Here's how to measure a Rollershutter
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 eaves or above window, or level with the window, or partly in the window space, etc, to your preference.
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: 55mm wide each (x 2) = width of window plus 110mm.
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.
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).
The BC45 Box style.
