Electrical installation duct
safeguards escape and rescue routes

PYROMENT®-IK90, developed by G+H Insulation, is the first electrical installation duct (I-duct) to actively dampen cable fires and thus minimize consequential damage and costs. If a fire should start in a cable duct – due to a technical defect, for example – it could spread for several hundred meters through conventional ducts, in the worst case scenario. PYROMENT®-IK90 can prevent this kind of damage.

The I-duct comprises a galvanized or stainless-steel sheet with a special intumescent insulation sheath and a top coating. In a fire, the insulation sheath foams up immediately, thus – in contrast to conventional electrical installation ducts – actively stopping the spread of fire within the ducts. PYROMENT®-IK90 is the first electrical installation duct to be approved throughout Europe.

Best possible cable protection in escape routes

In addition to stopping the spread of cable fires to the surroundings, PYROMENT®-IK90 also prevents the formation of hazardous smoke. This ensures that escape and rescue routes are kept clear for the evacuation of people and for the fire service.

The duct’s thin, lightweight material makes it quick to install, easy to retrofit and easy to fix in place, even in confined areas where access is difficult.
