Abstract:
A roofing laminate includes a roofing membrane, preferably a white roofing membrane, which is covered with a protective sheet. The protective sheet is tinted so that it has a coloration distinguishable from the roofing. The roofing laminate is applied to a roof surface and the release liner protects the outer surface of the membrane from scrapes and dirt during installation. Once the roof is installed the protective sheets are removed from all of the membrane sheets, exposing a clean surface.
Abstract:
A low profile flexible photovoltaic cell system (10), which is particularly suitable for use on sloped surfaces such as hills, landfills, and the like, includes a plurality of photovoltaic cells (28) adhered to a flexible membrane (22). The cells (28) are aligned so that the electrical wiring (48, 50) for each cell is at an upper edge of the membrane as it would be located on a sloped surface. A flexible flap (60), preferably made out of the same flexible membrane, is bonded to the flexible membrane immediately above the top edges of the aligned photovoltaic cells (28). The flap (60) extends downwardly and covers the electrical connections (42,44) of the photovoltaic cells (28). The free end (64) of the flap (60) is, in turn, fixed to the membrane (22) fastened to areas between adjacent photovoltaic cells using a hook and tile type fastener (66 and 68), or a strap, or other type of connector. This protects the electrical connections of the photovoltaic cells from the elements, in particular, water, snow and ice, but can be easily opened for inspection or repair.
