Topic: Product & Installation Information / Install over wood subfloor

Hi there, I’m thinking of installing WarmlyYours over the wood subfloor of my new sunroom. I understand that installation over a cement slab will warm the slab somewhat and keep the heat; however, installing over wood would just dissipate heat through the wood, right?

Should there be some sort of thermal barrier over the wood before installing the mats and tile?

Thanks.
