Abstract (en)
[origin: GB2429988A] A roof system comprises a lower support layer of composite insulating panels 2, a protective barrier layer 3 and an upper decorative layer 4 which may provide a roof garden. The composite panels 2 comprise a profiled internal sheet 5, a generally flat external sheet 6 and an insulating core (7 figures 2, 3 and 5) between the sheets. The panels 2 may be manufactured from steel with a core of foam to provide a mechanically strong roof structure supporting the decorative layer 4. The decorative layer 4 is preferably a planting medium suitable for vegetation such as grass or plants or may also include a decorative layer of stones, sand or gravel. The panels 2 are preferably protected by a root barrier membrane 11.
