The Isover U Protect insulation system for passive fire protection in HVAC applications is now available in an increased choice of insulation thicknesses.

The U Protect system comprises of two products, U Protect slabs or U Protect wired mats; as well as a range of accessories, which ensure effective fire protection and a straightforward installation. Manufactured from ULTIMATE, an innovative and lightweight mineral wool, the U Protect slabs and wired mats combine the advantages of conventional thermal and acoustic insulation with excellent fire performance.

Tested under EN 1366-1 and EN 1366-8, and assessed against BS 476: Part 24, the U Protect system offers up to two hours’ fire resistance in HVAC ventilation and smoke extract ducts, and one-hour fire resistance for kitchen ducts.

Emmanuel Dupuis, Product Manager Technical Insulation at Isover said: “A critical risk when designing a building is the potential spread of fire within HVAC systems. As a result, it is vital that the right insulation for HVAC applications is chosen at the specification stage, in order to ensure the fire safety of a building’s ventilation, kitchen and smoke extraction ducts.

“U Protect is a fully integrated system, delivering passive fire protection for rectangular and circular ductwork and offering a range of benefits for both the installer and specifier. For example, there is no need for intumescent paint or adhesive between each insulation joint – instead it is only required at floor or wall penetrations. This results in cost and time savings during installation, without affecting the system’s overall fire protection.”
