Frequently Asked Questions

Got some

Why is choosing a third-party accredited company vital for your Business ?

Fire safety is all about protecting life and property. It is a legal requirement for the purchaser of fire safety services to ensure that the person or organisation carrying out the work is ‘competent’.

Third-Party Certification is evidence that a service or product adheres to certain standards. An independent expert, the third party, has assessed the service or product and certified that it complies with those standards.

What data/documentation should I ask for to demonstrate that products is suitable for use?

Manufacturer’s marketing information may not always include information for a particular field of application. The suitability of use is best justified by the manufacturer, by:-

The production of a valid fire test or assessment report against the requirements of BS 476: Part 20, or a European fire classification report to EN 13501-2 (when tested to EN 1366 Parts 3 or 4 as appropriate) as issued by a UKAS accredited fire test laboratory or in the case of an assessment by a competent person or body, which should adequately demonstrate the suitability of a fire stopping product for use within a specific application or a range of applications.

Refurbishment of an existing building. The exiting services are both installed and live the requires fire resistance of the wall is increased. How should I proceed and deal with inaccessible areas?

The law requires that a relevant fire risk assessment is made and maintained to identify all potential hazards and associated risks throughout the life and use of the building and that all actions taken are recorded. The fire resistance and or other provisions should be enhanced in accordance with regulatory requirements to reduce risks to an acceptable level. The methods used can only be determined in relation to a particular problem.

Why do I need to Paint steelwork with fire protection coating?

In extreme heat, any steel under load will buckle and warp, for example, in a fire situation, the stability of steel-framed buildings may be affected. Intumescent paints protect the steel from the heat, by forming an insulating layer between the metal and the heat source. The paint also gives off a small amount of moisture, further cooling the steel.

Why do I need to Paint concrete with fire protection coating?

In extreme heat, the concrete under load could buckle and warp, for example, in a fire situation, the stability of the buildings may be affected. Intumescent paints protect the concrete if not thick enough from the heat, by forming an insulating layer between the concrete and the heat source. The paint also gives off a small amount of moisture, further cooling the substrate.

What do fire protection coatings do?

Fire protection coatings stop the material from burning through and offer a higher level of protection than flame retardants. Usually fire protection is rated as 30 or 60 minutes (BS476 Part 22 (1987)) and European testing.

Should I provide fire stopping around combustible pipes which are less than 40mm in diameter?

Yes, Approved Document B states: “If a fire-separating element is to be effective, every joint or imperfection of fit, or opening to allow services to pass through the element, should be adequately protected by sealing or fire-stopping so that the fire resistance of the element is not impaired”.

Can I Mix and match components from different manufactures, or different systems made by there same manufacture, when installing fire stopping?

The simple answer is no. While it may be tempting to use e.g. manufacturer A’s mineral fibre batt with manufacturer B’s adhesive, the combination is unlikely to have been tested and therefore may not perform in the fire as intended.

All materials must have full application details and tests before the application.

Do I need door seals?

Heat and smoke seals are required for your fire door. They completely shut off all gaps in the fire door frame, serving as an excellent defence against fire and smoke.

How heavy are fire doors?

FD30 fire doors weight approximately 45kg. FD60 fire doors weigh upwards of 75kg, so you can see why it is so important that the door opens and closes safely.

What does intumescent mean?

Intumescent means “to expand”. In a building sense, an intumescent product is used to describe a passive fire product that expands when in contact in heat.

What are intumescent made of?

Intumescent products are based on three basic materials:

  • Clay
  • Silicate
  • Graphite
  • These are the active elements of intumescent products.

Clay was widely used in the early days of passive protection but is now only used in specific areas. Clay-based intumescent has a tendency to become brittle with age, and are unsuitable for use in intumescent door strips, as the intumescent material could breakdown and fall out.

Graphite used in intumescent is similar to that used in pencils and is the most commonly used form of intumescent

What does E,EI and other fire-resistant classes mean?

Fire protection regulations are comprehensive, complex and diverse. The fire protection standards of building structures called for by each particular supervisory body vary according to type and use of the building, architecture, as well as the specific installation situation.

These diverse regulations and requirements for the use of fire-resistant glazing have led to the definition of the European standardised fire-resistance performance classification which comprises three classes.

E – Integrity

I – Insulation

W – Radiation

Though the common classifications used are E and a combination of EI and EW. Normally the fire resistance classification is followed by a number which is the limit in minutes, such as 15, 30, 45, 60, 90, 120, 180, 240, or 360. This shows the time the performance criteria is fulfilled during a standardized fire test.


Class E – Integrity

Fire-resistant glass which remains transparent in the event of fire offers protection from fire and smoke but does not reduce the transfer of dangerous radiant heat in the event of a fire (integrity only performance).


