When comparing European and American windows, you’ll notice some differences. First, with American models such as casement windows, you’ll crank not pull to open the window. While they offer some usability advantages, they don’t deliver the same functionality or energy efficiency found in tilt and turn windows. Because tilt and turn windows tilt open inwardly, they are easier to clean. Moreover, European windows deliver the highest levels of energy efficiency for residential windows, making them a smart choice if you want to reduce your home’s carbon footprint.
