Why are American windows different?

Generally, the more panes of glass used, the better insulating properties a window will have. Double-pane windows are commonly found in American homes. These provide a single layer of climate and noise insulation between the outdoors and a home's interior.

Why do European windows open inwards?

The vent suddenly tilts inwards, held by the hinges the bottom corners. That is possible because of an ingenious design: One of the hinges on the lower corner operates in two directions, supporting both tilt and turn.

Are European windows better than American?

European windows are better resistant to condensation which reduces the energy consumption especially, in colder climates. While most North American windows use double pane windows, European windows either have triple panes or even quadruple panes along with integrated blinds.

Why double hung windows?

If you have more room to reach both the top and bottom sashes, a double-hung window is a great option. Because double-hung windows are able to tilt in toward the home for cleaning, they're the perfect fit for rooms on the second story of your home, or where cleaning is difficult outside.
