IKO enertherm PIR insulation, quality lies in the details

IKO enertherm’s specific composition gives it a number of characteristics that are superior to those of other rigid foam boards. This makes IKO enertherm the most energy-efficient insulation with the longest service life, without the loss of its insulating qualities.

Thin board thickness, optimum performance

IKO enertherm insulation has the highest performance per m². This means that a higher insulation value is achieved with a thinner board thickness than with other insulation materials (such as EPS, XPS and mineral wool). With IKO enertherm, you therefore make optimum use of the space available on the roof, in the floor or in the cavity.

Dimensionally stable

Better mechanical properties are achieved than with coarser foam because of the fine cell structure. This makes the insulation boards dimensionally stable and the insulating capacity is retained for years.


At around 32 kg/m³, IKO enertherm is a lightweight insulation. This generates ergonomic benefits in the handling of the material.


IKO enertherm insulation achieves a fire classification of B class s2, d0 (end use). The board produces very little smoke and does not melt or drip. The fire retardant properties are characteristic of the chemical structure

Less volume

The thinner board thickness of IKO enertherm for the same insulation value compared with other materials means a more limited volume of insulation boards is needed, resulting in lower transport costs.


IKO enertherm has very low water absorption and is rot- and mould-proof. As a result, the insulation value is retained under all conditions.