I – Insulation

The insulation is classified by the letter ‘I’ and is the ability of a separating element of building construction when exposed to fire on one side, to restrict the temperature rise of the unexposed face to below-specified levels.


W – Radiation

The radiation is classified by the letter ‘W’ and is the ability of the element of construction to withstand fire exposure on one side only, so as to reduce the probability of the transmission of fire as a result of significant radiated heat either through the element or from its unexposed surface to adjacent materials.


Class EI

Fire-resistant glass in this category offers the highest level of protection from fire, smoke and radiant heat for a defined period of time (from 30 up to 180 minutes).


Class EW

Glass in this category offers an integrity performance (protection from fire and smoke) whilst reducing the transfer of dangerous radiant heat.

What is the Regulatory Reform (Fire Safety) Order?

The Regulatory Reform Order (Fire Safety) 2005 (FSO) came into force on 1 October 2006. It gives responsibility to those who are best placed to look at fire safety and ensure that risks – which change over time – are regularly reviewed. Under the FSO a ‘responsible person’ (usually the owner, employer or occupier of business or industrial premises) MUST carry out a fire risk assessment. Responsible persons under the Order are obliged, following a risk assessment, to implement appropriate fire safety measures to minimise the risk to life from fire; and to keep the assessment up to date (this and further information about the Regulatory Reform (Fire Safety) Order is available at:

What is fire resistance?

The fire resistance of a component, such as a steel column, is its ability to resist the effects of fire for a period of time and this is usually measured by submitting the component to a fire test as defined in a nationally or internationally recognised standard.

What is Approved Document B to The Building Regulations for England and Wales?

Approved Document B (ADB) is a Fire Safety document that provides practical guidance on meeting the requirements of the Building Regulations. There may also be alternative ways of achieving compliance with the requirements of the Building Regulations. For a copy of Approved Document B click here

This is a Fire Safety document that gives practical advice & guidance on meeting the Building Regulations requirements.

What do flame retardants do?

Flame retardants inhibit the spread of flames across a surface.

Class 0 & Class 1 spread of flame (BS476 -parts 6 & 7).

Class 0 is a fire propagation test, which means that the coated material not only prevents the spread of flame across its surface but also stops the fire from penetrating into the material for up to 13 minutes.

Class 1 is granted when a fire close to the material only blackens at the point of contact and does not allow the fire to spread across it.

How will Passive Fire Protection Products Help me?

This will never happen we hope the worst-case scenario of a fire roaring through your building. Most people are familiar with the basics of fire suppression such as sprinklers and fire extinguishers, but passive fire protection actually contains a fire at its point of origin. Despite its name, it’s always at work and based on compartmentation of fire and preventing collapse through structural fire resistance, when properly installed and maintained, your building’s passive fire protection can save lives and assets, and the building itself.

They provide precious time to evacuate a building in a fire. The time which could literally mean the difference between life and death.

What is Passive Fire Protection?

Passive fire protection is the first line of defence in preventing the spread of fire. As opposed to active fire suppression, such as fire extinguishers and sprinkler systems, passive fire protection doesn’t actively put the fire out.

Its aim is to contain the fire and smoke within a compartment of the building, allowing the safe evacuation of the property, and preventing further damage to the structure. If the location of the fire prevents the evacuation of all areas, then passive fire systems provide protection to any trapped personnel allowing the fire brigade to attend the scene and effect the safe removal of those trapped.

An important piece of fire protection advice to remember is that passive fire protection can, and does, save lives as well as property.

Why do metal pipes need fire protection?

Although metal pipes don’t burn they are good conductors of heat. An intumescent pipe wrap/collar is used to cool the pipe, prevent heat being transferred through the protected structure element, and igniting another fire on the other side.

Third Party Certification Schemes: Why should I use a third party certificated contractor to install passive fire protection systems?

Approved Document B (Fire Safety) to the England and Wales Building Regulations states “Since the fire performance of a product, component or structure is dependent upon satisfactory site installation and maintenance, independent schemes of certification and registration of installers and maintenance firms of such will provide confidence in the appropriate standard of workmanship is provided.

Why do services access openings thoroughfare rated walls need sealing?

Fire, smoke and hot gases will pass through gaps thus spreading the fire to adjacent parts of the building and consequently become a threat to life.

Whats the difference between fire integrity and fire insulation?

The Integrity (Known as class ‘E’) is the ability of an element of building construction, when exposed to fire on one side, to prevent the passage of flames and hot gasses through it to the unexposed side. Whereby, the Insulation (known as the class ‘I’) is the ability of an element of building construction, when exposed to fire on one side, to restrict the temperature rise of the unexposed face to below specific levels.
