Insulated Panel Core Materials

The core can be made from different types of material with different insulating values, fire ratings, and strengths. The most common are EPS (Expanded Polystyrene), PPS (Phenolic/Polystyrene), PIR (Polyisocyanurate), and mineral fibre.


EPS foam is mainly used for applications where high fire resistance is not a requirement.


PPS may be used where greater fire resistance is required.


PIR foam is increasingly specified because of its fire-resistant properties and better insulation efficiency.

Mineral Fibre

Mineral-fibre insulation may be selected for applications where fire resistance and/or acoustic insulation properties are of prime importance.
