Bowed areas were left to gradually flatten on stiff
boards, and broken leads were re-soldered. Areas of lost
waterproofing compound were treated with the re-application between the lead flanges of linseed oil putty mixed
with carbon-black pigment, applied by hand. In their new
internal location the windows will no longer serve as a
weather shield. However, for added strength and stability,
it was essential to use this cement to prevent future
bowing. The original frames were professionally shotblasted to removal all traces of hazardous asbestos from
their original setting, and were re-patinated.
To illuminate the windows in their new internal location,
custom-made back-lit LED screens were created by
Applelec of Bradford, which can be fully calibrated. The
historic glass and the lighting units were fitted with 3mm
opal acrylic diffuser sheets between. The new installation
was designed to achieve a low-maintenance, low-cost
lighting system with adequate ventilation to ensure that
the glass remained cool and dry. Light levels and colour
temperature can be programmed, adjusted, and managed
using integrated controls to achieve a natural-looking
illumination in the new setting.
