RJ, I checked out that site, thanks!
It does seem like there are some "advanced" forms of PVC or composite decking that don't heat up as much.
Lighter colors of course will heat up less than dark ones.
I also found this site when googling.

Look for the AZEK options.
Half the deck is now somewhat shaded by a crepe myrtle, and the other half will be covered with a new canopy (the old one disintegrated 2 years ago). That helps, but the wood boards are still sometimes too hot for bare feet, and regular composite would be much worse.
It doesn't look like Trex has anything comparable to those other 2 brands that claim to be cooler underfoot. Newer Trex does have a nicer look (woodgrain) than the original product.
Nothing to do with the original question, but I'm moving the old (still very sturdy) canopy frame to the side patio. It no longer has a dome-shape on top, but I think I can put shade cloth just straight across from one side to the other. I'm thinking A.M. Leonard should have something I can use for that, but I'd welcome suggestions.
Thanks!
