Slide 5: Engineered Subfloor


Radiant Panel Association

An engineered, load bearing board takes the place of the structural subfloor. It has a laminated layer of aluminum and a channel to accept tubing. Hardwood floors can be nailed directly to the subfloor plates or carpet and pad placed over the plates. It is also possible to nail a second subfloor over the plates for a smoother finish for vinyl areas. A cement board is used when tile or stone is to be installed. Particle board is not recommended as a subfloor.
