INAX has come up with some tiles that are “not cool.” The “Thermo Tiles” feature bazillions of microscopic air bubbles inside, reducing their heat conductivity. It seemed to me that reducing heat conductivity would be a bad thing when you wanted something to be warm, but the problem apparently isn’t in the tiles themselves. It’s with your feet; reducing heat conductivity allows your feet to retain heat that would normally escape.
Don’t expect to see/feel these outside of Japan anytime soon. Just in case you happen to live there, though, prices start from 12,600 yen per square meter.
