Single-cell shades are an attractive and classic treatment for small and medium-size windows. Crafted of polyester honeycomb, these shades filter out all but the softest light. Deceptively soft, yet sturdy fabric keeps the 3/8" pleats crisp for years. Each beautiful color is backed with white for consistent appearance from outside. Darker colors filter light more dramatically than lighter colors, which effectively cut sun glare. Every gorgeous, fade-proof color blocks nearly 100% of UV rays.
