Window Types
Awning windows
open outward from a top frame hinge. They are energy efficient, great for ventilation and can be kept open in rainy weather.
Bay and bow windows

Casement windows
open from a side frame hinge. They have a modern look and feel, and let in a lot of natural light.
Corner Windows
