Measure the inner frame size
1. Width Measure the width of the inner frame of the window from left to right, and subtract 1cm from the minimum width of the upper, middle and lower window, which is the suitable width of the inner frame.
2. Measure the height of the inner frame of the window from top to bottom. The minimum height of the left, middle and right windows is the suitable height of the outer frame.
3. Make sure that the window depth is enough for the shutter blades to move freely. Different shutter installation methods require different window depths.
4. 8cm depth is required for fixed or flat installation.
5. In addition to considering the width of the product blade, the number of layers of the installed product should also be considered during push-pull installation.
6. Generally, two-layer push-pull requires 15cm depth to ensure blade movement, and 10cm depth for single fan; 10cm depth needs to be reserved for folding installation
