Fire Retardant Curtains for Commercial Buildings: What Every Business Needs to Know

Introduction

Picture a busy hotel on a Friday evening. Guests are checking in, the restaurant is filling up, and housekeeping is turning rooms. Nobody is thinking about curtains. But if a fire starts, those curtains become one of the most important elements in the building. Will they resist the flame and buy precious evacuation time? Or will they ignite, sending fire racing from floor to ceiling in seconds?

That question is not hypothetical. Vertical hanging fabrics are among the highest-risk items in any commercial interior because fire climbs. A standard untreated curtain can become fully engulfed in under a minute. Fire retardant curtains are specifically engineered to interrupt that chain reaction, resisting ignition, suppressing flame spread, and self-extinguishing when the heat source is removed. In the UK, they are not optional for businesses. They are a legal requirement under the Regulatory Reform (Fire Safety) Order 2005.

Yet despite the clear legal and safety case, fire retardant curtains remain one of the most commonly overlooked elements in commercial fit-outs. Specifiers pick the right paint, the right flooring, the right lighting. Then curtains get added at the last minute, sometimes from a retail supplier with no fire certification at all. That gap in the specification is a compliance liability waiting to happen.

This article is designed to close that gap. It covers the UK regulatory framework, the technical standards behind fire retardant fabrics, how to choose the right specification for different building types, and the practical steps involved in procurement and maintenance. It also tackles one of the most common points of confusion in the industry: the difference between fire retardant curtains and fire curtains, two products that share a name but have almost nothing else in common.

Fire Retardant Curtains vs Fire Curtains: Why the Confusion Matters

Fire retardant curtains and fire curtains are fundamentally different products designed for fundamentally different purposes. Getting them confused can lead to dangerous specification errors, failed inspections, and wasted budgets. Let us set the record straight.

Fire retardant curtains are soft furnishing window treatments. They hang on tracks or poles at windows and interior openings. Their fabrics are engineered to resist catching fire and to self-extinguish if exposed to a flame source. They are tested and certified under BS 5867 Part 2, the British Standard for curtain and drapery flammability. They look and feel like normal curtains because, functionally, that is what they are. The fire protection is a property of the fabric, not the product’s physical role.

Fire curtains are something else entirely. They are active fire protection systems, typically consisting of a woven glass fibre or specialist composite material housed in a steel headbox. When a fire alarm or smoke detector triggers, fire curtains deploy automatically (usually by gravity failsafe) to form a physical barrier across an opening, preventing fire and smoke from spreading between building compartments. They are tested under BS 8524 (the UK standard for active fire curtain barriers) and EN 1634-1 (the European fire resistance test). Fire curtains are rated by integrity time, for example E60 (60 minutes of integrity) or EI60 (60 minutes of integrity plus insulation).

Both products are essential parts of a building’s overall fire safety strategy. But they are never interchangeable. If your fire risk assessment requires compliant window treatments, you need fire retardant curtains. If it requires compartmentation at an opening, you need a fire curtain system. This guide focuses entirely on the first category.

The Legal Landscape: Why UK Businesses Cannot Ignore Fire Retardant Curtains

In England and Wales, fire safety in non-domestic premises is governed by the Regulatory Reform (Fire Safety) Order 2005. This single piece of legislation replaced older fire certification regimes and placed direct responsibility on the “Responsible Person”, typically the building owner, employer, landlord, or facilities manager. The Order applies to virtually every workplace, commercial building, and shared area of residential buildings.

Under the Order, the Responsible Person must carry out a fire risk assessment that evaluates every element of the premises that could contribute to fire risk. Soft furnishings, including curtains and blinds, sit squarely within that scope. The Government’s own fire safety guidance and the DCLG fire risk assessment guides for specific sectors (residential care, hotels, offices, education) all reference BS 5867 Part 2 as the applicable standard for curtain fabrics.

What Happens If You Are Not Compliant?

The consequences of non-compliance are serious. They go well beyond a failed inspection.

• Enforcement notices and prohibition notices from the local fire and rescue service, which can force immediate closure of premises until issues are resolved.
• Criminal prosecution under the Fire Safety Order, which can result in unlimited fines for businesses and up to two years in prison for individuals found responsible.
• Insurance implications. If non-compliant curtains are found to have contributed to fire spread after an incident, insurers may reduce or refuse claims entirely. Many commercial insurance policies explicitly require fire safety compliance as a condition of cover.
• CQC action for care homes and healthcare providers. The Care Quality Commission inspects against Regulation 15 (Premises and Equipment), which requires that furnishings meet fire safety standards. A failed CQC inspection can result in warning notices, conditions of registration, or closure.
• Reputational damage. A fire incident linked to non-compliant furnishings makes headlines. For hospitality and care businesses that depend on public trust, the reputational cost can outlast any fine.

