What is the structure (order of layers) of underfloor heating system?
Mid terrace house built in the 60's, the floor is stripped down to concrete. We would like to install underfloor heating... Have heard of these underfloor heating systems as a dry construction system. But essentially we have the following question:
— What is the structure of the underlayment? Pouring – insulation – underfloor heating – screed – floor covering?
— Why does the underfloor heating have to be under the screed? Will it also work over the screed?
— Is there anything else important to consider?
The underfloor heating should be under the screed because it has many advantages: the screed protects the heating, distributes the heat, and preserves it
Insulation can go under the underfloor heating system, but you can also use the basement ceiling as an alternative (then you won't lose room height).
