Measure properly to get the right fit for your skylights and arches
Arches and skylights are wonderful ways to add extra light and warmth to your home. And outfitting these specialty products with window treatments can be easy. While you can find custom wood, faux wood and cellular shades for arches along with cellular shades for skylights at The Home Depot, we highly recommend calling us at 1-800-921-2119 so we can help you through measuring for these products.
Measuring for a skylight or arch is simple and you can do it yourself, saving time and money.
This project guide highlights the process for measuring for arches and skylights, and creating an accurate measuring template for your odd-shaped windows.
WHAT YOU NEED FOR THIS PROJECT
• An inside mount means you want your arch shade to fit inside of your skylight or arch window. Measuring for outside mount arches is the same as measuring for inside mount arches. The factory will make the necessary adjustments. However, with cellular shades, you will need to add 2 inches to the width and height of your initial measurements.
• For both inside and outside mounts, measuring arches is simple.
• First, measure the base width inside the arch opening. Then measure the height at the middle, or tallest point inside of the arch opening.
• A perfect arch means that the height of the arch will be exactly half the width of the base measurement. If it turns out that your window is not a perfect arch, give us a call at 1-800-921-2119 so we can help you and discuss your options.
• Inside mounts: While most other inside mounted products requires you to round down, you should round skylight measurements for inside mounts up to the nearest 1/8 inch. Deductions will be taken from your product that will allow for the rail seal, the foam tape that will be on the outside of the rails.
• Your skylight will need at least 2 inches of mounting depth inside the window for your product to be fully recessed. We highly recommend that you do not use a non-flush mount. However, if there's no other alternative, it is acceptable for your shade to stick out up to ½ inch from the window. Please account for anything in the window frame that might interfere with how the shade operates.
• On your order, please include the angle of the window, in addition to its measurements.
• Outside mounts: With skylight shades, the procedures for outside mounts are the same as for standard rectangular shades.
• Make your measurements in three separate places in your window for both width and height. For a skylight window that is longer than 96 inches, be sure to make a measurement every 48 inches. Outside mounts require only a ½-inch flat surface for bracket attachment.
1. Attach butcher paper or wrapping paper to the window, allowing space for lots of overlap. Make sure the paper has no folds, as this can cause inaccuracy.
2. Trace the inside of the window frame and create an exact outline of the window with a pen or marker.
3. Remove the paper from the window.
4. Write the measurements of the shade down on the piece of paper. Make sure the dimensions match your actual window. You can test this by cutting out the drawing and placing it back against the window.
5. Please label the template clearly. Include your name, and label the "Top" and "Room Side" of the window appropriately. Roll, not fold, the template and insert it into a mailing tube with your order.
