A skylight dome assembly comprises at least one dome-shaped shell 2 and a connecting profile 4 for connecting the shells to the upstand 5. The connecting profile 4 has a welded joint 6, preferably extending the whole length of the profile and preferably ultrasonically welded. The welded joint 6 may be formed as a pair of parallel welds. The connecting profile may be S-shaped and may have a clamping lip 7 to retain further shell 3. |
