A sidelight is a narrow, typically fixed window installed alongside an entry door, adding natural light to the entryway and often visually widening the door’s overall presence, whether installed on one or both sides of the door depending on the specific design.
This architectural feature is particularly common on entry doors, contributing both functional light admission and a more substantial, visually impressive entrance appearance than a single door alone would achieve.
Because sidelights are positioned adjacent to a door, a location code identifies as hazardous given impact risk, they’re required to use safety glass, whether tempered or laminated, rather than ordinary annealed glass.
What Does a Sidelight Involve?
- A narrow, typically fixed window beside the entry door
- Safety glass required given proximity to the door
- Often decorative glazing patterns matching the door’s style
- Installation on one or both sides of the entry door
Why Are Sidelights Important?
Sidelights significantly enhance an entryway’s natural light and visual presence, often transforming a simple single door into a more substantial, architecturally impressive entrance feature that contributes meaningfully to a home’s curb appeal and interior foyer brightness. This visual and functional enhancement has made sidelights a popular addition to many entry door designs across various architectural styles.
Because code specifically requires safety glazing at this location given its proximity to a door and associated impact risk, any sidelight glass, whether original or replacement, needs to meet this safety standard rather than using ordinary glass that wouldn’t provide the same injury-reducing breakage characteristics. This attention to code compliance is a simple but important safeguard for any entry door project.
Sidelight vs. Door Transom
A sidelight is positioned alongside the door, adding width and light from the side. A door transom is positioned above the door, adding light from overhead, both serving complementary functions in enhancing an entryway’s overall light and visual impact.
