Inside Mount vs Outside Mount Plantation Shutters
Quick answer: Inside mount sits inside the window reveal for a built-in look. Outside mount fits around the opening and is more forgiving when the reveal is shallow, uneven, tiled or interrupted by handles or trim.
When inside mount suits
Choose inside mount when the reveal is deep enough, reasonably square and clear of handles, tiles or obstructions that would stop the shutter operating cleanly.
When outside mount suits
Choose outside mount when the reveal is shallow, out of square, tiled, damaged or visually better covered by a frame around the opening.
Reveal depth matters
Frame choice depends on the depth and shape of the opening. Measure in millimetres and check the ordering guide before submitting sizes.
When to send photos
Send photos before production when there are handles, architraves, tiles, uneven reveals, large openings or uncertainty about L frame versus Z frame.
