Expanded Polystyrene (EPS) Insulation

What is EPS?

When it comes to insulation materials, you cannot go wrong with Expanded Polystyrene Insulation or EPS. This innovative insulation solution has been around for over half a century, since the 1950s, and has become increasingly popular for its superior insulating properties.

EPS is a closed-cell insulation material that comprises 98% trapped air and only 2% plastic. This impressive ratio allows the material to be highly efficient in terms of insulation, using a minimal amount of raw material. It is worth noting that the trapped air in EPS serves as an insulator, reducing the transfer of heat that can make your home or building uncomfortable.

EPS is also a highly versatile material that can be used for a wide range of applications, from insulating walls, roofs, and foundations, to packing materials, and even as decorative crafting material. Overall, EPS is an excellent choice for anyone looking for a reliable, efficient, and versatile insulation material.

Water Resistant:

Expanded polystyrene (EPS) is an incredibly effective insulation material for a number of reasons, one of which being the fact that it is non-hygroscopic, meaning that it doesn’t readily absorb moisture from the surrounding atmosphere. The reason for this is thanks to the closed-cell structure of the material, which greatly reduces the amount of moisture that can be absorbed or migrate into the insulation. This characteristic makes EPS one of the most reliable and low-maintenance insulation materials available on the market today, and is one of the reasons that it is so widely used in a variety of applications, from building construction to packaging. When you choose EPS for your insulation needs, you are making a choice that is both effective and practical, helping to ensure that your insulation will perform as intended for years to come.

Product Durability:

Expanded Polystyrene (EPS) is an exceptional and reliable material that is highly durable and resistant to rot. When specified and installed correctly, it has the capacity to withstand harsh environmental conditions and extreme temperatures for an extended period of time. The unparalleled characteristics of EPS ensure that it remains effective for the entire useful life of any application. Moreover, EPS is a permanent material that does not deteriorate or break down over time, providing added assurance that it will remain intact for years to come. With a lifespan of up to 100 years, EPS delivers exceptional long-term value and sustainability. Its capacity to withstand wear and tear without any deficiency effects only reinforces EPS’s reputation as a high-performance material that can be relied upon for a wide range of applications.
