IKO EPS 300 E Insulation Board

IKO EPS 300 E Insulation Board

IKO EPS 300 E Insulation Board for inverted roofs is manufactured from an innovative expanded polystyrene (EPS) with low water absorption properties.

Approved to ETAG 031 (European Technical Approval Guidelines), IKO EPS is supplied in both 300 E and 200 E grade boards to meet the specified compression performance. IKO EPS 300 E is graded A in the BRE Green Guide.

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 weather.

The specified thermal performance of the inverted roof is achieved through the roof design and the thickness of the insulation used.
