Abstract
Abstract A heating panel is provided with a solution acting as a thermal insulation layer (3) injected into a space within an outer shell structural member (8) of a hollow flat board structure. The interior of the outer shell structural member (8) is provided with a buffer plate (13) or a flow guide plate (20) in contact with the injected solution which regulates the direction of flow of the injected solution, thereby making it possible to prevent the high-pressure injected solution coming into contact with fixing elements (6) provided within the outer shell structural member (8) and connectors (1 B) of the outer shell structural member (8). Thus it is possible to prevent any unnecessary movement of the fixing elements (6) and any deformation or damage to the connectors of the outer shell structural member (8).
