Openable or non-openable windows?
All widows fall into two categories: openable and non-openable windows.
Non-openable windows are simple: they (surprise, surprise) don’t open. It’s just a frame with a piece of glass, containing no moving parts. They’re cheaper and reduce air filtration to almost nothing (and so are super energy efficient).
Openable widows are a bit more complicated in their designs. That’s because you have:
- Single-hung or double-hung windows: two panes in two different sashes. For single-hung windows, one of the panes slides, and the other is fixed. For double-hung windows, both windows move.
- Sliders – These are kind of like double-hung windows, but the sashes are horizontal (rather than vertical). The panes slide from left to right.
- Casement windows – these are also very popular, and use hinges. The sash is hinged on the side and – kind of like a door – it swings open.
- Awning and hopper windows – these windows are small-hinged and feature a large non-operating sash. Your awnings are hung at the top and swing open (typically outwards). Your hoppers are hinged at the open and also swing open (typically inwards)
Both openable and non-openable windows are an excellent choice. It just depends on what you think looks best in your home. Openable windows give the most choice as you can have them open or shut whereas though a non-openable window is always the shut, however it gives you the best view.
An excellent choice of glass, if you’re keen to maintain your privacy, is the one-way window. You can see outside your home, but nobody can see inside.
The most effective way to do this is installing a reflective film on your window, giving the outside of your window an appearance of a mirror during daylight so nobody can see inside. But at the same time, you’ll be able to look outside and enjoy the view.
