Editing Window (section)

=== Other construction details ===

Many windows have movable [[window covering]]s such as [[blinds]] or [[curtain]]s to keep out light, provide additional insulation, or ensure privacy.
Windows allow natural light to enter, but too much can have negative effects such as glare and heat gain. Additionally, while windows let the user see outside, there must be a way to maintain privacy on in the inside.<ref name="Design Evaluation Project">Howell, Sandra C. (1976).
