Thermobreak® RT utilises our unique physically crosslinked technology coupled with low emissivity reinforced aluminium foil facing to create an insulation that meets the extensive fire & smoke requirements of transit vehicles whilst providing outstanding thermal performance & moisture protection.



Market Leading Performance

  • Thermobreak® RT has the lowest thermal conductivity of any flexible foam insulation material; 0.032W/mK (23°C) (0.22 @ 73° F).
  • Vapour Permeability of almost zero ensures our thermal conductivity remains relatively constant for a period of 10 years.
  • Thermobreak® RT is extremely lightweight meaning a reduction in the total weight of the vehicle resulting in increased energy efficiency.

Fire & Smoke Safety

Thermobreak® RT offers the highest fire and smoke ratings to meet most major National and International Standards.
