Cost of a Custom Professional Curtain: 2026 Price Guide
The price of a custom professional curtain in B2B ranges from €80 to €600 per panel depending on four parameters: the fabric composition (inherently fire-retardant or chemically treated), the total area ordered, the required M1 or M2 classification, and the combined additional features (blackout, sound attenuation, thermal insulation). For a complete installation, progressive discounts apply from 50 curtains, allowing prices to drop to €60-€200 per panel for orders of several hundred units. B2B quotes are issued within 24 hours based on specifications.
Compared to purchasing a curtain for a home, the B2B price is calculated according to different rules: volume, regulatory requirements, combined performance, document traceability, and a usage horizon of 10 to 15 years. This article details price ranges by sector, the variables that affect the price, hidden costs to anticipate, and the calculation of the total cost over 10 years.

Why a B2B price is calculated differently from a B2C price
Five specificities distinguish a B2B quote from a retail sale.
- Volume effect. A stock of 100 curtains does not sell for 100 times the price of a single curtain. Volume discounts can reach 30 to 40% compared to the public unit price, particularly for high-volume fabrics and catalog colors.
- Regulatory requirements. Curtains intended for public access buildings must be classified M1 or M2 depending on the space, accompanied by a dated nominative report. The additional cost related to certification is included in the quote and typically represents 5 to 20% depending on the fabric.
- Combined performance. A B2B curtain often integrates several simultaneous performances (M1 + 100% blackout + sound attenuation + thermal insulation), with a report issued on the assembled product. Each added performance represents an additional material and manufacturing cost.
- Document traceability. The quote includes the provision of the classification report, technical data sheet, and commissioning slip. These documents are free from a structured manufacturer, but are paid for or unavailable from an opportunistic reseller.
- Commercial terms. B2B quotes distinguish ex-tax prices (recoverable VAT for most businesses), payment terms (30 to 60 days), delivery terms (Incoterms), and late payment penalties. These clauses are not found in a retail sale.
The six variables that determine the price of a B2B curtain
| Variable | Impact on price | Indicative range |
|---|---|---|
| Fabric composition | Inherently fire-retardant costs more to purchase than chemical treatment | +30 to +60% for inherent |
| Total area per panel | Heights greater than 270 cm and widths greater than 300 cm increase the price per m² | +15 to +30% beyond standard dimensions |
| Required M classification | M1 adds a material and certification surcharge compared to an unclassified fabric | +5 to +20% depending on fabric |
| 100% blackout (class 4) | Dedicated layer (coating, metallization or multi-layer) added to the construction | +25 to +50% |
| Measured acoustic performance | High-density acoustic lining with measured report | +30 to +60% |
| Custom color | Dyeing on order, not in weaver's catalog | +20 to +40% and minimum meters required |
These ranges are indicative. For a real project, the price is built in layers: base fabric, addition of classification, addition of each performance, addition of manufacturing (eyelets, tape, hem, lining), addition of accessories (rods, tiebacks), addition of services (transport, on-site measurement, delivery coordination).
Price ranges by B2B segment
The figures below are indicative ranges to be confirmed by quote depending on the project configuration. All values are in euros ex-tax.
| B2B Segment | Typical configuration | Price per panel | Full stock budget |
|---|---|---|---|
| Standard hotel room | M2 + 100% blackout curtain, 2 panels per room | €120 to €260 ex-tax | €15,000 to €50,000 ex-tax (50 rooms) |
| Premium hotel suite | M1 + blackout + measured acoustic curtain, height over 270 cm | €280 to €600 ex-tax | €5,000 to €12,000 ex-tax (4 windows) |
| Nursing home resident room | M2 + blackout curtain, reinforced hem, soothing color | €110 to €220 ex-tax | €10,000 to €25,000 ex-tax (50 rooms) |
| School ERP (primary school) | M2 + blackout curtain, standard dimensions of the establishment | €80 to €180 ex-tax | €4,000 to €10,000 ex-tax (10 to 20 windows) |
| Municipal multi-purpose hall | M1 curtain on stage, M2 in circulation areas, height 4 to 6 m | €250 to €550 ex-tax | €8,000 to €28,000 ex-tax |
| Open plan office | M2 + measured sound attenuation curtain, corporate color | €140 to €280 ex-tax | €12,000 to €30,000 ex-tax (20 to 40 bays) |
| Restaurant or reception hall | M2 + daytime blackout curtain, decorative color | €180 to €380 ex-tax | €6,000 to €18,000 ex-tax |
These ranges include fabric, manufacturing, and standard installation accessories. They do not include installation, transport, or ancillary services (on-site measurement, removal of existing items). For a firm quote, a nominative quote based on specifications is essential.
