This morning, we created a further set of glazing bars for clamping down the fourth edge along the bottom of each window in the Skylight. It is a 20mm wide and 4mm thick in a so-called feather edge style. We sliced up our supply of 7 lengths of 4metres strips, into 33 individual pieces, 10 were 1metre long, 21 were 800mm long and the final 2 were 600mm long, to fit the various width windows (33 of them!) around the whole Skylight. Each of these strips were then glued onto strips of rubber membrane so these aluminium pressure bars will not scratch or dig into the polycarbonate plastic window panes, especially when there is a temperature difference and the plastic expands and shrinks over the course of a day in different seasons.

While the glue was drying, we went outside to start fixing all the rubber gaskets to the skylight framework. We tackled the ridge beam, which also needed three stainless steel threaded rods fitted too, one at each end and one in the middle, to support the Bird Disruptor.

Tomorrow, we will cut up the rest of the rubber gasket into strips of 1280mm long (27 in total) and a further 4 strips of 1800mm long pieces (for the diagonal rafters). The final line of rubber sealing strips will be the outer rim, stop and starting at each rafter.
