Arch windows are beautiful but sometimes you need complete darkness. Bali Blackout Cellular Arch shades are custom-made to fit your window's unique shape perfectly. The blackout honeycomb fabric blocks all sunlight completely, giving you the deep darkness you need for quality sleep and privacy. The intelligent design reduces heat transfer by up to 74 percent in summer and absorbs up to 70 percent of outside noise. That means lower energy bills and a quieter home. Choose cordless control for simplicity or add smart motorization to open and close shades with your phone.
