Our Picks: Best Up And Down Window Shades reviews
1. LazBlinds No-Drill TDBU Cellular Shades: Best for Tool-Free Setup
This LazBlinds shade is designed for people who want top-down/bottom-up control without drilling holes. Its spring tension rod is intended to fit inside the window frame, and the cordless rails can be moved to let light in from above, below, or both directions. That makes it a useful option for rooms where you want daylight but also want to limit direct views inside.
The cellular fabric has a honeycomb structure intended to help insulate the window and reduce outside noise. However, the product description uses both “light filtering” and claims about a silver-plated layer blocking sunlight. Those terms can mean different things in practice, so check the exact fabric option and listing details if you need a particular level of darkness.
The listed shade is 33 5/8 inches wide for a 34-inch window, and the spring rod is adjustable. Measure the narrowest part of your frame and compare it with the stated fit range before ordering. A tension-fit shade can be convenient for a rental, but it still depends on a compatible, stable window opening.
Pros:
- Tool-free installation is designed to avoid screws and drilling.
- Cordless top-down/bottom-up rails allow flexible light and privacy control.
- Honeycomb cells are intended to provide thermal and noise insulation.
- Specified fit range offers some flexibility around the listed window width.
Cons:
- The product description mixes light-filtering and strong light-blocking claims, so confirm the fabric version.
- Fit depends on the window frame being within the stated tension-rod range.
Verdict: Choose this LazBlinds model if you want cordless TDBU control and a no-drill installation, but verify both the window measurements and the fabric’s light-filtering level first.
2. SUNFREE TDBU Cellular Shades: A Compact Cordless Option
The SUNFREE shade is a fixed-size cordless cellular model measuring 22 by 36 inches. Its top-down/bottom-up design gives you three basic positions: lower the top, raise the bottom, or adjust both to control how much of the window is covered. That flexibility can be handy in an office, bedroom, or living room where light and privacy needs change during the day.
The listing describes the honeycomb shade as blackout and says its inner layer is intended to reduce light, noise, heat, and UV exposure. It also includes hardware for inside- and outside-mount installation. For an inside mount, the listed guidance calls for a shade width about half an inch narrower than the window; an outside mount should extend beyond the window for better coverage.
This model is less flexible than a custom-size option, so measure carefully before buying. Its fixed dimensions make it a sensible candidate for a smaller window that closely matches the listed size, but it may not work for wider or taller openings.
Pros:
- Cordless rails can stop at different positions.
- TDBU operation supports daylight while keeping some of the window covered.
- Mounting hardware is described for both inside and outside installation.
- Honeycomb construction is intended to help with insulation and light blocking.
Cons:
- The listed 22-by-36-inch size limits its fit to appropriately sized windows.
- Measure for the mount style you plan to use; the recommended allowances differ.
Verdict: The SUNFREE is worth considering for a smaller window that matches its dimensions and where cordless adjustment and stronger light blocking are priorities.
3. Changshade Custom No-Drill TDBU Shades: Best for a Tailored Size
Changshade’s cellular shade is aimed at shoppers who need more than a standard size. The listing describes custom sizing, with the maker confirming dimensions by email before production. That extra step can help when your window does not match a ready-made shade, but it means you should provide careful measurements and review the confirmation before the order is finalized.
The no-drill design is promoted as a quick installation that leaves the window frame untouched. Its TDBU rails allow you to adjust light and privacy from either end, while a silver-plated inner layer is described as blocking sunlight and UV rays. The cellular construction is also intended to help with insulation. These features make the shade a possible fit for rooms where daytime darkness or privacy matters.
Unlike the fixed-size picks, this model’s main advantage is the ability to request a tailored size. The product description does not provide a specific standard dimension or detailed measurement rules, so confirm how to measure, what sizes are supported, and how the no-drill mount fits your particular frame before ordering.
Pros:
- Custom sizing can suit windows that do not match common dimensions.
- No-drill installation is designed to avoid damage to the frame.
- TDBU control lets you adjust coverage from the top or bottom.
- Blackout-oriented fabric and cellular construction are intended for light control and insulation.
Cons:
- Custom orders require accurate measurements and confirmation before production.
- The listing details provided do not specify a standard size or full fit range.
Verdict: Consider Changshade if standard dimensions do not fit your window and you are comfortable confirming custom measurements before the shade is made.
4. Allesin Cordless Cellular Shades: Best for a Larger Honeycomb Structure
Allesin’s 27-by-64-inch cellular shade combines cordless TDBU operation with 1.5-inch honeycomb cells. You can move the top or bottom rail to manage privacy and incoming light without a hanging cord. The product description also calls out aluminum alloy top and bottom rails, which are intended to provide a sturdy frame for regular adjustment.
The shade’s cellular structure and silver-plated inner layer are described as helping reduce heat transfer, noise, sunlight, and UV exposure. These features may be useful for a bedroom, office, or window facing a busy area, though the listing does not promise that the shade will eliminate all outside noise or light around the edges.
For an inside mount, the listing requires at least 2 inches of frame depth and recommends ordering a shade slightly narrower than the smaller of the top and bottom frame measurements. Outside mounting calls for extra width and length. Those instructions make measuring especially important; the listed 27-by-64-inch product is not a one-size-fits-all option.
Pros:
- Top-down/bottom-up cordless control provides flexible coverage.
- 1.5-inch honeycomb cells are designed for thermal insulation.
- Aluminum alloy rails are described as rust-resistant and sturdy.
- Listing provides separate measurement guidance for inside and outside mounts.
