Hunter Douglas Nantucket™ window shadings combine innovative design with style and versatility to simplify your life and your surroundings. Soft 2 1/2″ translucent fabric vanes are suspended between two sheer fabric facings. With the shading lowered, the vanes can be tilted to any position from fully open to closed. With the vanes open, the sheer facings soften the outside view and filter the incoming sunlight — and block up to 88% of harmful UV rays. With the vanes closed, you enjoy complete privacy without complete darkness — and 99% UV protection. With the shading raised, the fabric is totally concealed inside the headrail.
