Expanded polystyrene (EPS) is used as thermal or sound insulation. It is a light, rigid and closed cell insulation. Expanded polystyrene is available in several compressive strengths to withstand loads and backfill forces. When used on the ground, this closed cell structure ensures minimal water absorption and low vapor permanence.
Commonly used as insulation for walls, foundations and roofs, the choice of expanded polystyrene products has many advantages:
• Long-term R-value (“R” is resistance to heat flow)
• Energetic efficiency
• Constant thermal resistance
• Measurable energy savings
• Strength – Durability
• No bacteria growth or degradation over time
• Dimensional stability
• Chemical inertia
Polystyrene also available in another model called Thermo block in polystyrene.
The polystyrene thermo block that is inserted between concrete beams to create a floor with high insulating power. This expanded polystyrene in the form of white compact foam has, thanks to its texture, excellent thermal, sound and shock insulation capacities.
The polystyrene block is very light and therefore easy to handle, which contributes to a very fast construction (installation of walls and insulation in a single operation). It is very thermally and sound-insulating: no thermal bridges, airtightness guaranteed …
Thermal blocks with polystyrene integrally located between two layers of the high compression concrete aggregate mixture are successfully used for the construction of external walls.
The thermal block saves more than 50% on electricity costs. reduced demand on the air conditioning system.
