5. Wrap: outside wall insulation (closed joints).
6. Comfort: loft insulation.
7. Comfort Easy: Loft floor insulation.

This 70mm IKO Enertherm PIR board suits numerous applications including external walls, pitched roofs, floors, internal walls, inverted roofs, metal roofs, and flat roofs, delivering superior thermal efficiency. The insulation properties significantly improve energy performance and thermal resistance throughout your building, whatever the installation context. Improved energy efficiency means reduced heating and cooling bills—a real benefit given current energy costs. These boards are also eco-conscious, containing no CFCs, HCFCs, or HFCs, so they pose no environmental risk.

About

Pairing the 70mm PIR insulation board with Roof Membranes is straightforward, and the boards retain their insulating effectiveness and structural integrity over extended periods due to excellent dimensional stability. Rot and mould resistance further extends service life and reliability. The combination of high thermal values and slim profile reduces overall construction depth, maximising usable space in roofs, floors, and cavities.

Micro Cell Technology

IKO Enertherm incorporates distinctive Micro Cell Technology (MCT), achieved through carefully selected raw materials and optimised manufacturing processes. This creates an exceptionally fine cell structure within the insulation.

Shape retention: IKO Enertherm boards maintain their form and dimensional stability longer than PIR Boards with larger foam cells and non-shrinking alternatives. This prevents thermal bridging and ensures extended service life without compromising insulation performance.

Moisture resistance: MCT technology in 70mm IKO insulation boards delivers very low long-term water absorption (< 0.6%) compared to alternative insulation products. The PIR boards resist rot and mould growth, maintaining their thermal value since water-induced weight gain is avoided.

Pressure insulation: 70mm IKO PIR boards withstand substantial pressure loads thanks to their high elasticity. MCT technology provides flexible cells that prevent rupture and resist permanent indentation even under foot traffic.
