Glazed doors – doors with a glass window or glass windows – allow light to pass through the door when it is closed.
Most of these doors have obscure glass which allows light in but also offers a degree of privacy.
A few (not many) are clear glazed.
A few are available with leaded glass.
Most are double glazed but there are a few that are supplied single glazed.
All glass in these doors is toughened, for safety and for strength.
