63. Hot air plant in roof.
This is the ducting for supplying hot air to the underside of the ceiling to prevent condensation dripping – potentially drips woulf disrupt the formation on the wire. I think this is a view south from memory of a couple of excursions into the roof when we installed insulation (some sort of shredded fibre material) in the early ’80s. The narrow walkway down the centre is visible, and was all that was present in the ’80s. The planking under the duct pieces is probably temporary during the installation, it was not present later. Access to the lamps in the ceiling was quite precarious I recall, the electricians had to inch their way out along the roof trusses to reach the lamp housings.
