ROCKWOOL fire resilient solutions can slow the spread of flames, contain fires locally and stop them from spreading further.

Robust stone wool insulation is a key component in fire-resilient buildings, as its fibres are non-combustible and can resist temperatures above 1,000°C.¹

The fire protection qualities of our products help increase the safety of occupants – and protect nearby buildings too.

Why do we need passive fire protection?

When building and renovating, protecting people’s lives in the event of a fire is a vital consideration.

In the year ending June 2022, UK fire rescue services in England attended more than 26,000 primary fire incidents in residential properties² - illustrating the need for fire barriers and structural protection to ensure people’s safety.

Approved document B provides guidance on the minimum fire resistance performance depending on the part of the building* ³. The Energy Performance Building Directives (EPBD) now also demands to consider fire safety when renovating buildings ⁴.

Products that meet and exceed national standards can help occupants safely exit a building or remain in a secure place to await rescue.

ROCKWOOL passive fire protection solutions:

Do not produce dangerous toxic smoke
Resist the passage of fire and smoke
Can help maintain business continuity
Help give occupants time to escape

*Depending on the type of property, distance from top floor above ground and depth of lowest basement.

Why choose ROCKWOOL solutions?

Key benefits of ROCKWOOL insulation include:

Fire resilience – ROCKWOOL insulation is extremely resilient to fire. Our stone wool insulation used to manufacture fire cavity barriers and structural fire protection is capable of withstanding temperatures in excess of 1000°C ⁷
Slows spread of flames – average-sized modern rooms can be engulfed in fire within three minutes ⁸– our products slow that progression by containing the fire. ⁹

Prevents fire developing – ROCKWOOL insulation works to contain fire and prevent its spread, helping save lives and stop further property damage. ¹⁰
Robust – ROCKWOOL fire protection barriers compartmentalise fires when they happen, using robust stone wool fibres to contain flames to an area. ¹¹
Smoke toxicity – during a fire, our insulation doesn’t contribute significant quantities of toxic smoke – lowering the risk of smoke inhalation. ^{12 13 14}

Case studies

The project

Queen Elizabeth Olympic Park is a sporting complex in Stratford East London, housing a world-class digital campus: Here East.

Laing O’Rourke converted the former Olympic Press Centre into new office, restaurant and university facilities in 2016.

The challenge

Fire safety was an important consideration during this renovation. Fire protection contractors, Roseville, were tasked with solving the difficulties of installing air sealing and fire stopping products in the intricate building structure.

They chose ROCKWOOL seal strips and fire sealant solutions, using approximately 1,300 linear metres to reinforce the fire resilience of linear joints and service tunnels, such as fire exit routes.

The result

Risk of fire spreading minimised
Fire escape routes secured
People and investments protected

To find out more about our range of fire protection products, consult our product web pages.

Key tips:

Fire stopping barriers may be fitted under compression or utilise support systems which can be fitted to the wall or soffit.
It’s helpful to measure the width and length of the space you’re installing – this will help you know what you need before ordering. If you’re still unsure of what you need, contact our team.
When cutting ROCKWOOL insulation before installing, use a long-bladed knife or an insulation saw.

Installation guides for professionals

The materials we use when renovating buildings must be sustainable, support energy efficiency and be fire safe – using non-combustible materials.

FAQs

What are the fire protection safety rules for insulation?

What is the difference between a fire partition and fire barrier?

Fire partitions are internal walls that can be either load or non-load bearing – providing a minimum of 30 minutes fire resistance. Fire rated divisions must be continued through to the external envelope of the building and fire barriers are mainly used to continue walls and floors out to the external facade or as a continuation of a fire partition, through roof voids to the external roof construction. These products ensure compartment lines are maintained.
