Non-combustible insulation is vital to help ensure the safety of building occupants, preventing the spread of fire and limiting its structural damage.

A fire can start in any part of a building. That’s why the use of fire resilient insulation throughout the building can reduce the risk. 

Discover our effective solutions – and the benefits of installing ROCKWOOL fire resilient insulation today.

Why do we need non-combustible insulation?

Protecting the lives of buildings’ occupants is the number one priority during a construction or renovation. Fire resilient insulation, made from non-combustible materials, slows down the spread of fire, containing it within one compartment of a building for designed fire periods.

This allows valuable time for occupants to escape during a fire, creating a safer environment for firefighters to combat the fire and rescue people. It also helps to contain a fire and reduce potential widespread damage to the building.  

All buildings should be designed and constructed to fully meet the requirements of UK building regulations.


ROCKWOOL non-combustible insulation:

  • Does not produce any significant toxic gases or smoke
  • Limits fire spread
  • Protects against heat generated in a fire
  • Does not contribute to the development of fire
Fire resilient insulation is a key element in today’s construction projects. Because we do not build or renovate as we used to do 50 years ago, being aware of the possible consequences of this change, like increased fire risks for example, is critical. Non-combustible materials have an important role to play in keeping modern buildings and their occupants safe.

Case studies


The challenge

The Minerva Primary Academy’s ventilation system incorporates an extensive ductwork system featuring both internal circular and external rectangular sections.

To ensure optimum performance for the system, external ductwork sections require effective insulation to protect them from changes in the ambient temperature


The solution

DPR Thermal specified ROCKWOOL® DuoDuct slab and Ductwrap as thermal, noise reducing and non-combustible insulation solutions for the building’s ventilation system in line with the requirements of Building Bulletin 101 (BB101) “Guidelines on Ventilation, Thermal Comfort and Indoor Air Quality in Schools” and Building Bulletin 93 (BB93) "Acoustic Design of Schools" .


The results

“It goes without saying that on any education project the fire safety performance of the product is a critical consideration. We were also looking for a solution that could help minimise any noise transfer in line with BB99. Finally, it makes a big difference if the insulation that we work with is also easy to work with, saves us time and doesn’t cause us any issues on site.” - Daniel Rowan, DPR Thermal
