Technical Curtains Specification: B2B Model in 8 Sections

A written specification document is not an administrative formality. It is the tool that allows comparing multiple quotes on equivalent bases, legally binding the supplier, defining liability in case of defect, and tracking the regulatory compliance of the equipment for 10 to 15 years. The absence of a written document is the most common purchasing error for a significant fleet.

To verify a delivery report, see the article how to know if a curtain is fire-retardant. For selecting a manufacturer to consult, read the 7 selection criteria. For budget framing, consult the 2026 B2B price guide.

Why a written specification document for a B2B curtain project?

Four reasons make this exercise essential beyond a few curtains.

1. Comparability of quotes. Without a common specification document, two quotes cannot be compared. One might include M1, the other might not. One might provide for 100 industrial washes, the other 30. The specification document puts suppliers on a strictly identical technical basis.
2. Legal commitment. A specification document attached to the purchase order becomes a contractual document. Any deviation between delivery and the specification document is an enforceable non-conformity, entitling to formal notice, replacement, or price reduction.
3. Regulatory traceability. In case of a safety commission visit or an incident, the operator must prove that they required an M classification in compliance. The archived specification document is the element that documents the purchasing diligence.
4. Operational sustainability. Over 10 to 15 years, the purchasing team changes, the General Services Director changes, the safety commission changes. The specification document is the document that transmits the technical memory of the fleet and allows for identical replacement.

The 8 sections of a complete specification document

Section 1: Project identification

The opening section defines the client's identity and the nature of the project. Minimum six lines.

Section 2: Technical specifications per area

This section describes, area by area, what is expected. For each area, six pieces of information are essential.

1. Area designation (room 101, multi-purpose hall, lobby, staircase B).
2. Glazed surface to be equipped and number of windows or bays.
3. Exact dimensions per window (bay width, bay height, ceiling height, wall return width).
4. Minimum M classification required (M1 or M2) according to articles AM 11 to AM 13 of the decree of June 25, 1980.
5. Imposed or anticipated fixing type (eyelets, pleating tape, fasteners, rings, rods).
6. Specific constraints (presence of sensors, access to the opening mechanism, intervention constraint without interrupting activity).

A summary table facilitates the supplier's reading. The more precise the description, the firmer and fairer the quote will be.

Section 3: Required performance

Four families of performance can be specified for a B2B curtain. Each must be quantified to be enforceable.

An enforceable formulation always mentions the reference standard and the quantified target value. A marketing formulation ("high performance," "maximum insulation," "ultra-blackout") creates no enforceable legal commitment against the supplier.

Section 4: Mandatory documents upon delivery

The specification document explicitly lists the documents to be provided upon delivery. Minimum five documents.

• Nominated M classification report issued by a recognized laboratory (CSTB, LNE, IFTH), dated.
• Fabric technical sheet (fiber composition, weight, fire-retardant method, additional certifications such as Oeko-Tex).
• Delivery note with exact dimensions per curtain delivered and internal reference number.
• Invoice mentioning compliance with the specification document.
• Written warranty conditions (duration, scope, exclusions, invocation procedures).

Optionally: test report on finished product (for multi-layered items), commissioning slip, recommended maintenance sheet. The exhaustive list is in the specification document, which prevents any discussion about the scope of delivery.

Section 5: Deadlines and schedule

Five milestones must be documented with written commitment.

• Quote deadline: 24 to 48 hours for a standard request, 5 working days for a complex configuration.
• Production time after order: 4 to 8 weeks depending on complexity (custom dyeing, M1 certification for rare fabric).
• Delivery time after production: 5 to 15 days depending on distance and coordination.
• Possible installation time: 1 to 5 days depending on volume and access.
• Acceptance time upon delivery: 5 to 10 working days for documentary and physical verification.

Any critical date (safety commission visit, back-to-school, seasonal opening) must be explicitly mentioned with a safety margin of 2 to 4 weeks.

Section 6: Warranties and after-sales service

The specification document specifies a minimum of three warranties, with their duration and scope.

Three after-sales service commitments complement the warranty commitment.

• Ability to replace identically during the minimum warranty period.
• Re-issuance of a recent test report upon request (safety commission, insurer).
• Intervention time for reported defect: 5 to 10 working days for analysis, replacement, or reduction depending on severity.

Section 7: Commercial terms

Six commercial clauses must be included in the B2B specification document.

1. Price excluding tax per item (curtains, accessories, services) with totals per area and grand total.
2. Volume discounts applied according to documented tiers (e.g., 5% from 50 curtains, 15% from 200).
3. Payment terms: down payment upon order, balance upon delivery or payment schedule in case of progressive deployment.
4. Payment deadline: in accordance with the law (legal deadline, or conventional deadline specified on the purchase order).
5. Penalties for production or delivery delays (quantified formula, e.g., 1% of the ex-tax amount per week of delay capped at 10%).
6. Quote validity conditions: minimum 30 days, firm and definitive for the described scope.

Section 8: Acceptance upon delivery

The acceptance procedure structures the verification at the time of delivery. Five mandatory control points.

1. Documentary control: presence and conformity of all documents listed in section 4.
2. Visual control: conformity of colors to the validated sample, quality of manufacturing (sewing, hem, fastenings).
3. Dimensional control: measurement of each curtain on critical dimensions (width, height, hem height) with specified maximum tolerance (typically +/- 5 mm).
4. Inventory control: number of curtains delivered, number of accessories, presence of optional ordered parts.
5. Acceptance report signed by both parties, with mention of any reservations and the deadline for their resolution.

An acceptance validated without reservation triggers commissioning and registration of the report in the safety register. An acceptance with reservations triggers formal notice to the supplier within the contractual deadline.

Frequent errors in a curtain specification document

How Kurtens works with a specification document

Kurtens provides B2B quotes within 24 hours based on a complete specification document, with explicit mention of compliance or proposed deviations from the specification document. The fabric technical sheet and M classification report are transmitted during the study phase. A color and material sample is provided upon request before validation. M1 certification is available upon request, with the extra cost included in the quote without a separate line.

Commitments regarding deadlines, warranty, discounts, and commercial terms are written on the quote and transferred to the purchase order. No minimum order is imposed. Payment by administrative mandate is accepted for local authorities within the standard deadlines for public procurement.

To submit a specification document, see the custom professional curtains page or custom fire-retardant curtains page.

Frequently asked questions about technical curtain specifications

Note: this article proposes a structuring model for a B2B technical curtain specification document. It does not replace consultation with a legal professional or a professional buyer for sensitive projects, nor reading the public procurement code for public contracts. The proposed formulations are indicative and must be adapted on a case-by-case basis.

To submit a specification document and obtain a B2B quote: request a B2B quote. Response within 24 hours, M1 certification on request, CSTB or IFTH test report attached upon delivery.
