How to Install Outside Mount Plantation Shutters
Outside-mount shutters are fixed to the wall or architrave around the opening, so careful frame positioning is essential before the first permanent fixing.
Preparation
Confirm that the finished frame dimensions match the intended opening and that the mounting surface is clear. Group the labelled frame and panel components for that window.
1. Assemble the frame
Join the frame on a flat surface and keep the corners fully seated.
2. Centre and level the frame
Hold the assembled frame over the opening. Confirm the top is level and the side margins are located as planned.
3. Fix the top and establish square
Use initial fixings to support the frame without fully tightening every point. Measure diagonals or use a square to establish the frame geometry.
4. Fix the sides and bottom
Work around the frame gradually. Pack behind low spots so the wall or architrave doesn’t distort the frame.
5. Hang the panels
Fit panels to their labelled hinge positions and test movement.
6. Fine-tune
Adjust frame packing or hinge alignment until panel gaps are even and the panels close cleanly.
7. Finish
Fit cover caps or strips, eliminate protective material and test the louvres and underlying window.
