What are Dormers? | Building Construction
Eyebrow dormer is also known as the roof eyebrow since it resembles an actual human eyebrow. It is curved in shaped with a window in between with a fixed or operable glass.
Eyebrow dormer is a mixture of aesthetics and functions.
Aesthetically, it breaks the monotony of an angular or sloping roof.
And we are to assess it functionally, it serves as ventilator for the top floor spaces which would otherwise get heated up.
It does require skilled labour for construction but are efficient in their functioning.
Hipped dormers and eyebrow dormers serve a similar purpose with respect to aesthetics and functionality. The only difference between the two is the shape of the dormers. Hipped dormers have three sloping roof panels that do not allow the snow getting collected on the roofs.
