The support structure 1 comprises a first outer elongate member 2, which is made from a low thermally conductive material, is mechanically coupled to a second inner elongate member 3. In use the elongate members are arranged such that only the outer inember is exposed to the atmosphere, and the second member is protected from the atmosphere. The inner member may have an L shaped cross section arranged so that it is mechanically coupled in a back to back manner with the outer member. The outer member may be made from a composite material, for example extruded fibre reinforced polymer or plastic which is reinforced with carbon fibre or glass fibres. The inner member may be made from a metal such as steel. The elongate support structure may be a lintel. |
