The invention discloses a thermal insulation door and a manufacturing method thereof, and belongs to the technical field of thermal insulation materials. The thermal insulation door solves the problemthat a thermal insulation material adopted in a building door body in the prior art is high in aperture ratio and water absorption, complex in process or high in cost. The thermal insulation door comprises a shell body and a thermal insulation layer located inside the shell body, wherein the thermal insulation layer comprises the components of, in parts by mass, 350-100 parts of foamed glass particles, 50-80 parts of cement, 6-8 parts of adhesives and 30-60 parts of water, wherein the foamed glass particles are of a composite structure and comprise porous balls and glass shells wrapping the porous balls, and the glass shells are continuously closed compact colored glaze state shells. The manufacturing method comprises the following steps that elastic layers are cushioned inside a groove of a lower shell body and
