1. Introduction

HAG Ltd. has provided bespoke fire curtains and smoke curtains manufactured to suit specific site requirements to companies in the UK and worldwide since 1983.

This complete guide to fire curtains and smoke curtains has been compiled to help you find the right curtain for your premises.


2. Legal requirements for employers and building owners

Legal compliance

You’re responsible for fire safety in business or other non-domestic premises if you’re:

You’re known as the ‘responsible person’. As the responsible person you must carry out and regularly review a fire risk assessment of the premises. This will identify what you need to do to prevent fire and keep people safe. (source:

All fire curtains in England and Wales must be compliant to the Regulatory Reform (Fire Safety) Order 2005 (in Scotland the equivalent are: Fire (Scotland) Act 2005, Fire Safety (Scotland) Regulations 2006 and in Northern Ireland the equivalent are: The Fire and Rescue Services (Northern Ireland) Order 2006, The Fire Safety Regulations (Northern Ireland) 2010 ).  This states that fire doors require mandatory servicing for optimum safety in the event of an accident.

With regular maintenance, your premises will be compliant to legal obligations like the current Health and Safety Act 1974 Regulation 18, which stipulates that all equipment should be:

All doors must comply with British Standards and CE certified (in future to be replaced by UKCA certifications in England, Scotland and Wales). Failure to do so can result in prosecution or can invalidate your insurance and warranty. You must be able to provide all relevant documents and plans in the event of a Health and Safety inspection.


3. Starting with the building fire strategy

Fire protection is paramount in designing today’s workspaces and industrial premises. It’s one of the few things that takes precedence even over security.

There are many factors to consider when specifying a fire curtain or smoke curtain for property and personnel protection. The building fire strategy report should be the first and most important element to review, as this will detail how the entire emergency procedures and safety devices will work together in the event of fire and evacuation.

Once you have reviewed this document you should consider the following when specifying fire curtains:


4. Standards

The primary standard for specifiers, architects, fire engineers specifying active fire curtain barrier assemblies include:
BS EN 1634 Fire resistance and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware – Fire resistance test for door and shutter assemblies and openable windows
BS EN 16034:2104 Pedestrian doorsets, industrial, commercial, garage doors and openable windows. Product standard, performance characteristics. Fire resisting and/or smoke control characteristics

BS8524-1 Active fire curtain assembly – Specification

BS 8524-2 Active fire curtain barrier assemblies – code of practice for applications, installation & maintenance

BS EN 13501 Fire classification of construction products and building elements – Classification using data from fire resistance tests, excluding ventilation services
BSI PAS 121 Specification for active fire curtain barrier assemblies and active fire barrier assemblies with smoke rating
BS EN 12101 Smoke and heat control system


Fire Curtains & the two product standards BS 8524 & BS EN 16034

There are two product standards for Fire Curtains; both are acceptable and legal for UK & European laws.

BS EN 16034: 2014

The latest European Standard for fire curtains, was introduced by Brussels in 2014 to covering pedestrian doorsets, industrial, commercial, garage doors and openable windows & Fire curtains.

The test covers design, construction & performance, carried out by a third-party certified laboratory fire test with self-closing requirements.

BS 8524

This is split into two main sections.

BS 8524 -1

This is the test standard of the fire curtain performed at a third-party certified laboratory. This standard covers the design, construction & performance of the fire curtain, The test includes operation cycles, impact & motor load testing.

BS 8524-2

Is the standard for the installation & Service of the fire curtains, with-in this standard there is a requirement for the installer to be audited by a qualified third part accredited organisation. Unfortunately, there are currently no UK third part accredited organisations providing this, therefore there is no alternative but to be assessed by the manufacturer of the product.


Why are there two standards?

BS 8524 was created by an individual company many years ago before BS EN 16034 was introduced and ratified by the EU in 16034.

BS 8524 Only applies to fire curtains rather than BS EN 16034 with applies to multiple fire protection products and gives consistency across European standards.


Which standard should I choose?

BS 8524 fire curtains come with a premium cost, when directly compared to those tested to BS EN 16034. As both options are legal & certified, it is therefore subjective if it is worth the additional cost. Each manufacture and installer will always profess to their personal commercial interest. HAG Ltd. offer a range of products compliant to both standards, so the customer, architect and fire officers can decide.

Your fire officer & building control officers will ultimately make the decision between the two standards. We would reiterate, that both standards are compliant and legal, and both are certified as life saving devices.


5. Fire Curtains and smoke curtains explained

Fire curtains and smoke curtains are designed to be used in doorways, lift doors, in corridors and egress areas where it is important for:

They are typically made from a woven fibreglass material that is stored in a headbox at a high level and activated by an emergency alarm device to descend to its ‘safe position’ – normally the floor – thus creating a barrier to smoke and/or fire.

What is the difference between a fire curtain, a smoke curtain and a fire & smoke curtains?

All three products products must be deployed in an appropriate manner to meet the building’s fire safety strategy.

Fire resistance level

All fire curtains and smoke curtains are performance tested and the results are provided in three categories:

The performance in these three categories can be stated individually or in combination to provide a fire resistance level (FRL) for a curtain.

Fire resistance level is rated on a scale of 60 to 240 minutes.

Product compliance

Fire curtains are tested to BS EN 16034-1 and manufactured in conjunction with EN 13241-1 & EN 13501-2 and are classified as a machine, requiring the CE identification.

Government legislation changed 1st November 2019. All new fire curtains and smoke curtains must be fire tested and compliant to latest standard BS EN 16034:2014 & CE Marked to BS EN 13241-1:2003. Products tested to 2008 standard are prohibited by law.

