Blackout cellular shades block 99% of all incoming light and UV rays and are energy-efficient shades that stop solar heat gain. they add insulation to your windows that repel dust and are easy to clean.
*Note that the fabrics are blackout, but the overall effect is not absolute blackout. Blinds and shades cannot fit perfectly tight to the sides of the window, which creates “light gaps”. Slats would scrape the window frame during motion, causing damage.
