Kaiflex railCLAD (R1 HL3)
Halogen-free, this insulation product provides active protection by expanding when exposed to heat

Benefits & Attributes

According to EN 45545, in the event of a fire, the protection and safety of passengers and personnel should be awarded the highest priority. To ensure this, it is first and foremost necessary to prevent the spread of fire and the development of smoke gas which is hazardous to health.

Kaiflex railCLAD is a halogen-free elastomer composite with a very high insulation effect and smoke-restricting, fire-proof foil cladding. The insulation product provides active protection by expanding when exposed to heat, thus closing or shielding holes and preventing the fire from spreading to the next carriage or compartment. This also allows flammable substrates to meet the component inspection requirements of R1 HL3. The halogen- and heavy-metal-free materials prevent the development of toxic gases and dust particles in the event of a fire. This is particularly important in the case of railway vehicles that spend the majority of their travel time in underground sections with restricted evacuation conditions.

Kaiflex railCLAD also minimises energy losses and, thanks to its UV resistance, it is particularly suitable for exterior applications. The insulation product complies with all regional and national railway vehicle standards.

  • Excellent thermal values minimise energy loss
  • Weather & UV resistant for outdoor use
  • Durable protective covering
  • Effective sound barrier performance reduces noise breakout
  • Fire protection standard compliance
Excellent thermal values minimise energy loss
Kaiflex features a low thermal conductivity that prevents the loss of energy from pipework making Kaiflex an excellent insulating material.
Weather & UV resistant for outdoor use
Insulation used outdoors must be capable of withstanding sun, rain, wind and snow without suffering degradation. Kaiflex is available with a range of weather resistant coverings pre-applied for outdoor use.
Durable protective covering
Insulation is easily damaged by deliberate or accidental impact. Durable protective coverings minimise damage to the insulation and simultaneously provide a maintainable surface finish.
Effective sound barrier performance reduces noise breakout
High density materials prevent the passage of noise, encapsulating it and preventing breakout.
Fire protection standard compliance
Kaiflex rail products comply with the European fire protection standard EN 45545 for railway vehicles. Kaiflex RailCLAD and rail LSLT comply with the highest requirements of the NFPA 130 standard