The bottom line: fire retardant curtains are not a design upgrade. They are a legal baseline. Every business that operates from non-domestic premises needs them, and the Responsible Person needs to be able to prove compliance with documentation.

BS 5867 Part 2: Understanding the Standard That Governs Your Curtains

BS 5867 Part 2 is the British Standard that defines flammability requirements for fabrics used as curtains, drapes, and window blinds in non-domestic environments. Published by the British Standards Institution (BSI) and last updated in 2008, it establishes three performance classifications: Type A, Type B, and Type C. Each type reflects a different level of fire resistance, measured through progressively more demanding test protocols.

Type A: The Baseline

Type A is the minimum standard of fire retardancy within BS 5867. All fabrics must achieve at least this level. However, Type A alone is generally insufficient for commercial environments. It is primarily relevant as a reference point rather than a practical specification target.

Type B: The Commercial Standard

Type B is the standard required for most commercial settings. To achieve Type B certification, a fabric sample is pre-washed through 12 laundry cycles and then subjected to a flame test. The fabric must not allow flame to spread to any edge, and no burning debris should fall from the material. Type B is the default specification for hotels, offices, restaurants, bars, retail spaces, schools, cinemas, and most public buildings.

Type C: The Healthcare Standard

Type C is the most demanding classification. The fabric undergoes 50 wash cycles at 75°C before testing. In addition to the no-spread and no-debris requirements, the after-flame and afterglow time must not exceed 2.5 seconds, meaning the fabric self-extinguishes almost immediately. Type C is required in hospitals (as recommended by the Department of Health’s HTM 05-03 guidance), care homes, secure mental health facilities, and other high-risk environments where occupants may be unable to evacuate quickly.

A critical compliance detail: BS 5867 applies to the complete curtain assembly, not just the face fabric. Both the face fabric and the lining must be independently certified. If a Type C face fabric is paired with a Type B lining, the curtain as a whole only achieves Type B. This is one of the most common specification mistakes in the contract curtain market. Always request fire test certificates for every component.

Inherently Fire Retardant vs Treated Fabrics: A Procurement Decision That Matters

When specifying fire retardant curtains, the most consequential decision is whether to use inherently fire retardant (IFR) fabrics or chemically treated fabrics. The choice affects compliance longevity, maintenance costs, aesthetics, and total cost of ownership over the life of the installation.

Inherently Fire Retardant (IFR) Fabrics

IFR fabrics are woven from fibres that are flame resistant at the molecular level. The protection is built into the chemical structure of the yarn itself. It cannot be washed out, worn away, or degraded by UV exposure. Whether the curtain is washed once or a hundred times, the fire retardant properties remain identical.

This permanence is what makes IFR the default choice for any environment requiring frequent laundering. Hospitals need thermal disinfection washes at 71°C or above. Care homes wash curtains regularly as part of infection control. Hotels cycle soft furnishings through industrial laundry systems as a matter of routine. In all these settings, IFR fabrics are the only practical way to maintain continuous BS 5867 compliance without tracking re-treatment schedules.

Leading UK contract fabric manufacturers such as Edmund Bell, Prestigious Textiles, iLiv, and Abbotsford Textiles produce extensive ranges of IFR fabrics certified to BS 5867 Type B and Type C. These include plains, velvets, linens, sheers, geometrics, florals, and wool-look textures in hundreds of colourways.

Treated (Chemically Applied) Fire Retardant Fabrics

Treated fabrics begin life as standard textiles (often cotton, linen, or polyester blends) and are then coated or dipped in flame retardant chemicals after weaving. The chemical layer creates a barrier that prevents easy ignition. However, this treatment is not permanent. Each wash, each exposure to moisture, each year of wear reduces the chemical layer’s effectiveness.

Most treated fabrics are certified for a limited number of washes, often around five, before they need professional re-treatment. This creates an ongoing compliance management burden. If re-treatment schedules are missed, the curtains may silently become non-compliant, leaving the building at risk and the Responsible Person exposed.

