You can buy Perfect Fit Shutters for windows up to 2250mm wide. However, the maximum width of a single panel is 750mm. Windows above 750mm wide, will be split into multiple equal sized panels, as explained below.
- Up to 750mm wide - 1 shutter panel
- Up to 1500mm wide - 2 equally sized shutter panels.
- Up to 2250mm wide - 3 equally sized shutter panels.
For example for a glass width of 1800mm, you will receive 3 shutter panels, each at 600mm wide. These will be installed side-by-side.

Measuring for Perfect Fit Shutters is really straight forwards. You will need to measure the visible glass size of each window pane at which you would like to install the Perfect Fit Shutter.  Follow the simple step-by-step instructions in our video below. Please also read the notes below:

- Where your window/door is has multiple panes of glass, you will need to measure the visible glass size of each glass pane individually.
- Whilst measuring, you should check that you have no window/door parts such as vents / opening bars within 23mm of the edges of the glass. Each shutter will overlap the visible glass size by 23mm on each side, as well as at the top and bottom. Window handles can be accommodated with handle packers or rebates. If you are installing to a door, please check that the door handle unit is no closer then 23mm from the edge of the glass.
- Perfect Fit Shutters are not suitable for doors or windows with sliding panels due to the amount the shutter projects (30mm) from the window/door frame.
- You should also consider this 30mm projection when ordering the Perfect Fit Shutters for doors which fold and stack, since the projection will prevent the door/window from stacking fully.

Perfect Fit Shutters overlap the visible glass of the window by 23mm each side and top and bottom. Trickle vents are usually positioned at the top of the window frame. If the trickle vent or any level used to operate the vent is within 23mm of the visible glass, then Perfect Fit Shutters will not work with your window. If you are unsure please contact [email protected]. We are happy to review any photos or videos of your window to assist with your decision.

Yes, you can still have Perfect Fit Shutters if your window is an opening pane and has a handle. When ordering your shutter you will be asked for the position of your handle - left hand, right hand or bottom. 

You also need to provide the measurement your handle. You will need to follow these steps:

1) Open the handle to expose the window handle base plate.
2) Along the side of the glass where the handle is positioned, measure from the edge of the visible glass to the centre of the base plate of the handle.

If the handle is located at the bottom of the window, please measure from the left-hand edge of the glass to the middle of the handle base plate. For windows with a handle on either the right or left-hand side, please measure from the bottom edge of the glass to the middle of the base plate of the handle.

In most cases, we will supply your shutters with a rebate (cut out) at the position of the handle to allow the handle to turn.

The exception to this is where the handle is positioned at the bottom of the window pane, and your window requires 2 shutter panels. Where this is the case, we will provide a window handle packer, which will need to be inserted under the handle base so that the handle clears the shutter.

Where a rebate is provided, the vast majority of window handles will turn without catching the rebate. However, if your handle does catch the rebate, please contact [email protected] and we will provide you with a slim (2mm or 6mm) window handle packer in order to provide extra clearance.

Yes Perfect Fit Shutters are really easy to install. No drilling or screwing is required. In fact, you don't need any tools. Watch the video guide below to find out more.

Perfect Fit Shutters project outwards from the window frame by 30mm (3cm) and they overlap past the edge of the visible glass by 23mm each side, at the top and at the bottom.

Yes, one of the benefits of Perfect Fit Shutters is that they can be easily removed from your window or door. You may wish to remove them so that you can clean behind them once in a while. You can watch the video below to find out just how easy it is to remove them.

The slats on Perfect Fit Shutters can be tilted open and closed using a tilt rod which can be positioned on the left or right hand of the shutter panel. 

However, the shutter panel is fixed directly to the window beading andthis means that the panel is not hinged and cannot swing open and closed like traditional shutters.