The volume effect: documented progressive discounts
Three tiers of progressive discounts apply in B2B depending on the quantity ordered and the type of fabric selected.
| Ordered volume | Typical progressive discount on unit price | Use case |
|---|---|---|
| 1 to 20 curtains | Reference price (no progressive discount) | Small project, suite, single room |
| 21 to 50 curtains | 5 to 10% discount | Small hotel, primary school, media library |
| 51 to 200 curtains | 10 to 20% discount | Medium hotel, complete nursing home, multi-purpose hall |
| 201 to 500 curtains | 20 to 30% discount | Large hotel, hostel, extended office park |
| More than 500 curtains | 30 to 40% discount (negotiated on a case-by-case basis) | Multi-site hotel chain, large tertiary park |
Phased deployment over several years can benefit from an intermediate progressive discount if the total commitment is contractually validated from the first tranche. This approach is common in local authorities with a Multi-Year Investment Plan (PPI) that spreads expenditure over 3 to 5 years while securing the price.
Hidden costs to anticipate in a B2B budget
The price of the curtain represents only 60 to 80% of the total project budget. Five additional items complete the budget.
- Installation. Carried out internally by technical services or subcontracted to a partner installer. Allow €30 to €80 ex-tax per curtain for external installation depending on the complexity of access and the type of fastening.
- Curtain rods, brackets and accessories. For a heavy curtain (multi-layer M1 blackout), a minimum diameter of 28 mm is necessary. Allow €40 to €150 ex-tax per window depending on length and finish.
- Dismantling of existing items and disposal. For a renovation, removal and sorting of old stock represents €10 to €30 ex-tax per curtain.
- Transport and delivery coordination. Depending on the volume, transport is included or billed separately. Allow €200 to €800 ex-tax for standard national delivery.
- On-site measurement. For a complex project, a preliminary technical visit can be billed €200 to €600 ex-tax. For a committed B2B project, this service is often offered or deducted from the order.
In total, these additional items typically represent 15 to 30% of the total budget depending on the configuration.
Forecast budget over 10 years (industrial TCO)
The total cost of ownership (TCO) of a curtain inventory is not limited to the purchase price. It includes industrial washing, any re-treatments, partial replacements, and complete renewal at 10 or 15 years. The calculation changes radically depending on the fabric chosen.
| Item over 10 years | Inherently fire-retardant fabric | Chemically treated fire-retardant fabric |
|---|---|---|
| Initial purchase (100 curtains, 8 m² stock) | €30,000 to €50,000 ex-tax | €20,000 to €35,000 ex-tax |
| Industrial washes (2 per year, 10 years) | €4,000 to €8,000 ex-tax | €4,000 to €8,000 ex-tax |
| Fire-retardant re-treatment (beyond 50 washes) | €0 | €10,000 to €20,000 ex-tax (workshop re-saturation) |
| Partial replacement (5% breakage per year) | €1,500 to €2,500 ex-tax per year | €1,000 to €1,700 ex-tax per year |
| Complete renewal at 10-15 years | Not before 12-15 years | Probable at 8-10 years |
| Estimated 10-year TCO | €50,000 to €80,000 ex-tax | €50,000 to €90,000 ex-tax |
An inherently fire-retardant fabric, more expensive to purchase, is almost always cheaper over 10 years as long as regular washing is planned. This equivalence or economic advantage disappears if the stock is not washed (in which case a treated fabric remains competitive).