Treated fabrics do offer a lower upfront cost per metre. They also allow a wider range of base materials for designers who want natural fibre aesthetics. But when the total cost of ownership is calculated, including re-treatment fees, compliance tracking, and earlier replacement cycles, IFR fabrics are typically the more economical choice over a five to ten year horizon.

For most commercial procurement decisions, IFR is the safer and smarter investment. It removes the ongoing compliance headache and delivers consistent protection from day one to end of life.

Beyond Fire Safety: Performance Features That Add Value

Fire retardancy is the baseline. But modern contract curtain fabrics can deliver multiple performance benefits simultaneously, making them a harder-working investment for commercial buildings. Here are the key features to consider alongside FR compliance.

Blackout Properties

Blackout curtains use triple-pass coated linings to block 100% of incoming light. This is essential for hotel bedrooms, cinema rooms, lecture theatres, and student accommodation where sleep quality and screen visibility depend on complete darkness. Blackout linings can be specified in fire retardant versions that meet BS 5867, so there is no need to compromise between light control and safety.

Dimout Properties

Dimout fabrics reduce incoming light by 70% to 95% without total blockage. They are popular in conference rooms, offices, and healthcare day rooms where some ambient light is desirable but glare needs managing. Many dimout fabrics are inherently fire retardant, combining light management with permanent flame resistance.

Thermal Insulation

Thermal curtain linings add a dual-layer fabric that retains heat in winter and reflects solar gain in summer. For commercial buildings where energy costs are a significant operational expense, thermal curtains can contribute to more stable internal temperatures and lower HVAC demand. All thermal linings used in commercial settings should themselves meet BS 5867, ensuring the complete curtain assembly remains compliant.

Acoustic Benefits

Heavy curtain fabrics, particularly velvets and interlined constructions, absorb sound and reduce reverberation. In open-plan offices, co-working spaces, and meeting rooms, curtains can serve a dual role as acoustic treatment and fire-safe window dressing. This is an increasingly valued specification for modern workplace design.

Anti-microbial Finishes

In healthcare and care home environments, curtain fabrics with anti-microbial treatments help reduce pathogen transfer. These finishes can be combined with IFR properties for a single fabric that meets both fire safety and infection control requirements. Manufacturers like Edmund Bell offer ranges specifically designed for NHS and clinical environments.

Sector-by-Sector: What Different Commercial Environments Need

The right fire retardant curtain specification depends on the building type, the people who use it, and the level of risk involved. Here is a practical breakdown by sector.

Hotels and Serviced Accommodation

Hotels are classified as medium-risk premises because guests sleep in unfamiliar environments. BS 5867 Type B is the standard requirement across guest rooms, lobbies, restaurants, conference areas, and function suites. Blackout curtains are the norm in bedrooms. Dimout or voile options work well in public areas.

For multi-room hotel projects, consistency matters. Every room needs pattern-matched, professionally finished curtains in the same colourway. Specialist contract curtain suppliers with in-house workrooms can deliver that consistency across hundreds of rooms, complete with fire test certificates for every order.

Care Homes and Assisted Living

Care environments present unique challenges. Residents may have reduced mobility, cognitive impairment, or sensory conditions. Evacuation is slower and more complex than in a typical commercial building. The CQC requires compliance with Regulation 15, and the DCLG fire risk assessment guide for residential care explicitly references BS 5867.

Type C inherently fire retardant fabrics are the recommended specification for care homes. They withstand the frequent laundering that infection control demands. Fabric choices should also consider washability, stain resistance, and creating a warm, home-like atmosphere rather than an institutional feel.

Hospitals and Clinical Settings

NHS and private healthcare facilities require the highest specification. HTM 05-03 recommends Type C compliance. Curtains must tolerate thermal disinfection washes, anti-microbial treatments, and heavy duty use. IFR polyester is the standard. Fire test certification must be available for building control inspections and ongoing compliance audits.

Education (Schools, Colleges, Universities)

Classrooms and common areas are generally low to medium risk, requiring Type B. However, halls of residence and boarding houses where students sleep on-site may require Type C. Budget-friendly IFR plains in school or university brand colours are a practical and popular choice.

Offices and Corporate Interiors

Modern offices use curtains for aesthetics, acoustic zoning, glare reduction, and meeting room privacy. Type B is the standard. Wave heading curtains on silent-glide tracks have become the go-to for contemporary corporate fit-outs, offering clean lines and a minimal aesthetic that works with open-plan design. Space Commercial Interiors offers wave curtains in both 60mm and 80mm wave sizes across their full fire retardant fabric library.

