This 100mm IKO Enertherm PIR board suits numerous applications including external walls, pitched roofs, floors, internal walls, inverted roofs, metal roofs, and flat roofs, delivering outstanding thermal performance in each scenario. The superior insulation properties boost energy efficiency and reduce heat loss throughout your building, whatever the end use. Improved energy efficiency means lower heating and cooling costs, a significant benefit given today's energy expenses. These boards are also eco-conscious, containing no CFCs, HCFCs, or HFCs, so they pose no environmental risk.

About

Pairing the 100mm PIR insulation board with Roof Membranes is straightforward, and the boards maintain their thermal performance and structural integrity over extended periods thanks to excellent dimensional stability. The material resists rot and mould growth, guaranteeing extended service life. With high thermal values and slim profile, 100mm Enertherm boards minimise overall build thickness, maximising usable space in roofs, floors, and cavities.

Micro Cell Technology

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

Shape retention: IKO Enertherm boards maintain dimensional stability and shape consistency longer than PIR Boards with larger cell structures. This prevents thermal bridging and extends service life whilst preserving insulating properties.

Moisture resistance: MCT technology in 100mm IKO insulation boards delivers very low long-term water absorption (< 0.6%) compared to alternative insulation products. The PIR boards stay rot and mould-free, maintaining their R-value since water absorption does not increase weight.

Pressure insulation: 100mm IKO PIR boards withstand significant compressive loads due to their high elasticity. MCT technology provides flexible cells that resist rupture and prevent permanent indentation even under foot traffic.
