Today is a very exciting day for us. We are installing pex in the floor for heating bus’s floors. I would love to have this feature on the cold winter day in my future home. The process of installation is pretty easy. First, create tracks in the floor’s foam insulation (that creates a lot of sticky flying little pieces), then place pex in these tranches, then cover it with the aluminum thin plates for the better conduction of the heat in the floor, then cover by the plywood and, the subfloor is done!