Rental Properties and Holiday Lets

Any property where someone pays to stay falls under the Fire Safety Order. This includes Airbnb lets, holiday cottages, HMOs, and long-term rental properties. The London Fire Brigade’s guidance makes clear that fire safety law applies whether you rent one room or the whole house. Curtains must meet BS 5867 Type B. Landlords who supply non-compliant curtains are personally liable.

How to Procure Fire Retardant Curtains: A Step-by-Step Guide

Procurement is where good intentions meet practical reality. Follow these steps to ensure your fire retardant curtains are correctly specified, compliant on delivery, and properly documented.

1. Start with the fire risk assessment. Before specifying a single curtain, confirm the risk classification for each room. Your fire risk assessment should identify whether Type B or Type C is required and flag any rooms with enhanced risk (sleeping accommodation, restricted mobility, high occupancy).
2. Set the fabric brief. Determine whether you need blackout, dimout, thermal, voile, or standard curtains. Decide whether IFR or treated fabric is appropriate. For most commercial projects, IFR should be the default.
3. Choose a specialist contract supplier. Do not source from retail curtain shops. They rarely carry BS 5867 certified fabrics, and they cannot provide the fire test certificates you need. Work with a contract curtain manufacturer that supplies to the commercial and hospitality market.
4. Request fabric swatches. Evaluate the fabric in situ. Check colour under the room’s actual lighting. Confirm the handle and drape meet your aesthetic requirements. Verify that the swatch comes with BS 5867 certification details.
5. Confirm both face fabric AND lining are certified. This is the single most important compliance check. Request fire test certificates for every component of the curtain assembly before production begins.
6. Provide accurate measurements. Use your supplier’s measuring guide or arrange a professional site survey. Incorrect measurements waste time, money, and materials. For complex installations with curved tracks, bay windows, or high ceilings, a site visit is strongly recommended.
7. Specify heading style and track system. Match the heading to the room’s aesthetic and the track to the weight and fullness of the fabric. Pencil pleat, pinch pleat, eyelet, and wave are all available in FR fabrics.
8. Confirm delivery of fire test certificates. Certificates must arrive with the curtains, not as an afterthought. Store them with your fire risk assessment documentation. They are the proof that an inspector, insurer, or CQC assessor will ask for.
9. Consider professional installation. For projects with five or more windows, or for complex heading styles like wave, professional installation ensures a clean, consistent result and avoids damage to fabrics or tracks. Many contract suppliers offer nationwide fitting services.
10. Set up a maintenance schedule. Log the installation date, fabric type (IFR or treated), cleaning method, and wash frequency. For treated fabrics, set calendar reminders for re-treatment before the wash limit is reached.

Five Costly Mistakes Businesses Make with Fire Retardant Curtains

Avoid these common pitfalls that can leave your building non-compliant and your business exposed.

Mistake 1: Buying Retail Curtains for Commercial Premises

Retail curtains from high street stores or online marketplaces are designed for domestic use. They almost never carry BS 5867 certification and will not come with fire test certificates. Even products marketed as “flame resistant” may not meet the standard. Always source from a certified contract supplier.

Mistake 2: Certifying the Face Fabric but Forgetting the Lining

A curtain is only as compliant as its weakest component. If the face fabric is certified to Type C but the lining has no fire certification, the entire curtain fails compliance. Specify both components from the outset and demand certificates for each.

Mistake 3: Confusing Fire Retardant Curtains with Fire Curtains

As covered earlier, these are completely different product categories. Fire retardant curtains dress windows. Fire curtains are active compartmentation systems. If a specification document requests “fire curtains” for windows, clarify the intent before proceeding. The cost, installation, and purpose are worlds apart.

Mistake 4: Neglecting Re-treatment of Treated Fabrics

If you have opted for treated (non-IFR) fabrics, every wash degrades the chemical layer. Without a documented re-treatment schedule, your curtains can silently slip out of compliance. If tracking re-treatment feels burdensome, switch to IFR fabrics on the next replacement cycle.

Mistake 5: Failing to Store Fire Test Certificates

Having compliant curtains is only half the requirement. You must be able to prove compliance on demand. Fire test certificates should be stored centrally, linked to the specific rooms and windows they cover, and accessible for fire service inspections, insurance audits, and CQC visits. Without documentation, even compliant curtains cannot protect you from enforcement action.

