What Is a Top Hung Window?
Top hung windows open from the bottom and are hinged at the top. You open them outward, which lets air in while keeping rain out.
They’re often used in homes, lofts, and commercial buildings. They’re also good when you need ventilation but don’t want the window to open into the room.
Key Benefits of Top Hung Windows
-
Ventilation: They let in fresh air without taking up space inside.
-
Unobstructed Views: You get a clear view through the glass, even when open.
-
Saves Space: They’re a good option above furniture or counters.
-
Weather Protection: Rain doesn’t come in easily when they’re open.
-
Versatile: They suit a range of building types.
