Polyester & Polyester Blend Attention: Measure for Inside Mount: The shade you order will be the exact size with no deductions. To ensure a proper fit, measure the width of your window at the top, middle, and bottom. For a 24" wide shade, your window should measure between 24.25" to 25" wide, allowing for a snug fit with minimal light gaps. Next, measure the height from the top of the window to the windowsill on the left, middle, and right sides, and use the largest height measurement when placing your order. Unique Honeycomb construction offers insulation and sound absorption. Features a cordless lift system that is safe for children and pets. Hardware is included for inside or outside mounting, preferably on drywall. Each cordless cellular shade comes with a matching PVC headrail and bottom rail. We suggest that you order a quantity of one item before ordering a greater amount to test the overall product. We try to edit our photos to show the samples as life-like as possible, however the actual color may vary since each computer monitor has different capabilities to display colors and that everyone sees these colors differently. This product is highly recommended for indoor use only. Questions? Please contact us at the CalyxInteriors website.
