Top Down Bottom Up Cellular Shades: Is the Upgrade Worth It for Street-Facing Maryland Homes?

If you already feel the daily dilemma in your living room window (do you open the shades or do you lose the daylight and also all the pedestrians staring in your window?), in front of the neighbors driveway, or in your bedroom where you can hear everyone come and go, then you already know the trade-off.

Top Down Bottom Up Cellular Shades get the job done precisely. They’re more expensive than a typical shade, and homeowners in rowhouse communities, townhome communities and street-facing colonials all over Maryland are starting to ask the same question before purchase: is it worth it, or a gimmick?

It provides a simple answer: based on actual prices and actual trade-offs, and an honest assessment of what Maryland homes will gain from the upgrade.

What Are Top Down Bottom Up Cellular Shades?

A normal cell shade only comes up from the bottom – to allow light, you must open the whole window from the bottom up. Often called TDBU shades, top down, bottom up cellular shades allow you to move the top and the bottom of the shade separately.

In reality, this can be used to make the top of the shade shorter to obscure direct eye-to-eye street views from the house and the lower portion longer to allow more light into the home, or vice versa – lower the bottom of the shade for light and raise the top for privacy at the higher part of the window. You have full control of what portion of the window is obscured at any point in time.

The light and privacy control is also enhanced by the air being trapped within the cells of the pleated cellular structure, which is also what makes the pleats so distinctive.

Why Street-Facing Homes Are the Ideal Use Case

This is not a feature that is equally applicable to all rooms. What Windows TDBU really does well is where they are used in a window where eye-level privacy is required, and daylight is equally demanded, and that’s a fair amount of the street-facing homes in the DMV.

Consider a typical row house in Silver Spring or a town home in Columbia with a front window a few feet away from the sidewalk. If you use a standard shade, you’re left with a dark living room or fishbowl. A TDBU shade will allow you to block the view from the street and yard while allowing natural light to enter the living space through the lower portion of the shade.

This is the time when the upgrade is most needed. In rooms that lack privacy, such as those located on the north side of the house, or upstairs bedrooms in rooms where there is no ground-level noise from foot traffic, the privacy benefit is much less valuable – and a regular cellular window shade will do the same job for much less cost.

How Much More Do Top Down Bottom Up Shades Actually Cost?

This is the most important question and unfortunately, the answer is 20-40% more than a single-direction cellular shade, as the dual-rail hardware and mechanism necessary to operate in both directions adds to the cost.

Custom cellular shades can cost anywhere from about $55 to $120 per shade, depending on the type of cells, fabric density and window size. The top down bottom up feature on top of that will usually cost you a moderate premium on a per window basis, and if you are already in the market for a shade that is a cellulose or woven wood, it will likely be a sensible add-on instead of an extra major expense.

There are a few elements that affect the overall cost of a Maryland home:

• Cell structure – Single-cell shades are priced lower; double-cell shades (which provide up to 20% to 30% more insulation in summer heat and winter cold) are more expensive; and include a third layer of cells for extra privacy and security
• Fabric opacity – Light-filtering fabric is usually less expensive than the full blackout fabric and is more opaque
• Window size – if the windows are larger, they must be removed from the street side and if they are bay windows, they will cost more per shade
• Operating system – cordless TDBU shades are less expensive than corded shades, but are much safer for homes with children and pets, and look more streamlined and clean

If you have a two to three window living room that is facing the street, the total TDBU upgrade will increase your project cost by a moderate amount when compared with regular cellular shades – a worthwhile upgrade for most homeowners who want privacy and daylight in the same room.

The Real Benefits – Beyond Just Privacy

1. Daylight Without Compromise

The greatest benefit is that you don’t have to sacrifice privacy for the presence of natural light. This is beneficial for rooms with high foot traffic or adjacent structures, providing a peaceful and private setting with sufficient natural light. This is more important than one might think for Maryland homes that do not get much natural light during the winter.

2. Energy Efficiency on Top of Privacy

The honeycomb structure holds air to improve insulation over window areas, and double-cell designs can enhance window insulation by as much as 20–30% over single-layer fabrics. Not only are you getting privacy, but you’re getting a more energy-efficient window treatment than a blind or curtain – which is a big deal in Maryland’s humid summers and cold winters.

3. Fewer Window Treatments Needed Overall

While TDBU shades are generally more expensive than traditional blinds or roller shades, they can help to save on energy costs and eliminate the need for multiple blinds, such as pairing window blinds with curtains. For many homeowners who would otherwise want to add sheer fabric over blinds for this effect, one TDBU cellular shade does the same in one product.

4. Child and Pet Safety

Most modern top down bottom up shades are cordless operating systems, meaning that there is no risk of a dangling cord, which is important for Maryland families with young children or pets in the household.

5. Works Well for Specialty and Difficult Windows

Standard rectangular windows are not the only windows that can be used with TDBU functionality. Window shades are also available in a cellular option that can be customized to fit any special window shape, such as skylights, arches and angled windows, providing an ideal fit and seamless integration – a good fit even for bay windows or architectural windows often seen in older Maryland neighborhoods.

The Honest Drawbacks

Any upgrade will have its pros and cons, which should be included in a fair buying guide.

Higher cost. You are paying a premium, indeed, for the dual-rail mechanism, as mentioned above. If you’re on a home budget that is short on cash and you don’t live on a busy street, you might want to invest it elsewhere.

More frequent adjustment. Shades of this type are also known as TDBU and provide more control, so many homeowners tend to adjust them more frequently during the day than they would a standard shade – a good thing for functionality, but a point to consider if you want something set and forget.

Slightly more moving parts. While it does have two instead of one rail, there is slightly more hardware that may at some point require a tweak or repair, but quality cellular shades from reputable manufacturers are designed to handle years of daily use without any problems.

Installation precision matters more. The shade is adjustable from both ends so it is essential to get the measurement right – if it is just a little out, it may bind or create a gap in the upper or lower edge. It’s one of the best reasons to have TDBU shades professionally sized and fitted instead of trying it at home.

Real Buyer Feedback

Property owners making the transition all agree to the same result. One reviewer mentioned the ability to shade-off the window to keep neighbours out of the view while enjoying their view, which is exactly what street facing Maryland homes would like to solve. A particular homeowner really pointed out that they loved the ability to let light stream in from the top of the window without lighting up the entire window, which was great for privacy.

Our Verdict: Who Should Upgrade?

Consider upgrading to top down bottom up cellular shades if:

• Your window is very close to a street, sidewalk, shared driveway, or neighbouring property
• Layered curtains over blinds, just to achieve privacy without sacrificing natural light
• A room you use a lot during the day (living room, kitchen, home office)
• You are looking for an extra energy efficiency boost in addition to privacy control
• Do you have kids or pets and want a cordless safe system to operate? 

Stick with standard cellular shades if:

• No direct outside view from your window (upper floors, room facing, fenced backyards)
• Budget is the main criterion, and the window in question is not high priority
• You rarely change your window treatments during the day, and you like things to be simple

For most of the street side row houses, townhouses, and close-set suburban colonials in Maryland, the improvement is a worthwhile investment. The extra expense is actual, but so is every day when you have to choose between a dark room and an exposed room – and TDBU shades actually remove that dilemma.
