Expert Cellular Shades for Westfield Homes

Cellular is the one product on this list with published test data behind it. Department of Energy and Oak Ridge National Laboratory testing found cellular shades saved up to 20 percent on heating energy and up to 15 percent of total heating and cooling energy against a bare window, measured at an ORNL test house and modeled across fifteen climate zones. That's a measured result rather than a promise about your utility bill, and it's worth knowing what it comes from before anybody quotes you a number.

It matters here because central Indiana genuinely has both loads. January averages a low of 20.9F over a cold season of about three months, and July averages a high of 85.2F over a muggy season running from late May to late September. A single product being defensible on both seasons is unusual, and the honeycomb structure is why: the cells trap a still air layer against the glass, which works the same way regardless of which direction the heat is trying to go.

In a Westfield house the second reason to choose cellular is usually top down bottom up. Lot sizes in the production communities run tight, 0.10 to 0.40 acres in Harmony and Centennial, so front rooms sit close to a sidewalk and a street. Dropping the top of a shade rather than raising the bottom gives you daylight across the ceiling and privacy at eye level, which is exactly the problem on a narrow lot. It puts a second operating system on every shade, so it costs more, and on the right window it's the reason the product wins.

When to Call

Signs You Need Cellular Shades

If you notice any of these in your Westfield home, it is worth booking a measure. None of it is urgent, and none of it fixes itself either.

A bedroom feels cold near the glass in January

A front room needs privacy without losing daylight

You want measured energy performance rather than a claim

Stack height is tight above a tall narrow opening

The room gets both a heat and a draft complaint

A nursery needs darkness and a soft product

Existing pleated shades have gone limp and dusty

Two seasons are both a problem in the same room

Our Process

How Westfield Window Treatments Handles Cellular Shades

Every job follows the same six-step process. Transparent, thorough, and done right the first time.

1

Establish which season

The first question is whether the complaint is winter cold near the glass, summer heat, privacy, or all of them. Cellular answers all four to different degrees and the answer changes the cell count and the fabric tier. A room with a genuine winter problem gets double cell. A room where privacy is the actual driver gets a different fabric and possibly top down bottom up.

2

Choose single or double cell

Single cell is the base and it's plenty in a room that's simply bright. Double cell traps more air and does more against a 20.9F night, at more cost and more stack. We say plainly which rooms justify it rather than upselling the whole house, because in a bedroom that faces east and never gets cold the second cell is money doing nothing.

3

Check stack height

A cellular shade stacks at the head and that stack has real depth, more on a double cell and more again on top down bottom up. On a tall narrow opening, or where the head of the opening is close to the ceiling, the stack can cover glass you wanted. We measure the stack allowance against the actual opening and show you where the top of the glass ends up.

4

Decide the operating system

Cordless lift is the default and the right answer in any room a child uses. Top down bottom up adds a second system and a second set of hardware. Motorization is worth pricing where a shade is high, where there are many of them, or where grip strength is a consideration. Each of those changes the head detail, so it gets settled before fabrication.

5

Warn about condensation

Winter condensation on glass wicks into fabric hems and cell walls, and it's worst behind blackout linings and tight side channels. A house finished this year is still drying out through its first heating season, which makes this a live issue across a lot of Westfield. We say where an inside mount raises the risk and what mounting or venting reduces it.

6

Install and check the drop

Brackets level across the run, full lift and full drop tested several times, and the bottom rail checked parallel to the sill. On top down bottom up we run both systems through their travel with you watching, because the middle rail position is the thing people fiddle with and the thing that gets reported as a fault when it's actually adjustment.

Scope of Work

What Cellular Shades Includes

Every Westfield job is documented item by item. Here is what the crew covers.

