General Window Terms
- Inside Mount - the shade in mounted inside a window the casing. Proper depth is required for inside mounting
- Outside Mount - the shade is mounted on the window casing or on the wall
- Casing (molding) - is the frame around the window
- Sill - projects like a shelf at the bottom of the window
- Apron - decorative molding that is below the sill
Inside Mount
Inside mounting your shade can give you a "built-in" appearance after it is installed. Please note that when you inside mount a shade, you will have small light gaps on both sides of the shade. This is caused by the lifting hardware and mounting brackets. Also, be aware of obstructions such as cranks and handles that can interfere with the operation of the shade. If you have obstructions or want more light blockage, then we recommend outside mounting
Inside Depth
Each product has a different headrail system for operating the shade. The size of the headrail varies from product to product and the depth of your window must meet the minimum depth for inside mount.
Inside Diagonal
Your window must be square for your shade to function properly. Measure the widow diagonally in two directions. If your measurements are different by more that 1/2", then you should not inside mount
Inside Width
Measure the width inside your window on the top, middle and bottom. Write down the
shortest of the three measurements. This is your width to order
The workroom makes a small automatic "inside mount" fit deduction from your ordered width. You do not need to calculate any width deductions yourself when ordering
Inside Length
Measure the vertical length inside your window on both sides and in the middle. Write down the
longest of the three measurements. This is your length to order. You don't need to add extra inches to the length for an inside mount
Outside (Wall) Mount
Outside mount shades must be mounted on the wall just above the window casing. We do not recommend mounting your shade directly on the window casing. Wall mounting allows you to increase the width of your mounting hardware beyond the casing so that your shade covers the window casing when lowered. We recommend that you add 2" to the casing width
Two Direction Measuring
Measure the outside casing to outside casing for the width. Then measure from the top of the casing to the sill. This is your length measurement. If you don't have a window sill, measure 1" past the bottom of the apron
