Obstructions could be inward opening windows or fly screens, which may not be accessible if you inside mount your shutter. Other obstructions, such as window winders, handles, locks, keys, alarm boxes are fine - as long as you have enough clearance between the end of your obstruction to the end of the recess.
Even with a deep recess, your window may have obstructions that could get in the way of inside mounting your shutters; but there are ways around this!
WHAT IS A SHUTTER FRAME?
Whether you're inside or outside mounting, shutters generally need to sit inside a frame (there are some exceptions to this rule). The frame will be designed to fit the style and size of your window. Once you have mounted your frame, the shutters will hinge inside the frame.
INSIDE VS OUTSIDE MOUNT?
There are some notable differences between frame types. We offer three types of frames; one for outside mounting, two for inside mounting:
A (different) L frame for outside mount.
Inside mount (Recess Fit) shutters sit inside the window recess and are usually fitted in line with the wall. Outside mount (Face Fit) shutters are fitted onto the architrave (window frame), on the outside of the window. Both mounting options look great! However, some people prefer inside mounting because the shutters won't project into the room. Inside mounting also results in a slightly smaller shutter, saving you money.
HOW DO I KNOW IF I SHOULD ORDER AN INSIDE OR OUTSIDE MOUNT?
If you have a recess with at least 70mm of unobstructed clearance (e.g. free of window winders, locks, handles etc), you will most likely be able to inside mount your shutter.
