Fire penetration products are designed to seal gaps and voids formed by piping, cables, wall spaces and other services which penetrate compartment walls and floors, where flames and smoke could spread in the event of a fire.

We offer a comprehensive selection of products that have been specifically engineered to combat fire spreading – buying valuable time for occupants to escape and for fire services to arrive.

This can raise the overall fire safety standards of a building, and offer additional protection for those living and working there.

Fire Penetration Products

Why do we need fire penetration solutions?

Fire penetration products perform a vital role in protecting buildings from fire and smoke spread.

Pipeworks, electricity cables and network lines keep buildings running every day. But both they, and the gaps around them, can be the perfect places for fumes and flames to pass through in the event of a fire.

This spread can happen in a matter of seconds. Not only does this put lives at risk, but it also minimises the time emergency services have available to arrive at the scene and provide help.

Installing robust fire resilient insulation and other specialised products is an effective way to help prevent this.

Any chain is only as strong as its weakest link, and ROCKWOOL solutions are designed to strengthen these weak points. By plugging gaps around cables and pipes, as well as through solid, partition and light construction walls, fire safety in constructions can be significantly improved.

Calculator and savings

To calculate how much of each product you’ll need, you can contact us directly. We can work with you to understand your construction and the unique needs of your building.

Once installed, effective insulation, seals and wraps can help create a safer working and living environment for occupants – and protect constructions against costly damage.

Case studies

The challenge

Sluseholmen Karré K in Copenhagen, Denmark is a 168-flat apartment block. A high level of fire resilience for the building’s ventilation ducts was needed to ensure the safety of residents – and complement the appearance of the building.

The solution

ROCKWOOL Conlit fire boards were installed to boost the non-combustible properties of the building. These tight-fitting stone wool products help plug any haps where fire or smoke can spread if a fire breaks out.

The results

Conlit products used throughout the ventilation ducts, and sealed using technical insulation tape, obscure joints and protect against the threat of fire to improve resident safety.

FAQs

FAQs

How do you seal a wall penetration?

When fire penetration products are installed in walls or floors, pipe penetrations can be insulated with our pipe section range. The annular gaps/voids around the penetration seal are sealed using Acoustic Intumescent Sealant for an optimal solution. For floor constructions, dependent upon the annular gap/void, these can be sealed using Firestop Compound or Acoustic Intumescent Sealant. 

Consult the FIREPRO Standard Details guide for specific information to suit the penetration type and application.

 

What is a ‘through penetration’?

A through penetration is a gap that completely passes through a barrier such as a wall or floor. This means both sides need to be sealed.

What is fire stopping?

Fire stopping is the process of preventing and slowing fire spread around penetrations of a construction, such as pipes or cables. This is achieved using fire resilient insulation and specialised products.
