Range Of Applications

1. Rooftop: Flat Roof Insulation for timber, concrete and steel deck.
2. Sarking: pitched roof insulation (type nF with neutral felt).
3. Floor: floor insulation (underfloor heating and concrete floors).
4. Wall: cavity wall insulation.
5. Wrap: outside wall insulation (closed joints).
6. Comfort: loft insulation.
7. Comfort Easy: Loft floor insulation.

This 120mm PIR board suits external walls, pitched roofs, floors, internal partitions, inverted roofs, metal decking, and flat roof systems, delivering outstanding thermal performance across all applications. Enhanced energy efficiency reduces heating and cooling demands, lowering utility costs significantly. The boards contain no CFCs, HCFCs, or HFCs, making them environmentally responsible choices for sustainable building projects.

About

Pairing the 120mm PIR insulation board with Roof Membranes provides straightforward integration while preserving insulation performance and structural integrity throughout its service life. These boards resist rot and mould growth, extending durability and reliability. The combination of excellent thermal values and compact profile minimises overall build thickness, maximising usable space within roof cavities, floor voids, and wall systems.

Micro Cell Technology

IKO Enertherm incorporates Micro Cell Technology (MCT), achieved through optimised material selection and manufacturing processes. This creates an exceptionally fine cell structure delivering superior insulation characteristics.

Shape retention: IKO Enertherm boards maintain dimensional stability longer than standard PIR Boards with larger foam cells. This prevents thermal bridging and ensures sustained performance without degradation of insulating properties.

Moisture resistance: MCT technology delivers exceptionally low long-term water absorption (< 0.6%) compared to alternative insulation products. The 120mm IKO insulation boards remain protected against rot and mould, maintaining their thermal value since water uptake is minimised.

Pressure insulation: 120mm IKO PIR boards withstand significant compressive loads due to their high elasticity. MCT-engineered flexible cells prevent rupture and permanent deformation, even under foot traffic.
