Do you want to change up the look of your windows by adding interior shutters? If so, you'll want to consider the following things before you make a purchasing decision.
The Frame Choices
There are a few types of frame options you have to pick from. Full shutters stretch from the top of the bottom of the window frame as a solid piece. Cafe shutters are split so that you just have shutters at the top or bottom of the window frame; these are frequently used in bathrooms, where you want to cover the bottom half of the window. Double-hung shutters have doors at the top and bottom of the divided shutters, so you can either open the top half or the bottom half, depending on how much light you want to bring into the room. No matter what style you get, you can then have divider rails installed so that you can control the shutters being open or closed on the top or bottom of them.
The Mount Choices
Interior shutters have a variety of ways that they can be mounted, with there being inside and outside mounts. An inside mount is set into the window frame so that it is flush with the molding, which works best for casement windows that can fit an inside mount. Outside mounts have their own framing around the window, which resembles the look of a casement window for those that do not have the space for an inside mount.
The Louver Choices
There are also options for the louvers in the interior shutters, which is the thickness of that bar that stretches across the window and controls how much light is let into the room. A large louver can give a room a grander feel to it, which is why many people pick bigger louvers for bigger rooms. For smaller rooms, like bedrooms and bathrooms, you'd want to go with a smaller louver that fits the size of the room.
You will also need to pick how you want the louvers to tilt. There is the option for them to face downward or upward, which depends on how you want to block the light coming into the room. You also have the option of a pull bar across the louvers to control how they open and close. A pull bar is not necessary, but it prevents the need to grab the actual louvers to close or open them.
