The most important parameter of an aluminium window
Tilt-and-turn windows won’t be for everyone. The more complex gearing means window frames are thicker than side-hung or top-hung versions. The main advantage of tilt-and-turn is that they come in significantly larger sizes. In fact, it’s possible to get tilt-and-turn windows that are virtually the size of a door. As a result, they’re ideal for windows leading to a flat roof or a Juliet balcony.
