27in x 64in Cordless Cellular Shades TDBU - White No-Drill Fit

Our review of the 27in x 64in cordless cellular shades finds a practical, renter-friendly option for anyone who wants a tidy, cordless window covering without altering the frame. This white honeycomb shade is designed for inside mount windows and uses LazBlinds patented No Tools-No Drill system, so the biggest reason to buy is hassle-free installation combined with the safety and clean look of a cordless design. It balances light filtering and privacy while adding a thermal layer that helps reduce drafts and external noise.

Key Features

• Inside mount sizing: The shade is made slightly narrower for inside mounts and the actual blind measures 26 5/8in W x 64in H so it fits window openings about 26.7-27.6in wide.
• No drill installation: The patented No Tools-No Drill system installs without screws or brackets, letting renters and homeowners fit the shade quickly without damaging the frame.
• Cordless top-down bottom-up: The mechanical TDBU stopper allows independent positioning of the middle rail for controlled light and air flow while keeping the bottom rail from lifting the middle rail.
• Light filtering fabric: Soft non-woven polyester lets in a gentle, diffused light while retaining daytime privacy for living areas and bedrooms.
• Thermal honeycomb cells: The non-sagging cell structure adds insulation to reduce heat gain in summer and heat loss in winter, and also helps dampen outside noise.
• Strong mounting spring: The unique spring rod extends up to 1in and supports the shade in frames with a minimum 1 1/5in depth, holding the unit securely without tools.

Who It's For

This shade is best for renters, landlords, and home buyers who need a non-invasive, quick solution for standard inside mount windows and appreciate a neat, cordless look. It is also a good fit for families with children or pets who want a safer, tangle-free window treatment and for rooms where gentle light filtering and added insulation matter.

It is not ideal for someone who needs outside mount options, custom frame depths under the 1 1/5in minimum, or complete blackout performance; buyers needing room-darkening blackout or specialized exterior mounting should look elsewhere.

Pros & Cons

Pros

• Easy, damage-free install with the No Tools-No Drill system that renters will appreciate.
• Clean cordless appearance improves child and pet safety while letting in filtered light.
• Honeycomb cells provide real thermal insulation and slight sound reduction for comfort.

Frequently Asked Questions

Does this require drilling into the window frame?
No; the shade uses a patented No Tools-No Drill spring rod system so no drilling, screws, or brackets are required.

Will it fit my window if my frame is shallow?
The shade needs a minimum frame depth of 1 1/5in for a proper inside mount, so very shallow frames will not be compatible.

How much light does it block?
This model is light filtering: it softens and diffuses sunlight while providing daytime privacy but is not a blackout shade.
