XPS Foam

The Ultimate Thermal and Moisture Insulation with Unmatched Performance in the Building Industry

XPS foam, or extruded polystyrene, is recognized as one of the most popular thermal insulations in the world due to its closed-cell structure.

This foam boasts a moisture absorption rate of 0.2%, thermal conductivity of 0.003%, and compressive strength ranging from 200 to 500 kPa, establishing it as a leading choice in the insulation industry. Its closed-cell structure prevents water absorption and penetration, making it a reliable thermal insulation material for all building surfaces.

Due to its high density, XPS foam offers exceptional resistance to water and vapor, remaining stable without any loss of quality under extreme temperature changes and freeze-thaw cycles. This product is suitable for use in a temperature range from -50 to +75 degrees Celsius and maintains excellent performance even in humid conditions.

This moisture-resistant insulation leads to buildings with longer lifespans and optimized energy consumption, providing a healthy and sustainable living environment.

Polystyrene

Polystyrene is a synthetic polymer made from styrene monomers. Styrene is used as a key component in the production of various plastics and is also naturally found in some foods like strawberries, cinnamon, and coffee.

Polystyrene is typically a transparent thermoplastic that can be produced both as a solid and as a rigid foam. In its natural state, polystyrene is transparent, hard, and brittle, but its properties can be modified with additional materials to create a range of products.

History of XPS Foam

XPS (Extruded Polystyrene) foam was invented approximately 70 years ago and remains one of the advanced technologies in the world. This insulation plays a key role in optimizing energy consumption in both industrial and residential buildings. For instance, despite its vast size and high population, China has an energy consumption similar to that of Iran, largely due to the widespread use of XPS foam in construction and industry.

The United States, as the first country to produce XPS foam, pioneered this technology globally and, alongside Russia, is among the largest producers of this insulation. Due to its thermal properties and high resistance to moisture, XPS foam continues to be a primary solution for optimizing energy use in many countries.

This article can further address recent developments in XPS foam production, such as improvements in manufacturing processes and increased performance against temperature and moisture fluctuations. Additionally, the expansion of XPS foam use in environmental and sustainable building projects across various countries can be highlighted.

Components of XPS Foam

XPS insulation is composed of a blend of non-expanded polystyrene (similar to beads) and gases such as R22, CO2, or butane. The production process of this insulation is carried out through extrusion; this involves melting the polystyrene, injecting gas, and combining it with specific additives. The mixture is then extruded through a mold to form sheets of the desired thickness.

Applications of XPS Foam

XPS foam, or extruded polystyrene, has widespread applications and is used globally. This product is applicable in various parts of buildings, including basements, floors, walls, foundations, flat roofs, and façades. It is also employed in infrastructure and industrial projects such as roads, dams, railways, airport runways, cold storage facilities, mobile units, military installations, and clean rooms.

XPS Foam in Building Construction

XPS foam is used as a thermal and moisture insulation material in various parts of buildings. It is applied in basements, walls, roofs, and façades. Due to its high resistance to moisture and temperature fluctuations, XPS foam provides excellent performance and long-lasting stability. It also helps prevent energy loss and optimizes energy consumption in buildings.
