TDBU Cellular Shades – Complete Collection

Top-Down/Bottom-Up (TDBU) is the most versatile operating system for cellular shades. 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. 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 (wand or cord). This allows you to:

  • 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 for customized light control

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

This dual‑direction flexibility gives you precise control over privacy, daylight, and comfort.

Ideal for Every Room

TDBU shades excel wherever privacy and natural light need to coexist:

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

  • Bathrooms — Daylight without exposure

  • Nurseries — Soft light for playtime, darkness for naps

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

  • Bedrooms — Gentle morning light while maintaining privacy

Cordless Wand Operation

All TDBU cellular shades feature 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 & Colors

TDBU operation is available across our entire cellular shade collection:

  • All cell sizes — ¾" single, 1⅛" single

  • All opacities — light‑filtering, room‑darkening, blackout

  • All colors — over 30 neutrals, blues, greens, and accents

  • All fabrics — Essential, Performance, Premier

No other operating system offers this level of compatibility.

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.

Easy Installation

TDBU cellular shades install just like standard shades. Mounting brackets are included, and the shade snaps into place. The dual‑wand system arrives pre‑assembled and factory‑calibrated. Full installation instructions and video tutorials are available.
