Can Pleated Shades Be Blackout — The Liner Upgrade Guide
Authored By Michael Turner
Updated on May 12, 2026
⭐ Quick Answer — Can Pleated Shades Be Blackout?
- Yes — with a blackout liner: Any pleated shade can be upgraded to blackout by specifying a blackout liner at ordering. The liner blocks 100% of light through the fabric itself
- Three liner types: Privacy liner (~50–75% blocked, daytime privacy only) · Room-darkening liner (~85–99%, good for bedrooms) · Blackout liner (100% through fabric, shift workers and nurseries)
- Route hole warning: American Blinds specifically warns that “some light may shine through holes in the shade fabric.” Route holes where the cord passes through the fabric create pinpoints of light even with a blackout liner. Specify NeatPleat / hidden back-ladder construction to eliminate them
- Outside mount still required: The liner only addresses light through the fabric. Light also enters around the perimeter frame gap — specify outside mount (2–3 inches beyond the frame) to eliminate this
- Cordless conflict: Per Blinds.com — room-darkening liner is typically NOT available with cordless lift. If you want cordless AND maximum darkness — specify blackout liner (not room-darkening) and confirm compatibility
- Cost: Blackout liner adds $15–$35/window. Full blackout spec (liner + NeatPleat + outside mount) = $55–$90/window via SelectBlinds, Blindsgalore, or Graber
⚠️ The Complete Blackout Specification for a Pleated Shade — All 4 Elements Required: (1) Blackout liner — blocks 100% of light through the fabric. (2) NeatPleat or hidden back-ladder construction — eliminates route holes where the cord passes through the fabric (American Blinds warns these create pinpoints of light). (3) Outside mount — covers the frame perimeter gap on all four sides. (4) Cordless — confirm blackout liner (not room-darkening) is specified; per Blinds.com, room-darkening liner is often incompatible with cordless lift. Without all four — some light will still enter. See the full specification guide below.
💡 Bonded vs Sewn Liner — and the Value vs Blackout Cellular: Not all blackout liners are equal — a heat-bonded liner follows each pleat fold for continuous blackout; a sewn liner (attached only at edges) can separate at fold lines after 3–5 years of use, reducing performance. Ask the supplier which construction is used. And the value case: a complete blackout-specified pleated shade (blackout liner + NeatPleat + outside mount + cordless) costs $55–$90/window — significantly less than blackout cellular at $90–$150/window — with equivalent fabric opacity but without cellular’s insulation and sound benefits. See the full liner comparison below.

Yes, Pleated Shades Can Be Blackout — With One Important Caveat
The short answer is yes — any pleated shade can be upgraded to blackout performance by specifying a blackout liner at the time of ordering. The blackout liner is a dense, opaque backing material bonded or sewn to the back of the pleated face fabric. It eliminates light transmission through the fabric itself.
But American Blinds includes a specific warning in their pleated shade buying guide that no other competitor repeats — and it is the most important thing to understand before ordering:
“Be aware that some light may shine through holes in the shade fabric when lowered.”
These are route holes — small openings in the pleat fabric where the operating cord routes through the shade. Even with a blackout liner, the liner itself has matching holes at these cord routing points. Light can enter through these small openings and create pinpoints of brightness in an otherwise dark room.
The route hole issue matters most for:
- Shift workers sleeping in full daylight
- Nurseries where any light point can disturb an infant
- Home theaters where projected image contrast requires total darkness
The route hole issue matters less for:
- Standard bedrooms where sleeping occurs at night
- Rooms where night-time ambient light is minimal
- Any room where near-blackout (rather than absolute blackout) is sufficient
The Three Liner Types — What Each One Actually Does
This is the distinction no competitor guide explains clearly. Three liner options exist for pleated shades — and choosing the wrong one for your application is a common and expensive mistake.
Liner Type 1 — Privacy Liner (Light Diffusing)
Light blocking: Approximately 50–75% of incoming light What it does: Diffuses light that passes through the face fabric, making objects in the room appear as silhouettes from outside rather than as clear shapes. It does not block light. What you see inside: The room is noticeably dimmer but light still enters. At bright midday sun — the room has a soft, filtered appearance. Best for: Guest rooms and living rooms where daytime privacy is the goal but daylight is still wanted. Rooms where you want a “frosted glass” effect — visible from outside as a uniform surface, not as a window showing the room contents.
Liner Type 2 — Room-Darkening Liner
Light blocking: Approximately 85–99% of incoming light through the fabric What it does: Significantly reduces light transmission, making the room noticeably dark when the shade is lowered. A small amount of light still transmits through the liner at very bright conditions. What you see inside: A genuinely dark room — appropriate for sleeping. Some light may still be perceptible at the very brightest sun angles. Best for: Primary bedrooms for standard sleepers. Any room where good darkness is the goal but absolute blackout is not critical.
