The insulation of the floor on the balcony or loggia should begin by processing its surface with mineral wool or foam. After you can start installing a warm floor. Only strictly electric warm floor is used on balconies, it is also a cable heating system. When installing such a floor, the electric cable is mounted more than the floor covering, only the thermostat necessary for switching the heating mode is left.
It is very important to put the thermal insulation surface to the floor before starting work. This is necessary so that all heat does not go down. The surface of the floor should be aligned. Using the cable, it will also be necessary to pour the entire surface of the floor with a special coating for its screed. After it dries, the floor of the loggia or balcony can be covered with tiles. If you decide to use the thermal film and mats in the work, it will be quite enough, only the adhesive mixture. Apply the screed in this case. Also, unlike the first method, here you can use any floor covering. Using a thermostat, you can easily change the heating intensity or completely turn off the heating.
