Hunter Douglas Vertical Blinds are custom, high quality smooth vinyl blinds that define what window fashion is today. This category consists of both curved and flat smooth PVC, so be sure to check the color swatch to verify which product you are selecting. Available in 3 1/2" vanes, or you can get the Vinylscapes Flat Vertical in 2" vanes for a small upcharge. There is a choice of headrails, the Paramount contoured headrail and the classic PermAlign headrail (both Ivory). The two valance options top the look for a more finished appearance.