The critical specification conflict: According to Blinds.com buying guide, room-darkening liner is typically NOT available with cordless lift. If you want cordless operation AND room-darkening performance — you may be limited to blackout liner only, or to a corded room-darkening option. Confirm liner-and-lift compatibility with the specific supplier before ordering.
Liner Type 3 — Blackout Liner
Light blocking: 100% of light through the fabric itself What it does: Completely eliminates light transmission through the shade material. The only light that enters is through route holes and perimeter gaps — which require additional specification to address. What you see inside: Complete darkness through the fabric. Any remaining light comes from the perimeter edges (frame gaps) and route holes. Best for: Shift workers sleeping in daylight. Nurseries where infant sleep duration is the priority. Home theaters requiring projection contrast. Any room where maximum fabric darkness is required.
Per Graber Blinds: “Blackout — Eliminates outside light and prevents shadows or silhouettes from showing through, creating an ideal environment for rest, privacy, and screen visibility.”
The Route Hole Problem — And How to Minimise It
Route holes are the most underexplained limitation of blackout-lined pleated shades. Understanding what they are and how to address them determines whether the blackout liner delivers the darkness you expect.
What route holes are: As the operating cord raises and lowers the pleated shade, it must pass through the fabric at regular intervals. These pass-through points are the route holes. In standard pleated shade construction — the route holes are approximately 2–3mm in diameter and appear at every 4–6 inches across the width of the shade.
Why liners don’t fully solve them: The blackout liner has matching holes at the same positions as the face fabric route holes. If it did not — the cord could not pass through and the shade would not operate. The liner eliminates light through the fabric itself but not through the route hole positions.
What this looks like in a dark room: Faint pinpoints of light across the width of the lowered shade — typically very small and only visible from close range in a fully dark room. For most standard bedrooms — these pinpoints are not disruptive. For nurseries and home theaters — they may be noticeable.
The solution — NeatPleat / hidden back-ladder construction: NeatPleat and equivalent hidden back-ladder constructions (discussed in the pleat size guide) eliminate the back-ladder cord that creates route holes. When this construction is specified — route holes are eliminated entirely because there are no cords passing through the fabric.
Specify NeatPleat + blackout liner for the most complete blackout-lined pleated shade available. American Blinds offers this combination. SelectBlinds and Blindsgalore offer equivalent hidden back-ladder options — confirm availability at your specific fabric and liner combination before ordering.
Outside Mount Is Still Required for True Blackout
This is the single most important specification point that connects the liner upgrade to the complete blackout result — and no competitor guide makes this connection.
A blackout liner addresses one of four light sources in a window treatment:
| Light source | Addressed by blackout liner? | Solution |
|---|---|---|
| Through the fabric | ✅ Yes — 100% blocked | Blackout liner |
| Through route holes | ⚠️ Partially — small pinpoints remain | NeatPleat construction |
| Around the perimeter (frame gaps) | ❌ No | Outside mount |
| Above the headrail | ❌ No | Cassette headrail |
Without outside mount: Even a blackout-lined pleated shade with NeatPleat construction will have a visible stripe of light around all four sides of the window frame — between the shade edge and the wall surface.
With outside mount: The shade is mounted 2–3 inches above and beyond the frame on all sides, covering the frame perimeter completely. This eliminates the perimeter light gap.
The complete blackout specification for a pleated shade:
- Blackout liner ✅
- NeatPleat / hidden back-ladder construction ✅
- Outside mount (2–3 inches beyond frame on all sides) ✅
- Cordless (for safety and clean appearance) ✅
All four elements together produce true blackout performance from a pleated shade.
Bonded Liner vs Sewn Liner — The Durability Difference
Not all blackout liners are attached to the pleated face fabric in the same way — and the attachment method affects long-term light-blocking performance.
Heat-bonded liner: The blackout liner is bonded to the face fabric using heat and adhesive across the full surface area. The bond extends across the pleat fold lines — meaning the liner follows the fold of each pleat without separating.
Benefits: Better light blocking at the pleat fold lines because the liner is fully adhered with no gaps. More durable in long-term use.
Sewn liner: The blackout liner is attached by sewing at the edges of the shade — typically the top, bottom, and sides — rather than across the full surface. The liner hangs behind the face fabric but is not bonded to it at the pleat folds.
Benefits: The face fabric and liner can move slightly independently — which can make the shade feel lighter and allows the fabric to display its texture more naturally.
The long-term issue with sewn liners: Over time and repeated raising and lowering, the liner can separate slightly from the face fabric at the pleat fold lines, creating small gaps between liner and face fabric. At these gaps — light can enter even through nominally blackout material. After 3–5 years of regular use — a sewn liner may show reduced blackout performance at the fold lines that was not present when new.
