SBARTAR Cordless Light-Filtering Shade
This SBARTAR shade is best for buyers who want light filtering, privacy, and cordless operation in one cellular shade. Its polyester fabric is described as filtering harsh sunlight into a softer glow while providing privacy. The listing says the honeycomb cells trap air and may help maintain room temperature and reduce noise.
For outside mounting, the seller recommends choosing a shade about 4 inches wider than the window. That added width is intended to cover more of the surrounding area. The cordless design operates by pushing or pulling the bottom rail and avoids dangling cords, a consideration for homes with children or pets.
Why it was selected: The listing explicitly covers outside mounting, light filtering, and cordless operation. Limitation: The recommended 4-inch width addition is seller guidance; measure the actual coverage area and confirm the available size before ordering.
SBARTAR 24 × 36-Inch Light-Filtering Shade
This fixed-size SBARTAR option is best for buyers whose window treatment needs match the listed 24-inch width by 36-inch height. The polyester cellular fabric is described as filtering daylight while maintaining privacy. The listing also says its honeycomb construction can trap air and help with room temperature and noise reduction.
It supports inside or outside mounting. For outside mount, the seller recommends a shade width approximately 4 inches wider than the window. For inside mount, the stated guidance is to order 0.25 inch narrower than the window opening, with at least 2 inches of depth required. Installation is screw-mounted.
Why it was selected: It provides clearly stated dimensions and mount-specific measuring guidance. Limitation: Its listed 24 × 36-inch dimensions may not suit windows that need a different coverage size; verify fit before purchase.
BlindsAvenue Cordless Cellular Shade
The BlindsAvenue shade is best for shoppers who want precise ordering instructions for a standard-size shade. It is listed as white, cordless, and made from 100% polyester, with a stated size of 24 inches wide by 48 inches high.
For outside mounting, the seller says to order a shade matching the width of the area to be covered. This makes the coverage measurement—not simply the glass width—the key figure to determine. For inside mounting, the listing says to order ¼ to ½ inch narrower than the opening and identifies a 24¼- to 24½-inch window opening as the fit range for this shade.
Why it was selected: The listing distinguishes outside- and inside-mount ordering clearly. Limitation: The specific fit range provided is for inside mounting; outside-mount buyers must measure their desired coverage area.
Boolegon Custom-Size Blackout Cellular Shade
This Boolegon product is best for shoppers specifically looking for a black, custom-size blackout cellular shade. The product name identifies its blackout style and custom sizing, making it a possible choice when light control and a tailored size are the main priorities.
Why it was selected: Its stated blackout format and custom-size description address needs that differ from the light-filtering options above. Limitation: The supplied product information does not provide measuring instructions, material details, operating style, or mount requirements. Confirm those details in the listing before choosing it for an outside mount.
LazBlinds Cordless Cellular Shade
The LazBlinds shade is best for buyers seeking the listed 20-inch-wide by 64-inch-high taupe cordless cellular option. Its product name identifies cordless operation, while the provided details establish its color and dimensions.
Why it was selected: It gives shoppers another stated size and color to compare against the white options. Limitation: No mounting, fabric, light-control, or measuring information was supplied. Check the current listing for those specifications and confirm that the size covers the intended outside-mount area.
Buying Guide: Choosing Outside Mount Cellular Shades
How should you measure for an outside mount?
Measure the full area you want the shade to cover, including any extra width needed beyond the window opening. The BlindsAvenue listing says to order a width matching the desired coverage area. SBARTAR recommends adding about 4 inches to the window width for outside mounting. These are product-specific instructions, not a universal sizing rule, so follow the chosen shade’s guidance and account for nearby walls, trim, and hardware.
Should you choose light filtering or blackout?
Light-filtering shades soften incoming daylight while aiming to preserve privacy, according to the SBARTAR listing. A blackout style, such as the Boolegon product name indicates, is intended for shoppers prioritizing darkness. The supplied Boolegon details do not explain its performance or installation, so confirm the listing specifications if darkness is essential. Neither category should be assumed to block every edge gap when mounted outside.
Is cordless operation important?
A cordless design can be useful when you want to avoid dangling cords. The SBARTAR cordless listing describes operation by pushing or pulling the bottom rail and calls out children and pets as a consideration. The LazBlinds product name also identifies it as cordless, but the supplied details do not explain its operation. Compare control method and shade size before ordering.
What should you verify before checkout?
- Confirm the shade width and height match the intended coverage area.
- Check whether the selected size is fixed or custom.
- Verify that the listing supports outside mounting and provides appropriate hardware or instructions.
- Choose a light-filtering or blackout style based on the room’s light-control needs.
- Review color and operating details; do not assume specifications missing from the product description.
Frequently Asked Questions
What is an outside mount cellular shade?
It is a cellular shade installed outside the window opening to cover the opening and, if desired, part of the surrounding area. Measure the coverage you want rather than relying only on glass dimensions.
How much wider should an outside mount shade be?
It depends on the product and desired coverage. SBARTAR recommends about 4 inches wider than the window, while BlindsAvenue advises ordering to match the width of the area to be covered.
Do cellular shades provide privacy?
The SBARTAR light-filtering shades are described as filtering daylight while maintaining privacy. Check the particular listing for its fabric and privacy details.
Can I use an inside-mount shade outside the window frame?
Some listed shades support both mounting methods, but sizing guidance differs by mount. Check the selected product’s outside-mount instructions rather than applying its inside-mount measurements.
Are all cellular shades cordless?
No. Cordless operation is specified for the SBARTAR and BlindsAvenue products described here, and in the LazBlinds product name. Confirm the operating style for any other model before ordering.
