Single Window - Interior
The prerequisite for this type of installation requires a clearance of 2 inches deep from the frame without obstacle to the bottom of the frame. The measurement of the width must be taken only at the top of the frame, this canvas when descending leaves +/- 1/2 inch of clearance on each side of the canvas when descending.
It is very important to take the height in three different places like figure-1 below and keep the smallest measurement. The alternating shade is made so that it comes 1/8 inch from the bottom of the frame in the privacy position, and will rise a little in the daytime position, which aligns the curtains so that they can see the outside.

If you want the box of the alternating canvas to be equal to your frame, you simply take the outside measurement of the frame on the width and if you want to completely cover your frame with the canvas then you must add 2 inches to this measurement.
For the height you have 2 options, so if you want to install the case of the alternating canvas on the frame then take the outside measurement of the frames on the height. However, if the box is installed at the top of the frame, you must add 3 inches to this measurement.
