The perimeter of
each skylight is made of an aluminum frame, to which the 3-layer cushions are
attached. In this configuration, these are mostly made from the following
materials: 200-micron screen-printed top layer with white hexagons, 250-micron
transparent flat middle layer and 150-micron transparent bottom layer.
The intersection between the aluminum frames and the roof is finished with an inner aluminum sheet that supports 50 mm of thermal insulation, with a top finish of RAL 9010 lacquered sheet flashing to match the aluminum frame, creating a monochromatic white finish between the ETFE screen printing, aluminium frames, sheet flashing and PVC waterproofing of the roof.