Room-by-room walk to decide where the energy case is real and where it isn't

Three widths and three heights per opening with a diagonal square check

Mounting depth measured so the headrail sits fully inside the opening where an inside mount is wanted

Single cell or double cell specified per room rather than picked once for the whole house

Cell size chosen against the opening, smaller cells on short windows so the stack stays in proportion

Light filtering, room darkening and blackout fabrics separated in writing before anything is ordered

Top-down bottom-up specified where street privacy and daylight both matter at the same window

Cordless lift specified as the default in bedrooms, nurseries and stairwells

Continuous cord loop with a tensioner used only where weight or height makes cordless impractical

Products specified to conform to ANSI/WCMA A100.1-2022 for cord access

Winter condensation risk on tight inside mounts explained at the measure

Headrail clearance from the glass checked so the shade isn't sealed against a cold surface

Light gap per side disclosed for inside mounts and written on the paperwork

Vertical cellular units drawn where the opening is a slider rather than a window

Specialty shapes measured with a template where an opening is arched or angled

Wide spans reviewed for headrail deflection and split into two units where that's the right call

Bottom rail leveling and full travel tested at every unit on install day

Old product removed, brackets pulled and the wall left ready for the new mount

Pricing

What Cellular Shades Cost in Westfield

National category numbers put stock shades around $60 to $600 per window and custom-fabricated shades around $250 to $2,600 per window. They're national ranges, published for the category, and they aren't a quote for any address in Westfield. Cellular sits across a wide part of that band because the construction varies so much. A single cell light filtering shade on a small opening is near the bottom. A double cell blackout shade with top-down bottom-up on a tall window is near the top, and it should be, since you're paying for two lift systems and a heavier fabric. Size, cell count, fabric opacity and lift type are the four levers. Westfield Window Treatments prices from measured openings in Hamilton County, not from a per-window average.

By Product

How Cellular Shades Differ by Product

Every product in this trade behaves differently in a room. Here is what that means for this work.

Single cell, 3/8 inch: The small cell keeps the stack tight at the top of the window, which matters on short openings and transoms. Specify it where you want the shade nearly gone when it's raised and the room isn't an energy problem.

Single cell, 9/16 inch: The everyday size. It gives you real cell depth without a heavy stack, and it covers most bedrooms, living rooms and offices. This is the default we start from unless a room argues for something else.

Double cell, 3/8 inch: Two rows of cells means two pockets of trapped air across the same opening. Choose it on the elevations that get hit hardest, which around here usually means the north wall in January and the west wall in July.

Double cell, 3/4 inch: The deepest construction we normally hang. It stacks taller and costs more, so we reserve it for tall windows on hard elevations where the energy argument does the work of justifying it.

Light filtering fabric: Daylight comes through diffused and the room stays bright without direct glare. It's the right call in kitchens, living rooms and any space where you want softness rather than darkness.

Room darkening fabric: A denser fabric, sometimes with a liner inside the cell, that cuts most of the light through the face. Bedrooms are the obvious use. Understand that an inside mount still passes light at the edges.

Blackout fabric: The heaviest option, with a light-blocking liner in the cell. Pair it with an outside mount or side tracks if the goal is a genuinely dark room rather than a dim one. On its own it darkens, it doesn't seal.

Top-down bottom-up: Two rails on independent controls, so you can drop the top for daylight while the bottom stays up for privacy. It earns its cost in bathrooms and in any room facing a sidewalk or a close neighbor.

Cordless lift: No lift cord anywhere on the shade. It's what we put in kids' rooms by default, and it's the cleanest thing to operate on a shade you touch every day. Wide units want a hand at each end of the rail.

Vertical cellular: The same honeycomb fabric running on a track for a patio slider, stacking to one side. It gives a sliding opening the insulating construction that a vertical blind can't, and it looks like fabric rather than hardware.

Light Control

See What Each Fabric Does To The Light

Pick a fabric below and the window updates. It's a drawing rather than a photograph, so read it as a rough guide to what each family does in a Westfield room, and to what it doesn't do.

Fabric type

Sheer, 10 percent openness

Ten percent of the weave is open, so you keep the view and most of the daylight. Glare drops a little. After dark, once your lamps are on, someone outside can read shapes through it, which is why this belongs on a view window rather than a bedroom.

