Here's how to measure a Commercial Roller Shutter
Height Measurements
Ensure you measure both sides of the window and use the smallest of the two sides as your final measurement
On wall installation (OW)
OW is optional in its placement: to the eaves or above the window, or level
with the window, or partly in the window space, etc, to your preference.
Please note: The overall height of the Rollershutter is to the top of the head box,so if the head box is above the window or door use the table below to calculate the overall height of the Rollershutter.
The head box increases in sizes from 180mm 205mm 230mm 250mm and 300mm in relationship with the height see the table below
Please note: On wall (OW) has greater flexibility and is more accepting of 'out of square' windows.
In-Reveal installation (IR)
IR is determined by the sill and above-window opening (lintel), as illustrated
above.
Please note: In-reveal (IR) allows for zero margin for error in measurements.
Width Measurements
Ensure you measure both top and bottom of the window and use the smallest of the two as your final measurement
On wall installation (OW)
OW is the window opening plus the width of the guides.
Rollershutter guides: 76mm wide each (x 2) = width of window plus 152mm.
Please note: On wall (OW) has greater flexibility and is more accepting of 'out of square' windows.
In-Reveal installation (IR)
IR width is determined by the window aperture at its smallest point (e.g. the top of the window may measure 1200mm but the bottom may measure 1203mm and the middle measures 1205mm - your measurement should then be 1200 for overall width).
Please note: In-reveal (IR) allows for zero margin for error in measurements.
Please note: That some outward opening windows and doors many not open with In-reveal (IR) installation. The guide is 76mm wide and may interfere with outward opening windows and doors, in this case use (OW) installation
Headbox Sizes
In case you are wondering "But how far will that 'Box' thing stick
out?", the table below shows the relation between a Rollershutters'
size and how big the Head Box will be.
The height of the head box for the BC45 is the same as the width of the box (i.e. 180mm box is 180mm high x 180mm wide).

Please note: Although 90% of windows have sills, if your windows don't,
then don't despair! We have a solution to that.
We can supply a false sill which all rollershutters needs for the curtain
to fully close down on.
The sill is aluminium and would be the same colour as the headbox and guides and come in 3 sizes
24mm x 22mm, or 24mm x 46mm, or 24mm x 77mm
Does your window frame protrude out past the exterior wall
If your window is protruding out past the exterior wall, it will interfere with the operation of the shutter. This can be easily over come, we can supply an aluminium angle that would be the same colour as the headbox and guides, and they come in 3 sizes - 24mm x 22mm, or 24mm x 46mm, or 24mm x 77mm.
This angle with it's 24mm side is fixed to the wall, allowing it then to protrude out from the wall 22mm or 46mm or 77mm. The guides that support the Rollershutter are 76mm wide x 28mm thick, so allowing for the thickness of the guide 28mm, the 22mm x 24mm angle would give a flush fit, the 46mm angle would give you a space of 18mm, and the 77mm angle would give you a space of 49mm. If you have a sill you will need 3 angles (one each side and one for the top), if there is no sill you will need 4 angles. Fit these angles to the wall with the angles facing inward so they are hidden behind the Rollershutter, then fasten the Rollershutter to the angles.
