TDBU Double Cell Cellular Shades | Top Down Bottom Up | Light Filtering

Want natural light without sacrificing privacy?
Our honeycomb top down bottom up shades give you the best of both worlds. Lower the top panel to let soft, diffused daylight flow in from above — while keeping the bottom raised so neighbors can't see in. Among the most versatile top down bottom up window blinds available, they're perfect for living rooms, home offices, and any space where you want brightness without exposure. Available in a refined earth tones palette — soft clay white, warm flax, and natural parchment — that pairs naturally with timber floors, linen sofas, and the understated interiors trending across the US, Canada, and Australia.

Frequently Asked Questions

Q: Are double cell shades worth it compared to single cell?
A: Yes — for most homes, double cell shades are worth the upgrade. The second honeycomb layer significantly improves thermal insulation (R-value), which means better temperature regulation year-round and lower energy bills. If your windows face west, north, or are in a room that runs hot or cold, double cell is the right choice. Single cell works for mild climates or interior rooms where insulation is less critical. → See our full R-Value Comparison Guide

Q: What is the most popular size for TDBU light filtering honeycomb blinds?
A: The 34" wide × 64" high is our top-selling size, making it the ideal choice for standard living room and home office windows in North American homes.

Q: How do I measure for TDBU cellular shades?
A: Measure width at three points (top, middle, bottom) and use the narrowest measurement. Measure height at three points (left, center, right). For a complete step-by-step guide including inside vs outside mount instructions, see our Measuring & Installation Guide.

Q: What is the difference between light filtering and blackout honeycomb blinds?
A: Light filtering blinds allow soft, diffused natural light to pass through while maintaining privacy — perfect for living rooms and offices. Blackout blinds block 100% of light, making them ideal for bedrooms and media rooms. For a full room-by-room breakdown, see our Blackout vs Light Filtering Blinds guide.

Q: What room works best with TDBU light filtering blinds?
A: Living rooms, dining rooms, and home offices are the most popular applications — the light filtering fabric softens harsh sunlight while the top-down bottom-up design gives you precise control over light and privacy.

Q: How does the top-down bottom-up (TDBU) feature work?
A: You can lower the top panel to let in light from above while keeping the bottom raised for privacy, or raise the bottom panel for a traditional look. Both panels move independently for maximum flexibility.

Q: How do I choose between single, double, and triple cell shades?
A: The key difference is insulation performance (R-value). Double cell shades offer significantly better thermal efficiency than single cell — ideal for most homes in the US, Canada, and Australia. → Read our complete R-Value Comparison Guide
