While it is true that sudden changes in temperature can damage your wooden floor, there ARE real hardwood floors that are designed to withstand through radiant heat.
I don't think it's possible for a solid plank of wood, but many engineered floors offer this option.
Engineered floors have a ~7 layer plywood/poplar base with a 2-3mm layer of real hardwood on top.
If you are looking for a domestic product, we have a few floors that are designed for radiant heat: Engineered Flooring -Domestic Species
This effect can only be reproduced on domestic species... we still cannot guarantee an exotic floor such as Jatoba, Cumaru or Doussie to withstand radiant heating.
As for laminate wood flooring... It won't work simply because the membrane on which a floating floor is laid on will melt from the heat.
Engineered wood floor is the most recommended answer for radiant heat.
