AOSKY Blackout Cordless Roller Shade for Windows, 35"W x 72"H White — Thermal-Backed, Cord-Free

This cordless roller shade from AOSKY is built for indoor windows and combines a true blackout fabric with a reinforced thermal backing. The shade measures 35" overall (fabric width 34"), reaches up to 72" in height, and uses a spring-loaded, cord-free mechanism for safe, easy control. It’s engineered to reduce window heat transfer, provide full light blocking, and fit either inside or outside window mounts when sized properly.

How does this shade block light and help regulate room temperature?

The fabric is 100% polyester with a reinforced thermal coating on the back that prevents most light and reduces heat loss or gain through the window. While it’s not a substitute for HVAC, the thermal layer helps moderate temperature changes at the glass, which can reduce drafts and solar heat in direct sun.

• 100% blackout fabric blocks sunlight and most UV.
• Reinforced thermal coating reduces heat transfer through windows.
• Soft, smooth polyester resists pilling and is easy to clean.
• Helps maintain room comfort and may lower cooling/heating load.

How do I choose the correct size and mount it properly?

Deciding between inside or outside mount determines the shade size: for outside mounts, add about 4" to window width to ensure full coverage; for inside mounts choose the exact window width or slightly smaller. Note that the fabric itself will be approximately 1" narrower than the published shade size, and overall height can be adjusted from fully lowered to 0" up to 72".

• Outside mount: order shade ~4" wider than window width (e.g., 30" window → 34" shade).
• Inside mount: order same width or slightly less for a flush fit.
• Fabric width ≈ shade width minus 1"; height adjustable up to 72".
• Requires at least 2" frame depth for bracket installation.

What makes the cordless mechanism safe and easy to use?

AOSKY’s cordless design eliminates hanging loops, making the blind safer around children and pets while offering smooth, one-hand operation. The internal spring-loaded mechanism has passed thousands of lift cycles; you can stop the shade at any position, and its rebound speed and stop point are adjustable.

• Cordless operation reduces entanglement hazards in homes with kids or pets.
• Spring mechanism tested for durability and smooth travel.
• Adjustable rebound speed and stopping position via accessible screws.
• Simple one-hand pull and gentle close for controlled movement.

What do I get in the box, and how simple is installation?
