Here's how to measure a Cyclone 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 150mm 165mm 180mm and 205mm 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: 68mm wide each (x 2) = width of window plus 136mm.
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 53mm 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. 150mm box is 150mm high x 150mm wide).

Please note: To comply with the Cyclone Rating the shutter must be fitted with a Bottom Guide to the full width of the exposed curtain, allowing the curtain bottom bar section to close down into the bottom guide section.
Please note: To comply with the Cyclone Rating, the shutter must be 4 square meters or less in overall size.