Openness factor is printed on the fabric card, so you can compare one line against another before you order anything.

Keeps the viewNot private after dark

Solar, 5 percent openness

The usual pick for a west window or a covered porch. You can still read the yard through it, glare comes down noticeably, and the fabric intercepts a good share of the sun before it reaches you at four in the afternoon.

It also cuts the UV landing on floors and furniture. NFRC puts UV at roughly 40 to 60 percent of fading damage, so this slows fading rather than stopping it.

View and glare controlSlows fading

Solar, 3 percent openness

A tighter weave. The room goes dimmer and the view drops back to an outline. Choose it where the sun is the problem and the view is second, which around here usually means a west wall in July. That's a common call on this side of Indianapolis.

Openness affects how much you see out, not how private you are. A 3 percent fabric still shows silhouettes at night.

View becomes an outlineStrong glare control

Solar, 1 percent openness

Close to a solid fabric with a little view left in it. This is the strongest glare control in the solar family.

The trade is that it darkens the room on a gray January day too. Indianapolis averages a January high near 36F and the light is flat, so think about how the room reads in both seasons before you commit.

Darkest solar optionDim on gray days

Light filtering

No view through it. Daylight comes through the face diffused, so the room stays bright without a hot spot across the television or the kitchen island. This is the default for living spaces.

It isn't private in reverse at night. With the lamps on and the sun down, silhouettes still show.

No view through itBright without the glare

Room darkening

A denser fabric, usually with a liner behind it. Most of the light coming through the face is gone.

Light still arrives around the edges on an inside mount, so a room darkening shade gives you a dim room rather than a dark one. If someone in the house sleeps during the day, say so at the measure and we'll scope it differently.

Dim, not darkEdges stay bright

Blackout

The fabric itself passes essentially no light. What you'll still see is the perimeter. Lutron publishes an inside-mount light gap of about 3/4 inch per side on its Roller 20 and 64 shades, along with a standard factory deduction of 1/16 inch per side, and shades over 120 inches tall or past a 4:1 height-to-width ratio get larger gaps than that.

So if you need a genuinely dark bedroom, that gap has to be dealt with on purpose, either with side channels or by going outside mount. We tell you which one your opening can carry while we're still standing in the room.

Dark facePerimeter needs a plan

Openness factor is a measured fabric spec, so you can compare it line to line. The category names are not measured. One maker's room darkening can behave like another maker's light filtering, which is why the sample books come to the measure and get opened in the room they're going in, at the hour that room has the problem.

Common Questions

Cellular Shades FAQ

Questions we hear most often from Westfield homeowners considering cellular shades.

