An outside mount is required when the window has no reveal or recess. All shutters are mounted within a frame. Where you have no recess your shutter frame will be surface mounted onto the actual window frame or surround. The most typical type of window having outside mounted shutters would be a sash window. If you are still unsure if you require an outside mount and you can answer 'yes' to the following, then you must go for an outside mount.
- Is your recess less than 40mm?
- Do your windows open inwards?
Use a steel tape measure
- Measure from left to right across the window remembering to include 33mm left and right, to allow the shutter frame to sit flat on your window surround.
- Measure the window top to bottom, remembering to include 33mm for the frame at the top. The bottom of the frame will sit flat on your window sill.
- To confirm, the total width and drop that you convey to us will include area on the window where the shutter frame will be mounted.

How to measure an outside mount
The green lines above show where your shutter frames will be mounted. You need to measure as indicated by the black arrows. Remember – the dimension you give to us includes the frame itself.
If
ordering full height panels with a mid rail please measure to the blue
line to ensure the mid point of the mid rail is at the mid point of the
window transom.
If ordering café style or tier on tier shutters
measure to the red line (the lower panels will then cover the window
transom). To measure please refer to page ‘How to Measure an Outside
Mount Window’ and use the templates supplied. Below is an example of
how tier on tier shutters would look when installed.
Checking for Obstructions
Before measuring, look for any obstructions on the window. You need to make sure that you avoid the possibility of the slats tilting open and hitting any obstacles such as handles or phone junction box.
We advise that phone points, if they sit in the way of the shutter frame, should be moved. This is generally the case with 3 section Victorian sash windows. However for handles, especially on UPVC windows, it is not easy to change these and you therefore need to ensure you measure correctly to accommodate the handles.
- Measure how far into the room the handles protrude.
- Depending on the slat size you choose check if you will have enough clearance or if you need to pull the frame forward.
- You can order a deeper frame if you choose. For example a 4032 (67mm deep) frame for a 47mm slat. We can also custom make a non standard depth frame for additional cost.
