unglazed window openings
Permanently open window apertures admitting light and views through a facade, with screens or no barrier.
Unglazed window openings are permanently open apertures in a facade which allow light and views into the interior. They can be screened, or totally free of any barrier.
A screen can cover the aperture without adding glazing. The opening remains a permanently open window aperture.
A glazed window temporarily opened for ventilation is a different case. No windows applies where the facade has no qualifying window apertures at all.
