INSIDE MOUNT

STANDARD WINDOW – INSIDE MOUNT – BLIND IS FITTED INSIDE THE WINDOW OPENING

It is an industry standard for Roman blinds fitting into the window reveals to sit flush with the front of the reveal. The factory will make the appropriate deductions for the product type and fixing position.

FACTORY STANDARD DEDUCTIONS  
INSIDE MOUNT WIDTH DEDUCTION 10mm
INSIDE MOUNT DROP DEDUCTION 5mm

When drawn up the Roman Blind folds will sit back further than the head rail. This will vary depending on the drop and style of the Blind and could be as much as 70mm.
Ensure that the reveal is deep enough.

WIDTH

  • Measure neat internal width of reveal

DROP

  • Measure neat internal drop of the reveal.
  • Measure at three drop points – left, middle and right of reveal.
    Use the shortest drop measurement.
