A novel thermal insulation ceiling comprises a thermal insulation ceiling body. The thermal insulation ceiling body is connected with a thermal energy pipeline through a rivet, and the rivet is fixed on a fixed block of the thermal energy pipeline. The fixed block is welded with the rivet. A thermal insulation layer is arranged on the outer layer of the thermal insulation ceiling body, and a diatom ooze layer is arranged on the outer layer of the thermal insulation layer. The thermal energy pipeline is provided an inlet and an outlet. An internal thread, provided with a nut, is formed in the inlet of the thermal energy pipeline, and an external thread is formed in the outlet of the thermal energy pipeline. The novel thermal insulation ceiling has the beneficial effects of providing a function of improving the indoor air quality while taking full use of thermal energy to achieve uniform indoor heating, eliminating unpleasant smells and formaldehyde, being fire protective and flame retardant, reducing noise and insulating sound, and being incapable of blocking the pipeline.
