Expanded Polystyrene EPS or EPS (Expanded Polystyrene) or airpop is a material, one of the most widely used internationally, used in construction industry from the foundations to the roof. It is a light and rigid insulation material made of plastic foam, which is produced by compact polystyrene particles. Due to the fact that it is 98% air, in recent years the term airpop has been established in Europe to describe the expanded polystyrene.

EPS expanded polystyrene products:
- They offer excellent thermal insulation properties while they maintain low weight as they consist of 98% trapped air.
- They have structural stability and they do not decompose. EPS stress tests for about 30 years of use underground have shown that it always exceeded the minimum required limit of 100 kPa. EPS used in bridge foundations that had undergone stressing for about 40 years indicated less than 1.3% distortion. The stability of the EPS is not affected by time.
- They present small resistance coefficient values in water vapor diffusion (μ) and they are capable to “breathe”, preventing the vapor condensation formation phenomenon.
- They are perfectly combined with most building materials (cement, plaster, anhydrite, organic and inorganic mortars).
- They can contribute to proofing from airborne and impact sounds.
- They are manufactured for building uses as self-extinguishing (SE) as its mass contains flame retardant.
- They offer a perfect price – efficiency balance and are economically advantageous.
- They are also fully recyclable and environment friendly.
The EPS products are applied to a building from its foundations to its roof, indicative application fields:
- Roofs (coating of storeys – pilotis spaces, concrete panels, conventional & inverted roof)
- Floors (residences and underground levels)
- Walls (double stretcher bonds, complex exterior heat insulation/ETICS systems, wall dividers, insulating concrete forms/ICF).
- Inclined rooftops (internally or externally).
- Underground levels (around the circumference of the wall dividers internally or externally, floors, foundations).
- Civil engineer projects (seismic isolation, road construction works).