All of HAG’s fire curtains have been independently tested and CERTIFIRE certified by the international fire testing experts at Warringtonfire. Test reports are available on application.

Fire system integration

Fire curtains are normally wired into their independent, programmable interface panels, to automatically operate when the mains alarm / alarm device is activated. A fiberglass curtain is guaranteed closure wih the implementation of a gravity failsafe control panel, referred to as a GFS.

Fire curtains are held in the open position on a day-to-day basis, closing in the event of a fire with a pre-programmed closing protocol which could be delayed drop, split drop or immediate full closure.

The surrounding structure must match the specified fire/smoke product to maintain integrity. All fire and smoke products require regular testing and maintenance under UK law.

Fire curtain features (optional or specified)

AV (audio visual) panels can be attached to any fire/smoke curtain system and are wired into the GFS panel. On activation of the mains alarm/ alarm device, the AV panel activates a flashing beacon and
audio alarm signalling the imminent closure of the safety curtain.

Mounting of fire curtains

Fire curtains can replace the more traditional fire doors in some cases, leading to more open corridors and doorways. A fire curtain fits into a slim box casing that sits out of the way above your doors or hatches, dropping automatically only when it is needed. The casing can be specified to a suitable RAL colour to blend in with your interior colour scheme. This inconspicuous design makes it perfect for areas where space is important.

Hospitals are a good example of a premises that can benefit from this type of fire protection where heavy fire doors or shutters with their frames and guide rails would reduce the width of the corridor hindering the movement of staff, patients as well as beds and wheelchairs.

Physical Security

Neither fire curtains nor smoke curtains provide any level of physical security; fire shutters should be used if this is required (see this guide to fire shutters).


6. Components

There are many components that make up the design of a fire or smoke curtain which work together in the event of an emergency to keep the building occupants safe from harm, and property safe from damage.

The curtain is manufactured from a woven fibreglass and stainless-steel fabric with a coating of intumescent silicone. Metal studs are sewn down the side of the curtain to ensure its correct position in the guide frames whilst in operation.

Smoke seals
A smoke seal provides an all-round physical barrier to prevent smoke passing through the construction of a fire curtain. This is achieved by the curtain tabs passing through the smoke seals as the curtain deploys. Figure 1 identifies the three major components, 1. a standard side guide. 2. smoke seals and 3. the smoke seal mounts.


Guides rails
Two galvanised steel side guide rails of 100 mm x 50 mm.

Head plates
Two galvanised steel head plates hold the shaft with the curtain, sizing dependent upon the height of the application.

Head Box
The fire curtain assembly comprises of a box housing at high level in which sits the shaft, tubular motor and wrapped curtain. The box is attached to channel section guides at each end.

Bottom Rail
A galvanised steel angle either side of the curtain, bolted together, forms a ‘T’ shaped bottom section to aid in the gravity drop of the curtain and provide a flat seal across the bottom/floor.

Head box, guides and bottom rail are galvanised at source and can be powder coated as required to any standard RAL or BS4800 colour. Fire curtains are naturally silver grey or charcoal finish, dependent on specification.

Curtains are supplied with gravity failsafe control panel with in-built lead-acid battery support.

Control Options
Dependant on the site fire protection requirements, various options are available to ensure compliance:

All systems come with a GFS control panel. This takes the alarm signal from the mains alarm system, or localised detectors, and performs its closing protocols. In the event of a power outage, the system is designed to self-close when the internal battery pack drops below safe operating voltage – thus ensuring continuity of safety.

The control panel comes with numerous other features including timer delay, 2-stage closure, and is fully programmable pre- or post-installation.


8. Maintenance & Safety Checks

Like with any mechanical doors, it is important to make sure your doors are regularly serviced. According to Regulation 5 of the Workplace (Health Safety and Welfare) Regulations 1992, all powered doors must be “checked at regular intervals, as appropriate, by inspection, testing, adjustment, lubrication, repair and cleaning.”

If you are the owner of a property, you must comply with certain laws to prevent the spread of flames and smoke. According to the Regulatory Reform (Fire Safety) Order 2005, all emergency doors must be regularly serviced. It states that:  “…the responsible person must ensure that the premises and any facilities, equipment and devices provided are subject to a suitable system of maintenance and are maintained in an efficient state and in efficient working order and in good repair”.

Fire curtains must be serviced every six (6) months to ensure they are in working condition. Risk assessments must be performed to identify and remove all fire risks, which includes checks to the door.

According to the Local Government Association, failure to provide adequate fire safety measures can be punished by a fine “currently of up to £5,000 in the Magistrates’ Court, or by an unlimited fine and/or two years imprisonment in the Crown Court.”


9. Door regulations

Door signage regulations

One of the first steps is making sure the correct signage is visible above any fire door in a non-domestic building. It should have signage on both sides. The sign should indicate clearly that it is a fire door. Watch for further details such as “Keep Locked” to keep the premises safe.

Escape routes including corridors and staircases should be properly protected. In any domestic dwelling which has two or more levels, any door which leads to the staircase must be indicated as a fire door.

Whilst the required fire resistance period cannot be lowered, it is important to understand that the minimum is usually 60 minutes. In any other situation 30-minute fire doors are allowed.


10. Frequently asked questions

Whilst both are fabric-based products deployed by a fire control system they have different design and characteristics. A fire curtain is designed to prevent the spread of fire whilst a smoke curtain is designed to spread of smoke. Neither provide physical security.

Due to varying size and specifications all fire curtains and smoke curtains are bespoke manufactured to individual requirements resulting in significant variance from one model cost to another.
