Cordless Cellular Shades 35in x 64in Beige TDBU - Blackout Thermal

In this review the LazBlinds No Tools No Drill Cordless Cellular Shades are evaluated for renters and homeowners who want easy, damage-free installation and true room darkening. The biggest reason to consider these shades is the combination of a genuine blackout honeycomb fabric and a no-drill installation system that fits inside-mount windows without tools, making it practical for anyone who needs a quick, neat solution for privacy and light control.

Key Features

• Inside mount only: The shade is made 3/8 in narrower than the nominal width for a precise inside fit, helping ensure a neat installation inside the window frame.
• No Tools-No Drill system: Patented hardware installs in seconds without screws or brackets, preserving window frames for renters or those who want a temporary fit.
• Cordless top-down bottom-up: The TDBU mechanism lets you lower the top or raise the bottom for flexible light and privacy control while keeping a tidy, child-safe look.
• Real blackout lining: A silver-plated internal layer blocks sunlight and UV, delivering a dark environment suitable for daytime sleeping or media rooms.
• Thermal honeycomb design: Non-sagging cells trap air to reduce heat transfer and help dampen outside noise for better temperature and sound performance.
• Adjustable fit: The unique spring rod extends about 1 in so the actual blind (34 5/8 in x 64 in) will fit window widths from roughly 34.7 to 35.6 in.

Who It's For

This shade suits renters, landlords, and homeowners who need a quick inside-mount solution that does not require drilling or permanent hardware and who want true blackout performance. It is ideal for bedrooms, media rooms, or nurseries where day-darkening and child safety are priorities.

Customers who need outside mount shades, very shallow frames under the 1 1/5 in minimum depth, or custom widths outside the specified fit range should look elsewhere. Also, those who prefer motorized or cord-operated options will need a different product.

Pros & Cons

Pros

• Quick, tool-free installation that preserves window frames and takes under a minute once measured.
• Effective room darkening thanks to the silver-plated blackout cell lining.
• Cordless TDBU operation offers flexible light control and improved child safety.
• Thermal honeycomb structure provides insulation and some noise reduction.

Cons

• Inside mount only with a minimum frame depth requirement, so not compatible with every window.
• Width tolerance requires careful measuring since the actual blind measures 34 5/8 in and relies on the spring rod fit range.