Nobody can honestly tell you a figure for your house, and anyone who does is guessing. What exists is measured testing: DOE and Oak Ridge National Laboratory found up to 20 percent heating energy saved and up to 15 percent of total heating and cooling energy against a bare window, at an ORNL test house in Knoxville with results modeled across fifteen climate zones. Your result depends on the window, the room, the exposure, how the house is run and how often the shades are actually closed. Treat it as evidence the product does something real, not as a number to put in a budget. The measured benefit also assumes the shade is closed, and one left open all winter for the view does nothing.
Double cell traps more air and does more thermally, at higher cost and a taller stack at the head. It's worth it in rooms with a real winter complaint: a bedroom where the glass feels cold, a bonus room over a garage, a room with a lot of north or west glass. It isn't worth it in a hallway, a room that's rarely used, or a room where the actual problem is glare rather than temperature. We'd rather specify double cell in four rooms and single in the rest than sell double cell across a whole house. Double cell also stacks deeper at the head, so on a short opening with little room above the glass the second cell can cost you visible daylight.
It lets the shade drop from the top as well as rise from the bottom, so you can cover the lower half of a window and leave the top open. In Westfield's production communities, where lots run 0.10 to 0.40 acres and front rooms sit close to the street, it's the specification that gets you daylight and privacy at once. It's not free: it adds a second operating system, more hardware and a deeper stack. In a rear facing bedroom nobody can see into, it's an expensive feature you'll use twice. It also changes how a room feels rather than just how private it is, because daylight arriving high and bouncing off a ceiling reads very differently from daylight at eye level.
Blackout cellular fabric blocks light through the fabric, and the shade still lets light in around the edges on an inside mount. That's a mounting fact rather than a fabric one. If darkness is the requirement, the honest specification is an outside mount with overlap, or an inside mount with side channels and a light blocking pocket at the head. There's a second consideration specific to cellular: the cord holes through the cells transmit tiny points of light on a blackout fabric, visible in a genuinely dark room. Cordless construction avoids that. In a nursery specifically, we'd rather specify the mount that genuinely darkens than sell a blackout fabric that leaves two bright lines on the wall at five in the morning.
Cell walls delaminating at the cord holes is the material failure, and it happens where the fabric has taken a lot of cycles or a lot of sun. The mechanical failure is more common: cordless spring tension drifting so the shade creeps down or won't hold position, because the constant force spring was sized to the fabric weight and the fabric relaxes over time. That's the highest volume warranty item in this trade across all products, not just cellular. Both are worth knowing about before you buy, and both are usually covered by the manufacturer's warranty terms. Both failures show up sooner on a shade that runs several times a day, so a hallway shade nobody touches will outlive a kitchen shade of the same age.
It can, and this is the one to plan for in a new Westfield house. Winter condensation forms on the glass, and on an inside mount the fabric hem and the lower cells sit right against it. Moisture wicks in, and what you see is dark spotting along the bottom rail, sometimes a musty smell, and staining on the room side. It's worst behind blackout linings and tight side channels where air can't move. A house in its first heating season is still releasing construction moisture, which makes the first winter the riskiest one. Cracking a window occasionally on a cold dry day, or raising the shade for an hour in the morning, does more to prevent it than any product choice will.
They're often the best option, and the reason is stack. A tall narrow stair opening has a lot of drop and very little forgiveness at the head, and a cellular shade stacks tighter than most alternatives at the same drop. The caution is operation. Nobody reaches a stair hall shade by hand, so it's either motorized or it's decoration that stays where it was left. On a two story stair wall in the newer Westfield stock, we'd price it motorized from the start. Stack height is worth measuring against the actual opening rather than a specification sheet, because the published stack for a product line assumes an average drop rather than yours.
Yes, and the specification matters more than the fabric name. Room darkening cellular in a cordless construction avoids the pinpoints of light that cord holes create, and the mount decides whether the room is actually dark. Inside mounted, expect light down both sides. Outside mounted with overlap onto the wall, or inside mounted with side channels, you get the result parents actually want. Cordless is the only sensible lift choice in a child's room regardless, and that's a safety point rather than a preference. Cordless is also the safer answer as the child grows, since a cord that's out of reach at six months is very much within reach at three years.
There's real testing behind the claim, and it deserves to be quoted accurately. Department of Energy and Oak Ridge National Laboratory work found cellular shades saved up to 20 percent of heating energy, and up to 15 percent of total heating and cooling energy, measured against a bare window. Two things matter in that sentence: it's against a bare window, and it's a ceiling rather than a promise. We won't turn those percentages into dollars for your house, because the honest conversion depends on your rates, your habits and your home.
