Introduction
The use of cellular polystyrene as Thermal Insulation has become popular due to the good Thermal insulating properties and high strength-to-weight ratio exhibited by panels made from polystyrene resins.also these panels generally are reasonable in cost when compared with their energy-saving potential.

Ecoboard*R is an injected polystyrene insulation board from the Ecofoam* renge of products.it is a specially designed product for Inverted and Conventional Roofing Systems.Ecoboard *R has the following characteristics.

*Low thermal conductivity
*High thermal resistance
*Good mechanical strength
*No aging effects
*Negligibly low moisture absorption
*Resistance to rotting
*No thermal cycling effects
*Homogeneous closed-cell structure

extruded-polystyrene

*When single-layer pvc plastic membranes are used a protection layer has to be applied between the Ecoboard*R boards and the membrane.
