Choose Blackout Honeycomb Window Shades for the rooms that require ultimate darkness. Cellular window treatments protect your home from the harmful UV rays and offer greater light and privacy control. They also protect your home from heat and cold as they are one of the most efficient insulators. They add style and efficiency to your home in a single go. When you install these Cellular Shades, you can save on your energy bills as they insulate your home from the external heat and cold. As a result, you tend to use your heater and air conditioner less than before.

Blackout Honeycomb Shades with Side Channels

Blackout Side Channels help block any light leakage that might happen when you mount your shade inside your window opening. Since the shade is smaller than the opening, there is usually a small light gap on the left and the right side. When you choose blackout honeycomb shades with side channels, you can get complete light blockage in your window for ultimate comfort.

- Energy Efficiency
- Energy Saving Blackout Sidetracks
- When properly installed, Slumbershades block 99% of all visible light. In certain installations with intense sunlight, a very small amount of light may reflect around the edges of the honeycomb fabric along each side of the shade. This is a normal attribute of the Slumbershade system
- Easy to Install and Remove
- Light Absorbing Technology
- The specially designed notched bottom rail end caps fit over the blackout sidetracks and allow for smooth movement when raising and lowering the shade
- To ensure the best possible dark sleeping environment, fuzzy seals are applied along the shade’s head rail. This barrier helps block out exterior light at the top of the shade
