The Glass Wall is a background wall which is crafted out of Glass.
Glass Walls will allow sunlight into a house during the Day, but it is still advised to keep Torches inside the house as well, as sunlight does not count as a Light Source.

The Glass Walls are seen in the background, being used as nice windows.
