Insulation
It has been estimated that the effective application of EPS insulation could cut carbon dioxide emissions by up to 50%.
EPS Insulation Benefits
Expanded Polystyrene (EPS), is a highly beneficial insulation material that is widely used in both commercial and residential construction applications. It possesses several characteristics that make it a good insulator:
Low thermal conductivity:
EPS has a closed-cell structure composed of tiny spherical cells filled with air. Air is a poor conductor of heat, and the trapped air within the EPS cells hinders the transfer of thermal energy, thereby reducing heat flow. This low thermal conductivity helps to maintain a temperature gradient and insulates against heat transfer.
Moisture resistance:
EPS is non-porous and does not readily absorb moisture. Moisture can be a conductor of heat, but the closed-cell structure of EPS prevents the movement of water molecules, reducing the chances of thermal bridging or heat transfer via conduction.
Lightweight and easy to install:
EPS is lightweight, making it easy to handle and install as an insulating material. Its lightweight nature also allows it to be used in various applications without adding significant weight to the structure.
Cost-effective:
EPS is relatively inexpensive compared to other insulating materials, making it a cost-effective choice for insulation projects. It provides a good balance between cost and thermal performance.
Versatile:
EPS insulation is available in different forms, including rigid boards, molded shapes, and loose beads. This versatility allows it to be used in various applications, such as walls, roofs, and foundations.
Resistant to mould and pests:
EPS is made of a material that is not a food source for mould, pests, or rodents. This inherent resistance makes it a favorable choice for insulation, as it helps prevent the growth of mould and the infestation of pests.
Insulation Applications
EPS insulation is commonly used in a variety of applications due to its excellent insulating properties and versatility. Some of the main applications of EPS insulation include:
Building insulation:
EPS is widely used for thermal insulation in residential, commercial, and industrial buildings. It can be used in walls, roofs, floors, and foundations to reduce heat transfer, improve energy efficiency, reduce noise, and provide a comfortable indoor environment.
Cold storage and refrigeration:
Expanded polystyrene is highly effective in maintaining low temperatures and is used in cold storage facilities, refrigerators, freezers, and other applications where temperature control is critical. Its insulating properties help prevent heat ingress, ensuring efficient cooling and preservation of perishable goods.
HVAC systems:
EPS insulation is used to insulate air ducts, HVAC (Heating, Ventilation, and Air Conditioning) equipment, and pipes. It helps to prevent heat loss or gain during the distribution of conditioned air, improving energy efficiency and reducing operating costs.
Insulated concrete forms (ICFs):
EPS foam panels are used as formwork in the construction of ICF walls. These panels provide both insulation and structural support, resulting in energy-efficient buildings with enhanced strength and durability.
Geofoam:
EPS is used as lightweight fill material in geotechnical and civil engineering applications. Geofoam is utilized to reduce the load on underlying soils, provide slope stabilization, and insulate roads, bridges, embankments, and airport runways.
Packaging:
EPS is commonly used in packaging applications due to its lightweight nature and cushioning properties. It provides excellent protection and shock absorption, making it ideal for shipping fragile and delicate items and products that require temperature control.
