Do you know your mouse holes from your mid rails and your slats from your stiles? Our handy Glossary will have you speaking fluent Shutterese in no time.


The panel is the main, rectangular part of the shutter, hinged so it can open. Normally panels contain moveable slats, but on solid shutters, the panels are completely wooden.

Your shutter panels are mounted inside a shutter frame. The frame is mounted onto the window (or inside the window recess), creating a perfectly squared shape for the shutter panels to be mounted into.

Mouse hole
The mouse hole is a dip in the rails where the push rod sits when the slats are closed. (You don’t get this with hidden push rods.)

Top rail
A top rail finishes off the top end of the shutter.

Bottom rail
Guess what - a bottom rail finishes off the bottom end of the shutter.

Mid rail
Mid rails run horizontally between the top and bottom rails and add extra strength to your shutters. They also let you control the top and bottom slats separately.

Slats (also called blades and louvres)
Slats are the horizontal pieces which tilt and rotate around 340° to let in light and give a better view outside. They come in four different sizes:

  • 64mm – our best selling slats and a brilliant all-rounder. You can see out clearly when they’re open, they let a lot of light in and they fit most windows including French doors.
  • 76mm - a recent addition to our offering. If you want to maximise your view and allow lots of light to come into the room, then choose this slat. This larger slat is already our 2nd best selling and is suitable for all window sizes. Remember to choose the correct frame depth as you increase your slat size. 
  • 89mm – our second best selling size, these are growing in popularity. They add a more contemporary touch and allow a lot of light into the room, too.
  • 114mm – these slats look great on large windows and make a bold statement, especially when their size is in proportion to the room and the height of the window.

Stiles are the vertical rails at either side of the panel.

Central Tilt Rod
The central tilt rod is a vertical rod in the middle of each panel. The rod connects the slats and can be used to open and close them. 

Offset Tilt Rod
Similar to the central tilt rod, however the vertical  rod is 'offset' to one side of the panels. 

Clearview Tilt Rod 
The design is more contemporary than the traditional options above. There is a thin metal rod connected to the back of the slats on each panel. It is offset to one side so that your view is unobstructed when the slats are titled open. 

Invisible/Hidden Tilt Rod
The connecting rod mechanism is hidden within the stile of the panel and connects all moving slats. 

Hidden split
Shutters taller than 1300mm without a mid-rail require a split in the Clearview or Hidden tilt rod. You can request a split in a specific location, and if no location is requested then your order will automatically receive a split in the centre of the Clearview/Hidden rod. Having this split ensures seamless slat closure for your shutters.

Café Style Shutters
These shutters cover the lower half of your windows, so they let lots of light in and give you privacy. Their design is similar to the shutters you’d find in Parisian cafés.

Full Height Shutters
These shutters cover the entire window and open as one unit, creating a clean, simple look. Beyond a certain height, full height shutters will need a mid rail to strengthen them.

Tier on Tier Shutters
These cover the whole window, but you can open the top and bottom independently of one another, a bit like a stable door. This style is ideal if you like the café style look, but want more privacy.

Solid Shutters
Traditional and secure, these top-to-bottom shutters are available completely or partially solid. These are available in our 'raised' solid design in our Smooth Hardwood range.
