Cordless Cellular Shades Blackout Honeycomb Shades 19in x 36in - No

In this review the LazBlinds Cordless Cellular Shades are presented as a practical blackout option for renters and homeowners who want quick, tool-free installation. The biggest reason to buy is the patented No Tools-No Drill system that clamps into an inside window frame in about 30 seconds, giving a true dark room thanks to a silver-plated cell layer. The reviewer found them especially useful where drilling is not allowed and for rooms that need reliable light blocking and improved insulation.

Key Features

• No Tools-No Drill system: Installs in roughly 30 seconds so renters and landlords can fit shades without altering window frames.
• Real blackout cells: A silver-plated layer inside the honeycomb structure blocks sunlight and UV rays for a dark sleep environment.
• Cordless operation: Raises and lowers smoothly without exposed cords, improving safety for children and pets.
• Adjustable fit: The spring rod extends to fit slightly different inside-mount widths and the height is adjustable up to the full 36in.
• Insulating cell structure: The non-sagging 3/5in cell reduces heat transfer and can help with noise reduction compared with a bare window.

Who It's For

The shades are ideal for renters, landlords, and anyone living in a space where drilling is not permitted, since the patented clamp system works on many wall finishes including wood, tile, marble, concrete and rough surfaces when used inside mount. Bedrooms and nurseries benefit from the reliable blackout layer and cordless design for safety.

Those with very shallow window frames under the required 1 1/5in depth or who need an outside mount solution should look elsewhere, as these are designed strictly for inside mount installation with a recommended width deduction for a proper fit.

Pros & Cons

Pros

• Fast, tool-free installation that fits many window materials without drilling.
• Effective blackout performance thanks to the silver-plated inner layer for daytime sleeping.
• Cordless, easy operation and a neat, uniform honeycomb look that feels higher-end than the price suggests.

Cons

• Inside mount only with a minimum frame depth requirement, so it will not work on all windows.

Frequently Asked Questions

The silver-plated inner cell layer provides real blackout performance that significantly reduces daylight and UV for a dark room.

Do they work with small or irregular window widths?
