Effective Fire Protection



Smoke, heat and flames represent major fire risks to building users. How materials behave in a fire - from ignition to flashover and fully developed fire - therefore needs to be optimised from the design stage with the correct choice of HVAC insulation materials.

Whether you are looking to protect a school, hospital, shopping mall, office or residentials building, ISOVER has developed a range of HVAC insulation solutions that provide efficient insulation for HVAC pipes and ductwork. Using ISOVER HVAC insulation materials ensures your building is thermally protected and noise disruption is kept to a minimum. These ISOVER HVAC insulation solutions also provide a reliable, affordable and long-lasting guarantee for fire safety.

Passive fire protection for your HVAC pipes and ducts  
For more than 30 years, we’ve been working closely with the construction industry and fire safety experts to develop high-performance passive fire insulation for metal ducts and pipes across your building. This means ensuring that, in a fire, the HVAC components remain stable, prevent the passage of flames and smoke and keep the temperature down for as long as possible. All ISOVER HVAC products are rated as non-combustible and do not contribute to fire or create any toxic smoke or burning droplets. 

ULTIMATE™ HVAC fire insulation

To take fire protection to a new level, our R&D teams have developed ULTIMATE™, a new-generation mineral wool insulation that uses breakthrough technology to combine the performance and handling benefits of glass wool with the outstanding fire resistance of stone wool.

ULTIMATE™U PROTECT HVAC insulation materials are non-combustible, do not contribute to the ignition of fire and do not emit any smoke and burning droplets.

Find the right ULTIMATE™ U PROTECT HVAC insulation materials - whether slabs, wired mats or pipe sections - for your project. Covering different types of pipes, rectangular and circular ventilation and smoke extraction ducts, the U Protect range offers a complete solution with excellent, lightweight thermal and acoustic properties, as well as low maintenance costs.
What exactly is ULTIMATE™ mineral wool?
ULTIMATE™ mineral wool has excellent thermal, acoustic and fire-resistance properties thanks to a unique internal micro-structure.  The long, light, elastic fibres can be compressed and, once installed, retain their properties and thickness over time, even when exposed to vibrations and thermal shocks.
