IKO Enertherm ALU PIR Board 90mm

The 90mm IKO Enertherm ALU PIR Insulation Board delivers high-performance thermal insulation with a rigid polyisocyanurate foam core that contains no CFCs, HCFCs, or HFCs. Both sides feature a gas-tight aluminium facing comprising seven layers of reflective ALU cladding, engineered for superior performance. This 90mm Insulation Board has undergone rigorous testing to confirm its durability against water absorption, mechanical impact, corrosion, and thermal emissivity under demanding conditions.

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 90mm PIR board suits external walls, pitched roofs, floors, internal walls, inverted roofs, metal roofs, and flat roofs, delivering outstanding thermal performance across all applications. The superior insulation properties significantly improve energy efficiency and thermal retention throughout your building. Enhanced energy efficiency means reduced heating and cooling costs—a practical benefit when managing energy expenses. These boards are also environmentally responsible, containing no CFCs, HCFCs, or HFCs, so they pose no environmental risk.

About

Pairing the 90mm PIR insulation board with Roof Membranes is straightforward, and the boards maintain their insulating performance and build quality over time thanks to excellent dimensional stability. The material resists rot and mould growth, guaranteeing extended service life. The high thermal values and slim profile of 90mm Enertherm boards reduce overall construction depth, maximising usable space in roofs, floors, and cavities.

Micro Cell Technology

IKO Enertherm features unique Micro Cell Technology (MCT), achieved through carefully balanced raw materials and production processes. This creates an exceptionally fine cell structure within the insulation.

Shape retention: IKO Enertherm boards maintain their shape and dimensional stability better than PIR Boards with larger foam cells or those prone to shrinkage. This prevents thermal bridging and extends service life without compromising insulating properties.

Moisture resistance: MCT technology in 90mm IKO insulation boards delivers very low long-term water absorption (< 0.6%) compared to alternative materials. The PIR boards remain rot and mould-proof, preserving their insulation value since water absorption does not increase weight.

Pressure insulation: 90mm IKO PIR boards offer exceptional load-bearing capability due to their high elasticity. MCT technology provides flexible cells that prevent rupture and resist permanent indentation even under foot traffic.
