Here's how to measure a Rollershutter

Height Measurements

Ensure you measure both sides of the opening and use the smallest of the two sides as your final measurement 

Face Fix/Flush (FF)
OH (overall height) 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: Face Fix/Flush (FF) has greater flexibility and is more accepting of 'out of square' windows.

Reveal/Built in (BI) :
While under construction

Please note: Reveal/Built in allows for zero margin for error in measurements.

Width Measurements

Ensure you measure the total width of the window and use the smallest of the two as your final measurement

Face Fix/Flush (FF)
FF is the window opening plus the width of the guides.

Rollershutter guides: 60mm wide each (x 2) = width of window plus 120mm.

Please note: On wall (FF) 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: Reveal/Built in (BI) allows for zero margin for error in measurements.
