cavity closer above arched window
 

What cavity closing detail might be required above an arched window for
current building regs? There would be no structural arch, a lintel
would be above. Some type of curved insulated closer ?
Thanks,
Simon.

How about closing it as if it was a rectangular window ie. above the level of
the arch.
