboard / Sunboard comparison. Although they used a Sunboard product that was unfortunately named " Gold" which many would take as being the best , it is not . Sunboard Gold is a panel that does not have the aluminum or graphite coating through the groove as Warmboard does have . .... Sunboard Silver is in fact a through the groove coating application and WILL outperform the Warmboard products . Ask me how I know . If you are seriously considering WB for your project I urge you to look at Sunboard ."
I will inquire about the Sunboard silver, but I suppose my question is whether there is a clear benefit to WB that would make this a preferred option, or if it is just as, or nearly as good to go with a more budget friendly option, (especially if SB silver is similarly priced to gold)? WB has great customer support which would come in handy for my contractor who has worked with neither SB or WB.
I know there are other similar products available and I have chosen to avoid those with built in foam insulation as they contain added chemical flame retardants which I'd like to avoid.
Does anyone find that one is a better performer in the long term? Thank you so much for any advice and for all the advice I've already read! Beth
