Top Down Bottom Up

TDBU refers to a blind that can be raised from the bottom up (Bottom-Up) or lowered from the top down (Top-Down). This allows you to maintain privacy by keeping the bottom section closed while still letting natural light in from the top.Both drilled and no-drill installation options are available. All Roman shades, honeycomb blinds, and roller shades include detailed instructions and all necessary hardware. No professional tools are required, and most installations are completed independently within 15–30 minutes.

Traditional curtains/blinds can only be raised from the bottom or lowered completely, making it impossible to simultaneously manage “light intake” and “privacy screening.” Top-down/bottom-up blinds, however, can be lowered from the top, allowing light to enter through the upper portion of the window or providing a view of the sky while simultaneously covering the lower section to protect privacy.We support full-size customization, allowing for free combination according to window size, fabric, color, etc.

They're perfect. Windows like this often require both natural light and privacy. You can lower the blinds slightly from the top to let in daylight while keeping the bottom covered.Blackout fabric products provide 100% light blocking. Honeycomb blinds feature a hollow-cell structure, delivering superior heat insulation and energy efficiency, which reduces air conditioning consumption. These products are ideal for bedrooms, studies, and similar spaces.

No need to worry about complicated installation—we offer many drill-free options that take just 5 minutes to install.Roman/roller shades: Wipe with a damp cloth or gently hand wash, then air dry flat.
Honeycomb blinds: Spot clean with a mild detergent; avoid soaking the entire unit.
Machine washing is not recommended to protect fabric and structural integrity. For motorized models, regular inspection of motors and wiring is advised, and contact with water must be avoided.

They are typically slightly more expensive due to their more complex mechanisms and additional features. However, many buyers consider them worth the value for the benefits they offer: enhanced privacy, improved light control, and energy savings.All products carry a 1-year warranty.
