Sliding glass door
In architecture and construction, a sliding glass door (also patio door or doorwall) is a type of sliding door made predominantly from glass, that is situated in an external wall to provide egress and light. The doors can give access to a backyard or patio while providing a pleasant view, and when not fully covered can be a source of passive daylighting. Like a window, when open it also provides fresh air and copious natural light. It is considered a single unit consisting of two or more panel sections, some or all being mobile to slide open.
Roof lantern
A roof lantern is a daylighting architectural element. Architectural lanterns are part of a larger roof and provide natural light into the space or room below. In contemporary use it is an architectural skylight structure. A lantern roof will generally mean just the roof of a lantern structure in the West, but has a special meaning in Indian architecture (mostly Buddhist, and stretching into Central Asia and eastern China), where it means a dome-like roof raised by sets of four straight beams placed above each other, "arranged in diminishing squares", and rotated with each set.
