What is EPS? What is EPS Foam?

Teknopor EPS “expanded polystyrene foam” is an economic and lightweight thermal insulation material derived from petroleum in the form of foam, generally white thermoplastic consisting of 98% air and 2% plastic with closed porous structure.

Small polystyrene granules are heated with water vapor and expanded by inflating with pentane gas, an organic component. The pentane gas in numerous small closed pores, which form in the granules, is replaced by air during production and within a short time after production. After dried in special silos and inflated with water vapor again, the granules stick firmly to one another without any gaps and take the shape of the mold they are in, resembling honey combs; thus, EPS thermal insulation blocks known as EPS foam or EPS Styrofoam are formed.

This motionless and dry air, which is trapped in the granules with small closed pores, enables EPS thermal insulation to provide superior thermal insulation for buildings. Dry and motionless air within numerous granules constituting EPS does not create thermal bridges, and ensures excellent thermal insulation by preventing heat loss.

Teknopor EPS Products

Teknopor is the brand for EPS products of Teknopanel. Graphite Teknopor is the brand of EPS thermal insulation boards produced with the addition of grey graphite.  Graphite Teknopor gains infrared absorption and reflectivity features with its graphite addition, and increases thermal insulation performance by reducing the material’s thermal conductivity value. 

Teknopor EPS products are used in various parts of the buildings from basis to roof and from wall to floor. Alongside Teknopor and Graphite Teknopor Thermal Insulation Boards, the products manufactured under the brand of Teknopor are Teknopor Perforated Thermal Insulation Board, the light filler material used in building concrete floor Teknopor Light Filler Blocks, Teknopor Geotek Subsurface Filler Blocks used in the construction of highways and bridges, and EPS Jamb Block used as exterior trimming material. 

Technical Properties of EPS Foam

Having a durable and robust structure, EPS products are among the most practical and economic materials when applied in accordance with the standards and in correct thickness and density according to their usage area and the climate of the region.

The fact that EPS products can be manufactured in various densities facilitates to present products with the desired technical values. The motionless air in small closed pores which constitute EPS product ensures low thermal conductivity and high thermal insulation values. It is also dampproof, steam-tight, and repels water.

Environment-friendly EPS products are flexible and have a durable structure against temperature changes and time. Therefore, they do not show dimensional changes such as extension or shortening. They are also quite resistant against mechanical factors. Thanks to their lightness, they do not put extra load on the structure they are used in.

As an end product, EPS has features such as lightness, free-machining and usability in the manufacturing of other composite products together with other materials.

Advantages of EPS

  • Low thermal conductivity value provides high thermal insulation.

The lower EPS thermal insulation boards’ thermal conductivity value is, the more thermal insulation they provide. Thermal conductivity value of EPS boards reduces as their the density and thickness increase. As the pentane gas within EPS thermal insulation boards is replaced by dry and motionless air, its thickness does not change significantly when used under load for a long time. It preserves its low thermal conductivity value, and continues to provide e􏰂cellent thermal conductivity.

  • It has high mechanical compressive strength.

When preferred with the correct thickness and density according to its usage area, EPS thermal insulation board show a superior mechanical strength against long-term loading and impacts, and does not lose its thermal insulation value.

  • It repels water, prevents humidity and bacterial growth.

Granules of EPS thermal insulation boards sticking firmly to one another and having close pore structure ensures that the board has a very low water absorption rate when it contacts with water. Thanks to its water-repellent structure, none of its features change even though it contacts with water.Close porous structure is resistant against condensation in the air, and does not allow transmission of humid air. It prevents humidity and moisture, as well as the corrosion of load-bearing system accessories. Moreover, it prevents humidity, microorganism growth and mold in interior environments. Therefore, it protects human health.

  • It has high dimensional stability.

Thermal insulation materials should have high dimensional stability. Dimensional change in buildings may occur due to thermal expansion in consequence of the effect of different temperatures, as well as independently of external factors within a certain period of time after production. Dimensional stability should be considered separately according to temperature and time.The dimensions of EPS thermal insulation materials at the time of application are not deformed due to thermal and mechanical effects within time. Having a high dimensional stability, EPS is an ideal material thanks to its resistance against seasonal changes. This provides an important advantage for civil engineering applications.With its high compressive strength, EPS offers features that do not change according to load and time for floors, traffic areas, classroom and lecture hall floors and road embankments.

  • Its lightness is an advantage.

EPS offers a considerably advantageous weight/volume performance compared to other building materials in construction sector. As its closed porous structure consists of 98% air, it is light, and does not place additional load on buildings. It is easy to load and stack.

  • It is an economic solution.

The cost of EPS products for construction sector is lower by approximately 1/3 compared to other alternative products. It provides a minimum cost advantage of 20% compared to mineral wools(rock wool and glass wool). It also comes to the forefront as the most appropriate material in terms of maintenance expenses of existing buildings.The strength of EPS is high although it is a light material. It has low labor cost as it is easy to carry and can be installed quickly. Moreover, it contributes to the reduction of gas emission with low transportation costs and low fuel consumption.

  • It is heat and cold resistant.

Thermal insulation materials are expected to show a long-lasting and non-decreasing performance against heat and cold. Maximum resistance of EPS against high temperatures depends on the degree and duration. EPS can be used until 75-85 oC at maximum and -180 oC at minimum according to density and environmental conditions over the long term. This resistance feature increases the number of areas EPS is used.

  • It is fireproof.

As per TS EN 13501-1, EPS boards are classified as materials having a minimum fire performance of “E” and consisting of raw materials defined as B1 flame proof. When EPS thermal insulation boards are used as components of exterior thermal insulation systems outside of buildings, they have a fire performance of B. When used coated with materials such as plaster, alum or plasterboard, it is included in the fire performance class of the coating material used on it, because it is not in direct contact with the source of flames.

  • It is easily shaped and processed.

EPS thermal insulation boards inflate in the form of granules with the process applied at the final stage of production. The inflated granules take the shape of the mold they are in. EPS board produced as blocks can be easily cut in required shapes after production.

  • It provides excellent thermal insulation.

Thanks to the dry and motionless air in its closed pores, EPS provides e􏰂cellent thermal insulation. It is applied in zones where thermal bridges may occur, and surround the building in all sides. It plays an important role in reducing the building’s energy consumption by cutting down heating expenses in winter and cooling expenses in summer. Therefore, it does not increase environmental pollution as it uses less fuel.

  • It is installed quickly and easily.

EPS application is quick and easy thanks to its flexible and lightweight structure. Therefore, it saves time and keeps labor costs low.

  • It has a flexible structure.

Air pockets in EPS’ pores provide cushioning by serving as a buffer. It absorbs the force of impacts or pressure, prevents contracting or stretching in temperature changes, and is not fragile.

EPS Foam Prices

EPS (Styrofoam) prices varies from the type of the product to be used to its technical features and sizes. EPS thermal insulation products are more economical compared to other construction materials with the same performance. You can save by preferring Teknopanel EPS products for the needs of your construction such as insulation foam, Styrofoam, EPS thermal insulation materials etc.
