Are you looking for a window treatment that offers light control and insulation while providing modern styling? Enter our cordless top down bottom up cellular shades.
Blinds That Open At The Top
These cordless blinds that open at the top. You can easily lift the top rail to raise, or pull down on the bottom rail to lower your shade for both light and privacy — there are no cords to tangle and no hardware to snag; just a simple and custom-tailored look to any room.
Cordless TDBU widnow shades are operated by pushing or pulling on small handles or tabs located on the rails.
Cellular shades, as known as honeycomb blinds, come in single cell or double cell. Both types offer thermal insulation and soundproofing but in slightly different ways:
| Feature | Single Cell | Double Cell |
| Insulation | Basic thermal performance | Superior insulation (ideal for extreme climates) |
| Appearance | Sleek and minimal | Thicker and more structured |
| Light Filtration | Available in light filtering & blackout | Same options available |
| Best For | Mild climates, decorative spaces | Harsh climates, energy-saving needs |
Double cell cordless blackout shades work best in bedrooms or rooms exposed to the sun while single cell light filtering shades are a great for choice for kitchens and living rooms.

Inside Mount (Most Common for TDBU Cellular Shades)

Then measure the inside height at left, center and right.
Record the tallest height.
We will automatically subtract a narrow width (~1/4") for a snug fit.
Outside Mount

Outside mount can block more light and is ideal for shallow windows.