Kurtens B2B quoting process
Kurtens issues B2B quotes within 24 hours based on specifications describing: curtain area, required performance (M1, blackout, acoustic, thermal), color, type of fastening, and delivery schedule. A color and material sample is provided upon request before validation. M1 certification is available upon request, the additional cost is included in the quote without a separate line item. No minimum order is imposed.
Payment by administrative mandate is accepted for local authorities, within standard public procurement deadlines. Delivery conditions are specified in the quote. Installation is not carried out directly by Kurtens, who can refer to partner installers in the region.

Frequently asked questions about the price of a custom professional curtain
Why does the same curtain cost more in B2B than in B2C?
A B2B curtain almost always includes elements that a B2C curtain does not require: M1 or M2 classification with nominative report, combined performance (blackout, acoustic, thermal), document traceability, multi-year warranty, reinforced fastenings for heavy curtains. At equal volume, the price difference can be 30 to 80%. At B2B volume (50, 100, 500 curtains), progressive discounts often bring the unit price below the standard B2C rate.
Is the M1 price always higher than an unclassified curtain?
Yes, but the additional cost is more moderate than one might think. An inherently fire-retardant fabric typically costs 30 to 60% more to purchase than an equivalent unclassified decorative fabric. A chemically treated fire-retardant fabric costs 10 to 25% more. Over 10 years, the inherent fabric becomes economically advantageous as soon as regular washing is planned, as explained in the TCO table in this article.
What is the price difference between inherent and chemically treated fabric?
At purchase, an inherently fire-retardant fabric costs 30 to 60% more than a cotton or linen fabric with added chemical treatment. Over the entire lifespan of the curtain, the differential reverses: the inherent fabric retains its M1 classification throughout its useful life (10 to 15 years), while the treated fabric loses its classification after approximately 50 industrial washes and requires either re-treatment (€10 to €30 ex-tax per m² treated) or complete replacement.
Does the B2B quote include curtain installation?
Not systematically. Most manufacturers deliver the finished curtains and refer to a partner installer for installation, which is billed separately. Allow €30 to €80 ex-tax per curtain for external installation, more for complex sites (high ceilings, difficult access, presence of active public access buildings). Request a separate installation quote in parallel with the manufacturing quote for a complete budget overview.
What are the volume thresholds for progressive discounts?
The usual tiers are 20, 50, 200, and 500 curtains. Moving from one tier to another lowers the unit price by 5 to 10 points at each threshold. Beyond 500 curtains, negotiation is on a case-by-case basis depending on the project complexity, the type of fabric selected, and the delivery schedule. Phased deployment over 3 to 5 years can benefit from maximum progressive discounts if the total commitment is contractually validated from the first tranche.
How much should be budgeted to equip a 50-room hotel?
For 50 standard rooms with an M2 blackout curtain in 2 panels per room, i.e., 100 panels in total, the budget is between €15,000 and €50,000 ex-tax depending on the fabric chosen, color, and options. To this price are added rods and accessories (€3,000 to €7,500 ex-tax), external installation if applicable (€3,000 to €8,000 ex-tax), and transport (€200 to €800 ex-tax). This results in an overall budget of €21,000 to €65,000 ex-tax for a 50-room standard hotel.
Note: the price ranges presented in this article are indicative, based on observation of the B2B market for technical curtains in France in the first half of 2026. They do not constitute a quote and may vary depending on the weaver, the complexity of the specifications, the delivery schedule, and market conditions. For a firm quote, a detailed nominative quote based on specifications is necessary.
To obtain a B2B quote for your project: request a B2B quote. Response within 24 hours, volume discounts, M1 certification upon request, CSTB or IFTH report attached to delivery, administrative mandate accepted for local authorities.
