Cordless Cellular Shades 45in x 64in Black - No Tools No Drill TDBU

In this review of the LazBlinds cordless cellular shade, the bottom line is simple: it is a practical, renter-friendly blackout solution for inside-mount windows that need privacy and thermal insulation. The installer found the No Tools-No Drill system genuinely quick and clean, and the top-down bottom-up design offers flexible light control without dangling cords. For anyone who needs a reliable room-darkening shade that presses neatly into a 45in window frame and keeps noise and heat transfer down, this shade delivers the core benefits with minimal fuss.

Key Features

• Inside mount design: The shade is built for inside-mount installation with a standard 3/8 in deduction so the delivered blind measures 44 5/8 in wide for a precise fit.
• No Tools-No Drill system: Patented hardware installs in seconds without screws or brackets, protecting window frames and ideal for renters and landlords.
• Cordless top-down bottom-up: The cordless operation gives a tidy appearance and safer environment for children and pets while allowing flexible light control.
• True blackout cells: A silver-plated layer inside the honeycomb cells blocks sunlight and UV for daytime sleeping and improved privacy.
• Thermal and sound benefits: The non-sagging cell structure insulates against heat and cold and helps reduce exterior noise for a calmer room.
• Expandable fit tolerance: A spring rod extends up to 1 in so the blind fits window widths from about 44.7 in to 45.6 in with a minimum frame depth requirement.

Who It's For

This shade is best for renters, apartment dwellers, and homeowners who want a blackout option without modifying window frames, and for anyone who prefers a cordless design for child safety and a cleaner look. It suits bedrooms, media rooms, and nurseries where complete or near-complete darkening and thermal performance are priorities.

Those who need an outside mount option, custom wider widths, or an extremely shallow frame below about 1 1/5 in depth should look elsewhere, since this model is designed specifically for inside mount applications and requires that minimum frame depth.

Pros & Cons

Pros

• Very quick installation with the No Tools-No Drill system, praised by customers for being done in minutes.
• Effective light blocking thanks to the silver-plated blackout cells, delivering a dark sleeping environment during daytime.
• Clean cordless operation and top-down bottom-up functionality let users adjust privacy and daylight without cords.
• Insulating cell structure provides measurable thermal and noise reduction benefits.

Cons

• Inside-mount only and requires a minimum frame depth of about 1 1/5 in, so it will not work on very shallow returns or some retrofit installations.
• Fit relies on the spring rod tolerance; very unusual window sizes outside 44.7 in to 45.6 in will need a different size.