Cons:
- Inside mounting requires at least 2 inches of frame depth.
- The listed dimensions may not suit windows outside its size range.
Verdict: Pick the Allesin if its dimensions fit your window and you want cordless TDBU operation with a larger honeycomb structure and metal rails.
5. LazBlinds Blackout TDBU Shades: A No-Drill Pick for Bedrooms
This LazBlinds model pairs blackout fabric with cordless top-down/bottom-up control. You can lower the top rail to bring in daylight while leaving the lower part covered, or raise the shade from the bottom to uncover more of the window. That makes the design more flexible than a shade that only moves as one piece, especially when you want light without opening the full window to view.
The listing describes a silver-coated inner layer and 1.5-inch honeycomb cells intended to block light through the fabric and help insulate against heat and cold. A tension mount is designed for tool-free installation inside the frame. The stated fit is for a 34-by-48-inch window, with an actual shade width of 33 5/8 inches and a spring rod that adjusts within a specified range.
One important limitation is availability: this item is marked unavailable in the supplied product information. If it becomes available, confirm the tension-fit range and remember that blackout fabric does not necessarily mean there will be no light around the shade’s edges.
Pros:
- Blackout fabric is suited to rooms where limiting light is important.
- Top-down/bottom-up movement allows daylight from above while retaining lower coverage.
- No-drill tension mounting avoids permanent holes when the fit is suitable.
- Honeycomb cells are intended to help insulate against heat and cold.
Cons:
- The listing is marked unavailable in the supplied product information.
- The fixed size and tension-rod range require a close measurement match.
Verdict: This is a promising blackout-style option for a bedroom or media room if it is available and your window matches the stated tension-fit range.
How to Choose Up-and-Down Window Shades
Decide How Much Light You Want to Block
Light-filtering fabric softens incoming daylight while preserving a brighter feel. Blackout-oriented fabric is designed to block light through the material, which can be useful in bedrooms or media rooms. The shade’s edges may still allow some light through, so consider how closely it fits the frame and whether the product includes any separate light-blocking features. Read the fabric description carefully, especially when a listing uses both light-filtering and blackout language.
Choose the Right TDBU Operation for Your Room
Top-down/bottom-up control lets you lower the top rail, raise the bottom rail, or position both to suit your needs. Lowering the top can admit daylight while the lower part of the window remains covered. Raising the bottom can uncover a view while leaving the upper portion shaded. Think about which direction you are most likely to use, and check that the product’s rails are designed to move independently.
Measure for Your Mounting Style
Measure the window carefully before selecting a size. For an inside mount, check the frame width at more than one point, use the narrowest measurement when the product instructions call for it, and confirm the available depth. Outside mounts usually need extra width and length to cover more of the window. Follow the specific sizing guidance for the shade you choose rather than assuming all brands use the same deductions.
Compare Installation Methods
A no-drill tension mount can be useful when you want to avoid making holes, but it must fit securely within the window opening. Check the product’s stated width range and the types of surfaces or frames it supports. Other shades use included mounting hardware and may require a different setup. Choose the installation style that works with your window and your comfort level with mounting hardware.
Consider Cellular Construction and Materials
Cellular shades use honeycomb-shaped cells, and the products here describe those cells as helping with insulation. Cell size, fabric, and inner layers differ between models, so compare the details rather than assuming all cellular shades perform the same way. Also look at the rail material and the shade’s cordless design if you expect to adjust it often.
Check Whether the Size Is Standard or Custom
Fixed-size shades can be straightforward if your window closely matches the listed dimensions. A custom-size shade may suit an unusual opening, but it requires precise measurements and careful confirmation of the order details. Before choosing a custom option, make sure you understand how the manufacturer wants the window measured and what fit range the finished shade supports.
Frequently Asked Questions
What does top-down/bottom-up mean?
It means the shade can be adjusted from both the top and the bottom. You can lower the top rail to let light in while keeping the lower part covered, raise the bottom to uncover more of the window, or position both rails to choose how much of the window is shaded.
Are cordless up-and-down shades a good choice for homes with children or pets?
These picks use cordless designs, so they do not have dangling lift cords. That can help keep the window area tidier. Follow the manufacturer’s installation and use instructions, and check the product details for the safety information relevant to your home.
Do cellular shades block all light?
Not necessarily. Some fabrics are described as light filtering, while others are marketed as blackout or light blocking. Even with blackout fabric, light may enter around the sides if the shade does not cover the window opening closely.
Can I install a no-drill shade in any window?
No-drill designs still need a compatible frame and a secure fit. Check the shade’s width range, installation requirements, and supported surfaces before ordering. A window outside the stated fit range may not hold the shade properly.
How do I measure for an inside mount?
Measure the inside width of the frame at the points specified by the product instructions, and check the frame depth as well. Some listings ask you to use the narrowest width and subtract a small amount for clearance. Use the exact measurement method provided for your chosen shade.
Should I choose a fixed-size shade or a custom-size shade?
A fixed-size shade can work well when its listed dimensions match your window and mounting style. Custom sizing is useful when standard dimensions do not fit, but you need to provide accurate measurements and verify the final size before the order is made.
Final Recommendation
For a tool-free installation and flexible cordless control, the LazBlinds no-drill shade is a strong starting point, provided its fit range matches your frame and you confirm the fabric option. The SUNFREE is a more compact fixed-size choice, while Changshade offers a custom-sizing route for less common windows. Consider Allesin if its dimensions and depth requirements suit your frame, or the blackout LazBlinds model if it becomes available and you need a darker fabric. In every case, measure first and choose the light level that fits the room.