Because we're in IECC Climate Zone 5A, which means a real heating load and a real cooling load in the same calendar year. January in the Indianapolis area averages a high near 36.1F and a low near 20.9F. July averages a high near 85.2F, with a muggy stretch running from late May to late September. Most window treatments earn their keep in one season. A cellular shade is doing something in both, which is why the payback conversation looks different here than it would in a mild climate.
Double cell puts two rows of trapped air across the opening instead of one, so it does more thermally and stacks taller when raised. Single cell costs less and keeps the stack tight. Our usual approach is not to buy the same thing everywhere. Put double cell on the elevations that actually punish you, the cold north wall and the hot west wall, and put single cell in the interior rooms and the hallway where the shade is really about privacy.
It's two rails on separate controls. You can pull the top rail down to let daylight into the upper part of the window while the bottom stays raised for privacy, or run it as a normal shade. It's worth it in a bathroom, in a front room facing a sidewalk, and in any room where you'd otherwise pick between light and being seen. It costs more because you're buying two lift systems, and it does add a little stack.
It can, and this is the disclosure people wish they'd had. A tight inside mount holds a layer of still air right against a cold interior surface. On a very cold January morning that surface can go damp, and the bottom rail or the fabric edge can pick up moisture. It's a comfort and maintenance issue rather than a defect. We mitigate it by keeping some clearance at the mount, and by raising the shade during the day so air moves across the window.
A little, over years, and it's manageable. Most of it stays near the openings at the ends. A vacuum brush across the face and a puff of compressed air through the cell ends handles a normal house. Don't submerge them, and don't scrub a light filtering fabric with anything wet, since water marks show on the face and don't come out. Blackout fabrics wipe more forgivingly because the liner is inside the cell rather than on the surface.
There is one, and it's the reason people occasionally feel misled after the fact. The shade has to be narrower than the opening to travel, so the factory takes a deduction and light comes in down each side. Lutron publishes 3/4 inch per side as a real figure on their roller product, and cellular behaves the same way. Tall shades leak more. If a bedroom needs to be dark, an outside mount that overlaps the trim beats an inside mount every time.
That's the reason cordless exists. A cordless lift has no accessible lift cord at all, which is exactly what the ANSI/WCMA A100.1-2022 work on cord access is about, and an inner-cord failure is treated as a substantial product hazard under 16 CFR 1120.3. We specify cordless as the default in any room a child uses in Westfield, and if a window is tall enough that cordless gets awkward, we look at motorization rather than putting a cord back into a kid's room.
Enough to plan for. A raised cellular shade compresses into a stack of folded fabric plus the headrail, and the taller the shade and the deeper the cell, the taller that stack. A tall double cell blackout unit takes noticeably more room at the top than a short single cell. If the view out the top of the window matters, we can mount above the opening on an outside mount so the stack sits on the trim rather than on the glass.
A bit, and less than the marketing suggests. The trapped air in a honeycomb absorbs some high-frequency sound, so a room with hard floors feels calmer with fabric across the windows. It does nothing meaningful about low-frequency traffic rumble, because that travels through structure rather than air. If sound is the actual problem, layering heavy drapery over the shade does more than upgrading the shade, and we'll tell you that instead of selling you a deeper cell.
Yes, with a template rather than a tape. An arch, an angled top over a stair or a trapezoid in a great room gets measured by making a physical pattern of the actual opening, because the geometry never matches what the plan says. Understand the tradeoff: most specialty shapes are stationary, so an arch fills the opening and stays there. If the shape has to operate, we look at splitting the opening into a fixed upper unit and a working lower unit.
Different jobs. A roller is a single layer of fabric and it's the better tool for glare control and view management, especially in a solar screen weave. A cellular is a folded structure with air inside it, so it's the better tool for comfort at the window in January and July. In a lot of Westfield houses the right answer is both, on different elevations, and occasionally both on the same window with a dual bracket.
Vertical cellular does. It runs the same honeycomb fabric on a track, stacking to one side, so a sliding opening gets an insulating fabric instead of hard vanes. It's worth measuring the stack width carefully, because the stacked fabric covers part of the opening and you don't want it landing over the door you actually use. We check which panel slides and set the stack on the fixed side.
Usually the lift, not the fabric. Cords inside the shade run through the cells and over pulleys, and after many thousands of cycles they wear. Cordless mechanisms lose a bit of spring tension over years, which shows up as a shade that creeps down slowly. Both are serviceable, and both are why we prefer brands that still sell parts years later. The fabric itself, kept out of direct water, generally outlasts the mechanism by a wide margin.
