3L heat insulation roof with solar capillary top plate radiant heating system

The invention discloses a 3L heat insulation roof with a solar capillary top plate radiant heating system. The 3L heat insulation roof comprises a radiation blocking layer, a convection blocking layer, a conduction blocking layer and a solar capillary; the conduction blocking layer, the convection blocking layer and the radiation blocking layer are sequentially arranged from top to bottom, and the solar capillary is arranged below the radiation blocking layer. By sequentially arranging the radiation blocking layer, the convection blocking layer and the conduction blocking layer on the solar capillary, in other words, the 3L heat insulation design is achieved, heat comfort temperature in a room reaches 21 DEG C, in a comparison system without 3L heat insulation design, room temperature is only 15 DEG C, and the 3L heat insulation roof with the solar capillary top plate radiant heating system is better in heat preserving effect.