When ordering: Ask the supplier whether the blackout liner is heat-bonded or sewn. For long-term blackout performance — specify heat-bonded liner where available. SelectBlinds and Graber both offer heat-bonded options on select pleated shade lines.
The Liner Upgrade Cost — What to Expect
No competitor article gives specific pricing. Here is what buyers should expect:
| Liner Type | Added Cost Per Window | Total Mid-Range (36×48 inch) |
|---|---|---|
| No liner (unlined) | — | $30–$50 |
| Privacy liner | +$5–$10 | $35–$60 |
| Room-darkening liner | +$10–$20 | $40–$70 |
| Blackout liner | +$15–$35 | $50–$75 |
| Blackout liner + NeatPleat | +$25–$50 | $55–$90 |
The value comparison: A blackout-lined pleated shade with NeatPleat and outside mount at $55–$90 per window mid-range delivers near-complete blackout performance — at significantly less than double-cell blackout cellular at $90–$150 per window.
Is the Liner Worth It? — The Verdict by Room
| Room | Is Liner Worth It? | Which Liner | Notes |
|---|---|---|---|
| Primary bedroom (standard sleeper) | ✅ Yes | Room-darkening | Avoid cordless + room-darkening conflict — confirm with supplier |
| Primary bedroom (light-sensitive sleeper) | ✅ Yes | Blackout + NeatPleat + outside mount | Complete system for maximum darkness |
| Nursery | ✅ Yes | Blackout + NeatPleat + outside mount | AAP supports dark sleep environment for infant duration |
| Guest bedroom | ⚠️ Optional | Privacy or room-darkening | Full blackout rarely needed for occasional use |
| Home office | ⚠️ Situational | Privacy liner | Only if screen glare from windows is the problem |
| Living room | ❌ Usually not | None | Daytime use rooms rarely benefit from blackout |
| Home theater | ✅ Yes | Blackout + outside mount | Projection contrast requires complete fabric blackout |
| Kitchen | ❌ No | None | Blackout in kitchen counterproductive — needs daylight |

Frequently Asked Questions
Can pleated shades be blackout? Yes — any pleated shade can be upgraded to blackout by specifying a blackout liner at ordering. The blackout liner eliminates 100 percent of light transmission through the fabric itself. However, light may still enter through route holes in the operating mechanism and through frame perimeter gaps. For complete darkness — specify blackout liner plus NeatPleat or hidden back-ladder construction plus outside mount together.
What is the difference between a privacy liner and a blackout liner on a pleated shade? A privacy liner blocks approximately 50 to 75 percent of light — it diffuses the light so objects inside appear as silhouettes from outside rather than clear shapes. A room-darkening liner blocks approximately 85 to 99 percent of light — the room becomes genuinely dark but a small amount of light may still be perceptible. A blackout liner blocks 100 percent of light through the fabric itself. According to Graber Blinds, a blackout liner eliminates outside light and prevents shadows or silhouettes from showing through entirely.
Why does light still come through my blackout pleated shade? Two likely causes: first, route holes — small openings where the operating cord passes through the fabric create pinpoints of light even with a blackout liner, as American Blinds specifically warns. Specify NeatPleat or hidden back-ladder construction to eliminate route holes. Second, perimeter gaps — light enters around the edges of the shade through the gap between the shade edge and the wall. Specify outside mount to cover these gaps.
Can I get cordless AND a blackout liner on a pleated shade? Yes — blackout liner and cordless are typically compatible. However, room-darkening liner (the middle option) is often NOT available with cordless lift per Blinds.com. If you want cordless plus maximum light blocking — specify blackout liner (not room-darkening) and confirm compatibility with the supplier before ordering.
How much does a blackout liner add to the cost of a pleated shade? A blackout liner typically adds $15 to $35 per window at mid-range pricing, bringing the total for a standard 36 by 48 inch cordless pleated shade with blackout liner to approximately $50 to $75. Adding NeatPleat or hidden back-ladder construction adds another $10 to $15. The complete blackout-specified pleated shade — blackout liner plus NeatPleat plus outside mount — costs approximately $55 to $90 per window, significantly less than blackout cellular shades at $90 to $150 per window.
Is a blackout-lined pleated shade as dark as a blackout cellular shade? Through the fabric — yes, both are 100 percent opaque. The remaining differences are: blackout cellular shades typically have fewer route holes (cells provide more structural support for the cord routing), blackout cellular provides R-4.80 insulation versus R-2.60 to R-3.00 for blackout-lined pleated, and blackout cellular provides sound dampening that blackout-lined pleated does not. For pure fabric blackout performance — the lined pleated shade matches cellular. For complete system blackout with insulation and sound — cellular is the better specification.
