Cordless Cellular Blackout Shades 28in x 64in - Thermal, Noise

In this review of the LazBlinds cordless cellular shades, the bottom line is simple: these are a budget-friendly blackout solution for bedrooms and rooms where light control and insulation matter. They deliver genuine darkness thanks to a silver-plated inner cell layer and reduce heat transfer and outside noise with a 3/5in cell structure, making them attractive for anyone wanting better sleep, lower heating and cooling loss, or a neater, cord-free window look.

Key Features

• True blackout: a silver-plated layer inside the cell blocks sunlight and UV rays to produce a dark room ideal for daytime sleepers.
• Cordless operation: the cord-free design creates a safer environment for children and pets while offering smooth, tangle-free up and down motion.
• Thermal insulation: the 3/5in honeycomb cells trap air to reduce heat transfer in summer and retain warmth in winter, helping lower energy costs.
• Noise reduction: the cellular structure dampens outside sounds, improving conditions for sleep or focused work.
• Adjustable height: the shade height can be set anywhere from 0in to 64in so the single size can accommodate varied window heights without trimming.
• Mounting options: supports both inside and outside mounts with clear sizing guidance for best coverage.

Who It's For

The LazBlinds blackout cellular shade is best for homeowners and renters seeking an affordable way to create a dark bedroom, nursery, or media room. It suits families because the cordless design reduces strangulation risk for children and pets and the durable cells hold shape while providing insulation.

People who need exact custom fittings or motorized controls should look elsewhere; these shades are a manual, budget-focused option and while sizes are adjustable up to 64in high, truly custom features or automation are not part of the offering.

Pros & Cons

Pros

• Effective light blockage from the silver-plated inner layer delivers near-total darkness for daytime sleeping.
• Cordless design provides a clean look and safer operation for homes with kids or pets.
• Honeycomb cells add measurable thermal and sound insulation, which can reduce seasonal energy use and outside noise.
• Easy installation reported by customers and simple snap-in mounting hardware for most standard frames.

Cons

• Inside mount requires at least 1 2/5in frame depth, so some windows may need an outside mount or alternate solution.
• Manual control means no motorized option for users who want remote operation or smart-home integration.

Specifications

Our Verdict
