Osiris Twinsash Windows

TwinSash Windows are super cool because they can do a lot of different things! They are made so that people who make windows and people who buy windows can both be happy. You can have a regular window that opens like a door, and also have a screen to keep bugs out. Plus, you can add a grill or blinds to make it even more secure and private. There's even a special kind of window that has little slats in it, and it still has a screen too! The people who make these windows can use fewer pieces to make them, which is good for them, and the people who buy them can choose from lots of different options.