The Case for Made-to-Measure Fire Retardant Curtains

Off-the-shelf fire retardant curtains exist, but for commercial projects they rarely deliver the fit, finish, or documentation that compliance demands. Made-to-measure curtains from a specialist contract supplier offer a level of quality and assurance that pre-made alternatives cannot match.

Every curtain is manufactured to your exact window dimensions, eliminating gaps, bunching, and uneven hems. Pattern matching is handled professionally, so in a multi-room hotel or care home, every window presents a consistent, polished appearance. You choose from the full range of heading styles, from classic pencil pleat to contemporary wave, rather than whatever happens to be in stock. And crucially, fire test certificates for both face fabric and lining are issued with every order.

Space Commercial Interiors manufactures all their fire retardant curtains in their own Yorkshire workroom. Their fabric library includes certified ranges from Edmund Bell, iLiv, Prestigious Textiles, and Abbotsford Textiles. They offer free fabric samples, clear measuring guides, and a UK-wide professional installation service for larger projects. For businesses that need compliance, quality, and style in a single package, a specialist made-to-measure approach is the most reliable path.

Quick Decision Table: Matching Your Building to the Right Specification

Frequently Asked Questions

1. Are fire retardant curtains and fire curtains the same thing?

No. Fire retardant curtains are fabric window treatments that resist ignition. Fire curtains are a completely separate product category: active fire protection systems made from woven glass fibre that deploy automatically to block fire and smoke between building compartments. They are tested under different standards (BS 8524 and EN 1634-1 for fire curtains vs BS 5867 for fire retardant curtains) and serve entirely different functions.

2. Does my business legally need fire retardant curtains?

If you operate from non-domestic premises in England or Wales, yes. The Regulatory Reform (Fire Safety) Order 2005 requires the Responsible Person to manage all fire risks, including soft furnishings. Curtains and blinds in commercial settings must be certified to BS 5867 Part 2.

3. What is the difference between BS 5867 Type B and Type C?

Both require the fabric to resist flame spread and produce no burning debris. The difference is in the pre-test washing. Type B fabric is washed 12 times before testing. Type C is washed 50 times at 75°C and must also self-extinguish within 2.5 seconds. Type C is for high-risk environments like hospitals and care homes.

4. Can I make my existing curtains fire retardant?

Potentially. Professional fire retardant spraying or dipping services can treat existing fabrics. However, this treatment is temporary and degrades with cleaning. For reliable long-term compliance, replacing non-compliant curtains with certified fire retardant alternatives is more practical and often more cost-effective.

5. How do I prove my curtains are compliant?

Through fire test certificates. Your curtain supplier should provide certificates for both the face fabric and the lining, referencing BS 5867 Part 2 and stating the Type (B or C). These certificates should be stored with your fire risk assessment and available for inspection.

6. Do fire retardant curtains look institutional or ugly?

Not at all. Modern FR fabrics are available in the same colours, patterns, and textures as standard furnishing textiles. Velvets, linens, sheers, geometrics, florals, checks, and plains are all available. The fire safety properties are invisible.

7. How long do fire retardant curtains last?

IFR curtains can last many years with proper care, as the fire retardant properties never degrade. Longevity depends on fabric quality, UV exposure, and cleaning frequency. Regular inspection is more important than a fixed replacement date. Include curtain condition in your annual fire risk assessment review.

8. What curtain heading styles can be fire retardant?

All of them. Pencil pleat, deep pleat, pinch pleat (double or triple), eyelet, goblet, cartridge, and wave headings are all available in fire retardant fabrics. The heading style is independent of the fabric’s fire performance.

Conclusion: Compliance, Safety, and Style in One Investment

Fire retardant curtains sit at the intersection of legal obligation, life safety, and interior design. Getting them right protects the people inside your building, satisfies the regulators and insurers who oversee it, and contributes to an interior that looks as good as it performs.

The most important takeaways? First, understand that fire retardant curtains and fire curtains are entirely separate products. Do not confuse them. Second, know your standard: BS 5867 Type B for standard commercial use, Type C for healthcare and high-risk settings. Third, choose inherently fire retardant fabrics wherever possible, because permanent protection eliminates ongoing compliance risk. Fourth, always certify the full curtain assembly, face fabric and lining together. Fifth, keep your documentation ready for inspection at all times.

Working with a specialist contract supplier makes all of this simpler. Space Commercial Interiors brings together a comprehensive library of BS 5867 certified fabrics, a dedicated Yorkshire workroom for made-to-measure production, fire test certificates issued with every order, and a professional installation service that covers the whole of the UK.
