Yes the lamination would be to lock the weave. In previous versions there was no weave. Weaving technically should make things weaker, but is necessary to have normal fabrics. The thread count looks low to me when it is easy to see the threads. It would not make a good canopy material like that. With a gain in weight to fill so large holes with coating or what every laminate.
Wait to see the new Duotone lightweight dacron. Not as light as the Aluula, but 'lower thread count' than conventional dacron.
OK. But again I am concerned with the lower thread count. In foil kites it leads to more porosity. This would affect the canopy on LEIs, but I wonder about the bladder as well. The fabric is less smooth and the gaps may increase stress. Overall I am really wondering about longevity, glue in general is known to be less reliable or unpredictable.
As for the adhesive tape - LEI canopy seams have always been relying on it. Without it a canopy will tear apart at the first loop or harder landidng, especially when new and crispy.
Well foil kites do not use it. I am aware of it being used say in repairs to help with alignment. I don't see it contributing much strength, other glues could but they all would seem to eventually deteriorate too much. Stitching is the most reliable join.
