38.5in x 39in Blackout Cellular Shades Cordless - White Honeycomb

Our review of the 38.5in x 39in Blackout Cellular Shades finds them best for renters and light-sensitive sleepers who want a fast, damage-free solution. The single biggest reason to buy is the no-drill, cordless install system that really does let one person fit the shade in about 30 seconds without tools or wall damage, while delivering true blackout performance and noticeable thermal insulation.

Key Features

• No-drill installation: The damage-free mounting installs in roughly 30 seconds so renters can add window coverings without tools or holes.
• Cordless safety: The cordless, spring-driven operation offers a quiet, pet-friendly glide ideal for nurseries and busy households.
• Blackout and insulation: The honeycomb construction blocks light effectively and traps air to reduce heat transfer by about 40% for better temperature control.
• Durable construction: A rust-proof aluminum frame and fade-resistant fabric are lab-tested for 10,000+ lifts and extremes of temperature and humidity.
• Custom fit reminder: Widths are trimmed 3mm by default for a precise fit and the seller double-checks measurements to avoid sizing errors.

Who It's For

This shade is aimed at apartment dwellers, renters, and anyone who wants a quick, no-damage install. It suits bedrooms, home theaters, and rooms that need strong light blocking and improved insulation, especially for night shift workers or light-sensitive sleepers.

Those who need motorized controls, blackout beyond a single-panel solution for very large windows, or extremely precise light-gap elimination at irregular frames should look elsewhere. Professional installers or customers who prefer hardware-mounted permanence may prefer a different system.
