Suppressing the spread of fire throughout a building is of vital importance in devising a fire safety strategy. ROCKWOOL fire stopping products are designed to get down to the details, covering every joint, imperfection of fit and opening that could otherwise potentially allow the passage of fire, smoke and hot gases.

In combination with the excellent passive protection offered by fire resilient stone wool, our specialised slabs, cavity barriers and comprehensive sealing and coating range cover all bases. 

The full ROCKWOOL accessories range also includes intumescent pillows, pipe wraps and collars, cable firestops, putty pads, sleeves and wrap rolls. 

Find out how ROCKWOOL solutions can protect occupants in your building – and neighbouring constructions – today. 

Why do we need fire stopping solutions?

A typical building contains a much higher volume of combustible products than 50 years ago, including plastics. 

In addition, HVAC ducts, pipes and other fixtures tend to pass through the compartment elements of a building, creating voids through which flames, smoke and hot gases can spread, if not properly protected. 

Our firestop insulation and specialised products can be used to close the gaps where fire and excess heat could potentially pass to other areas. They are designed to prevent the spread of fire, toxic smoke and hot gases around the building, as well as to neighbouring structures.


ROCKWOOL fire stopping products are:

  • Tested to the highest fire safety standards
  • Durable and easy to install
  • Specifically developed for definitive applications

Calculator and savings

Depending on the size of the build or renovation, you’ll require different amounts of products such as sealants and pipe fittings, as well as insulation boards and slabs.

Any structure, building segment or service unit insulated with ROCKWOOL fire stopping solutions will protect this segment as a proper fire barrier.

Case study

The Grange University Hospital is a new £350m hospital in Cwmbran, Wales. This state-of -the-art facility forms part of a wider strategic plan which will see Aneurin Bevan Health Board significantly modernise its health service provision.

A typical hospital will have between 20,000 and 40,000 firestops. At Grange University Hospital, approximately 25,000 penetration seals were installed using certified products from the ROCKWOOL FIREPRO® Range.
