What should I pay attention to when installing wooden shutter?

Accurate measurement: A 5mm gap is required for embedded installation (to prevent thermal expansion and contraction from getting stuck), and an external installation must extend 10cm beyond the window frame.

Load-bearing test: The width of a single sash is recommended to be ≤1.5 meters, and if it is too wide, it needs to be divided into sashes or a central bracket is installed.

Accessory selection: Use stainless steel screws to avoid rust; it is recommended to install moisture-proof pads in humid areas.
