  • FRA = Fire Retardant Additive. Grades with the additive have 0% recycled material.
  • ECO 40 - Low Density Insulation Grade
  • ECO 70 - Medium Density Insulation Grade
  • ECO 100 - High Density Insulaton Grade
  • ECO 150 - Extra High Density Insulation Grade

EPS Insulation Fire Testing (when using the FRA addtitive)

In April 2018, tests to the EN 13823 and EN 11925-2 standards were carried out by material testing experts Exova Warringtonfire, to determine the classification of our Expanded Polystyrene Insulation (FRA).

(This covers both our sheet insulation and loose-fill cavity wall insulation.)


Samples of different depths of expanded polystyrene containing flame retardant additive were tested, achieving the following result: Euroclass C-s1-d0* (on depths of 20mm-200mm)

Polystyrene Insulation Guidance

Care must be taken when installing PVC cables, to ensure that they do not come into contact with polystyrene insulation.

A chemical reaction takes place between the PVC sheath and the polystyrene, resulting in a migration of polymers with the cable, known as 'marring'.
