Should you insulate under the floor warming system?

In most cases, the insulation that is already in your floor will be adequate. If there is no insulation under your frame floor, we do recommend adding it.For Concrete floors, always recommend Cork insulation. Concrete slabs absorb part of the heat generated by the floor warming system so less heat is transferred to the flooring. Heat always moves toward colder surfaces, so it goes both up & down when the floor warming system is in direct contact with a slab. But, adding a simple layer of cork between the slab & floor heating provides a "thermal break" reducing the flow of heat into the slab and allowing MORE HEAT transfer into the flooring. Installing insulation on top of slab translates into more heat, faster response times and less energy used; a wise investment. There are a few other insulation materials available, but Cork is the best choice, since it is a natural product and a renewable resource, unlike other insulating products.
