Overview
Where the frame sits changes the finished appearance, projection and measuring points. Establish the available recess depth and fixing surface before comparing the inside and outside arrangements below.
What is the difference between an inside and outside mounted shutter?
The mounting position changes the frame, projection and measurement boundaries. A recess-mounted shutter sits within the opening; a face-mounted shutter covers the wall or trim around it. The blades may operate similarly, but the dimensions for the two arrangements are not interchangeable.
Inside mount vs outside mount shutter
Compare the two diagrams using your actual recess and trim. An inside arrangement keeps the shutter closer to the window; an outside arrangement moves it into the room. Include the frame overlap and panel opening space when judging the finished look.
What is an inside mounted plantation shutter (recess fit)?
An inside fit uses the recess to carry an L-frame or Z-frame. Check 70 mm of blade clearance for an inside L-frame or 60 mm for a Z-frame, measured to the nearest obstruction. The Z lip covers the front edge; the L-profile leaves that edge exposed.
What is an outside mount plantation shutter (face fit)?
A face fit uses an outside L-frame on the architrave or wall. It is useful where an inside fit would collide with hardware or an opening sash. Confirm a flat fixing surface and enough space in front for the projection and moving panels.
