Top-Down/Bottom-Up Cellular Shades

Top-Down/Bottom-Up (TDBU) operation is the most versatile way to control light and privacy. Unlike standard shades that only raise and lower from the bottom, TDBU shades allow you to lower the top of the shade independently, creating a "cafe-style" configuration that admits light and air while maintaining privacy below. You can also raise the bottom conventionally, position the shade at any intermediate point, or fully raise or lower both rails. This flexibility makes TDBU shades the ideal choice for rooms where privacy and natural light are equally important—street-level living rooms, first-floor bedrooms, bathrooms, and nurseries. Our TDBU Cellular Shades are available across all cell sizes (¾-inch and 1⅛-inch), all opacities (light-filtering, room-darkening, blackout), and our full palette of 30+ colors. Custom‑sized to your exact window dimensions, with cordless wand operation. Privacy on your terms, daylight on demand.

How TDBU Operation Works

TDBU shades feature two independent rails—a top rail and a bottom rail—each with its own lift mechanism. This gives you complete control over light and privacy:

  • Lower the top rail to admit light and air while keeping the bottom rail fully lowered for privacy

  • Raise the bottom rail conventionally while the top rail stays in place

  • Position both rails at any intermediate height

  • Fully raise or fully lower both rails for an unobstructed view or full coverage

This dual‑direction flexibility adapts to every lighting need throughout the day.

Ideal for Every Room

  • Street‑level living rooms — Light from above, privacy below

  • First‑floor bedrooms — Privacy for sleeping, gentle light for waking

  • Bathrooms — Daylight without exposure

  • Nurseries — Soft light for playtime, darkness for naps

  • Home offices — Glare‑free light from above, privacy for video calls

  • Sunrooms — Precise control over light and heat gain

Cordless Wand Operation

All TDBU cellular shades use cordless wand operation—no dangling cords, no loops. Two independent wands (one for each rail) attach magnetically and can be removed and stored out of reach. A gentle push or pull operates each rail independently. This system meets the highest child‑safety standards.

Available in All Opacities

  • Light‑Filtering TDBU — Soft, diffused daylight with daytime privacy

  • Room‑Darkening TDBU — Enhanced privacy and reduced glare

  • Blackout TDBU — Total darkness with top‑down flexibility

All opacities are available in the same color palette, allowing seamless mixing throughout a home.

Thermal & Acoustic Benefits

TDBU shades provide the same thermal insulation and sound absorption as standard cellular shades. The honeycomb cells trap still air regardless of shade position, so you never sacrifice energy efficiency for flexibility.
