IKO enertherm EPS insulation for inverted roofs is manufactured from an innovative expanded polystyrene (EPS) with low water absorption properties.

The IKO enertherm EPS roof insulation range of products is approved to ETAG 031 (European Technical Approval Guidelines). It is supplied in 200 and 300 grade boards to meet the specified compression performance.

An inverted roof construction places thermal insulation above the waterproof layer. This maintains the waterproof membrane at an even temperature and protects it from the damaging effects of UV radiation or the effects of the weather.

The specified thermal performance of the inverted roof is achieved through the roof design and the thickness of the insulation used. The thickness of insulation required to achieve a specified U-value depends on a number of factors.
