38in x 64in Cordless Cellular Shades TDBU - White Blackout

In this review of the 38in x 64in cordless cellular shades, the bottom line is simple: these inside-mount, top-down bottom-up blinds are best for renters or homeowners who want quick, tool-free installation and genuine blackout performance. The reviewer found the No Tools No Drill system genuinely easy to use and appreciated the cordless design for a clean look and safer home. The real blackout silver-plated cell and the thermal honeycomb structure make this a practical option for bedrooms and media rooms where light control and insulation matter.

Key Features

• No Tools-No Drill system: installs without screws or brackets so renters can mount the shade in under a minute and avoid damaging the frame.
• Inside mount sizing: built to fit inside-mount windows with a standard 3/8 in deduction, so the actual blind measures 37 5/8 in W to fit 37.7-38.6 in openings.
• Top-down bottom-up operation: the patented mechanical stopper lets you lower the top or raise the bottom independently for flexible light control and privacy.
• Cordless design: provides a tidy, child- and pet-safe window treatment that is simple to raise and lower by hand.
• Blackout silver layer: a silver-plated lining inside the cells blocks sunlight and UV for true room darkening during daytime naps or media viewing.
• Thermal honeycomb cells: non-sagging cells add insulation and help reduce outside noise and heat transfer for improved comfort year round.

Who It's For

This product suits renters, homeowners, and anyone who needs a fast, noninvasive installation and reliable blackout performance. Buyers who want an inside-mount shade with adjustable privacy will appreciate the top-down bottom-up feature and cordless operation.

It is less appropriate for windows with less than 1 1/5 in of frame depth or for those who require an outside mount solution. Also, shoppers needing custom widths beyond the 37.7-38.6 in fit range should look for other sizes or custom options.

Pros & Cons

Pros

• Very easy installation with the patented No Tools-No Drill system that avoids drilling into the frame.
• Effective blackout performance thanks to the silver-plated cell layer that blocks daylight and UV.
• Good thermal and noise insulation from the honeycomb structure, improving comfort and privacy.
• Cordless, clean appearance that is safer for homes with kids and pets.

Cons

• Designed for inside mount only and requires a minimum frame depth of 1 1/5 in, so it will not work on all windows.
• Fit tolerance is specific (actual blind 37 5/8 in W) so precise measuring is required to ensure compatibility.
