If your basement windows are wooden, they will rot or warp over time. Metal basement windows tend to leak and rust because basement windows are close to the damp ground.
Types of Basement Windows
Awning basement windows are hinged and open with a crank handle and screens on the outside of the house. Hopper basement windows are hinged at the bottom of the window and open to the inside of the basement. They also have screens on the outside of the house. Horizontal slider basement windows open side to side with screens on either the inside or the outside of the house.
When choosing basement windows keep in mind that hinged windows are better at stopping drafts and reducing water leakage. Hinged basement windows have a tighter seal because the window is pressed against the window frame when it is closed.
