A plastic extrusion (6) for the lower edge of a roller blind housing (2) made from an inner body (8) of an insulating material, e.g. expanded polystyrene, and outer panels (9) of cement and wood fibres, has a main section (16) with walls (19, 22, 23) enclosing the lower edge of the housing, and a covering section (17) which receives a panel (7). The panel (7) covers part of the housing's lower open end, leaving an aperture (15) for the blind (1) to pass through. The extrusion (6) is made from a plastic material, e.g. PVC, and its covering section (17) can be coloured to match that of the lower panel and the blind.
