Why Geofoam Should Be Part Of Your Green Construction Projects
Green construction projects are booming, with an increased demand for buildings and structures that are environmentally responsible and utilizes resources efficiently. It’s important to stay in touch with climate change and the ever-changing state of the environment. Here are some reasons why geofoam should be used in your next eco-friendly project.

Increased Energy Efficiency
As the green construction industry flourishes, the demand for energy-efficient buildings is becoming widespread. In their aim towards LEEF certification, construction site managers are aiming to design the finest infrastructure with the smallest carbon footprint. Automated lighting, heating, and cooling systems, and smart house technologies are quickly becoming the new cornerstone for building development. Geofoam is increasingly being utilized to move towards the concept of sustainability, as well as to strengthen the foundation of energy efficiency. It is the preferred insulating material for projects like green roofs, pools, and general insulation. Geofoam aids in the reduction of energy loss as it is a lightweight and durable EPS material that serves as an effective thermal barrier, preventing internal and external air transfer.

Promotes Sustainability and Energy Conservation
Along with the rise in green construction comes the trend of engaging more sustainable and energy-conserving resources. Vegetative green roofs constructed with geofoam are one such example. Green roofs are completely or partially covered with plants grown on top of a waterproof membrane. In fact, some green roof designs include extra layers providing a root barrier, as well as a drainage and irrigation system. Geofoam has contributed to green roofing by assisting property owners and governments in developing planet-saving rooftop gardens that enhance air quality and produce for healthy living. Two other environmental advantages are stormwater management and temperature regulation. As for consumers, green roofs are good insulation, which lowers energy expenses and increases the roof’s lifespan, allowing them to save on replacement costs.

Withstands Extreme Weather Conditions
With climate change comes catastrophic weather conditions which have been occurring on a regular basis, wreaking havoc on both business and residential structures. Geofoam is being utilized more than ever before to construct structures that can withstand harsh and often unpredictable weather events like floods, earthquakes, and hurricanes. Insulated geofoam structures are much more resistant to emergency conditions as compared to stick-built structures. This material is also more resistant to strong winds and the detrimental effects of natural weather phenomenon. Furthermore, they are more resistant to earthquakes and fire as a result of the concrete structures they are built into.
Lessens Long-Term Environmental Impact
Geofoam blocks do not contain harmful dyes, formaldehyde, chlorofluorocarbons (CFCs), and hydrochlorofluorocarbons (HCFCs). They will also not leech into the ground in the long term. The geofoam manufacturing process does not use or release potentially hazardous greenhouse gases. The process also includes steam, and the water involved is always reused. Geofoam is also 100% recyclable and can be made with up to 10% recycled materials. Using it in a project in place of a naturally derived material like rock and wood ultimately helps with sustainability efforts.

How Is Geofoam Used in Concrete Construction?
Have you already heard about why expanded polystyrene geofoam is so popular in the construction industry? If you have not, we would like to tell you all about this useful material and why it is so crucial in so many construction applications.

The convenience, flexibility, efficiency, and versatility that expanded polystyrene—also referred to as EPS—geofoam has contributed to the wide variety of construction applications has undoubtedly facilitated the transformation of the construction industry in numerous different ways. Expanded polystyrene geofoam has assumed the role of a better type of filling material, the physical attributes and properties of this unique material have also assisted in paving the way towards new kinds of innovation.
Expanded polystyrene geofoam has allowed landscape designers, engineers, builders, construction contractors, and architects to keep themselves in line with the latest, most innovative trends in their own respective industries. Allow us to tell you all about the wonders of using geofoam in concrete construction and how this material is revolutionizing the construction industry.
Expanded Polystyrene Geofoam is the Most Popular Kind of Lightweight Filling Material
Numerous different construction applications call for the use of filling material that is supportive and durable. For instance, traditional filling materials that are lightweight and have been utilized in embankment construction comprise materials such as cellular concrete, seashells, and sawdust. In an effort to lower the levels of strain that are exerted on surrounding environments, numerous engineers have begun to use lightweight filling materials to remedy such situations.
Its highly lightweight nature is more than capable of assisting in the reduction of manual labor and the minimization of any future maintenance works. This helps to ensure a much faster construction schedule. Not only is expanded polystyrene geofoam extremely lightweight, but it also possesses a low rate of moisture absorption and a very high level of compressive strength. This makes the material more than capable of withstanding compression and issues of wear and tear in the long term.
Expanded Polystyrene Geofoam Widens the Scope of Possibility in Construction
Expanded polystyrene geofoam has proven itself to be an extremely useful construction material that has multiple purposes. This is due to its low-density and lightweight physical characteristics, in conjunction with its high rate of compression. It is truly incredible how much efficiency and flexibility this material is capable of providing to builders, engineers, and architects.
Expanded polystyrene geofoam is utilized in a variety of different construction projects, such as insulation, slope stabilization, seating in stadiums, and road embankments, just to name a few. This material is capable of acting as a protective filling material that will provide protection against the potential damages that can be caused by extreme temperatures and shocks from earthquakes, among other external pressures and natural factors. This material is also able to serve as an effective dampener for ambient noises and vibrations.

The Expanding Role of EPS (Expanded Polystyrene) in Roofing Construction
Roof construction is one of the biggest and most significant disbursements that are made by owners of buildings. These important investments generally comprise of repair, maintenance, installation, insulation, a waterproofing membrane, and a roof deck. Designers of roof systems and contractors have been coming to the realization that roofing systems that make use of expanded polystyrene, which is also referred to as EPS, are capable of fulfilling building requirements that are highly demanding.
Expanded polystyrene is a resilient, lightweight, closed-cell insulation made of foamed plastic. It can offer dimensional stability, robust resistance to water, a long-term R-value, and substantial savings on energy expenditures when it is installed in a proper way and protected from the effects of moisture. Expanded polystyrene insulation is a good match with all the commercial roofing systems. Some examples of these expanded polystyrene-compatible roofing systems are modified bitumen, built-up roof, which is also referred to as BUR, and one-ply membrane systems that are fully adhered, mechanically fastened, or ballasted.
Applications of Expanded Polystyrene
Now, you might be wondering: what are the exact applications of expanded polystyrene, in terms of roof systems? Allow us to elaborate!
Tapered Roof Systems
Insulation for a tapered roof can assume an important role in the good and proper draining of roofing systems, which is highly essential to optimal levels of longevity and performance. The poor and improper drainage of commercial roofing systems can lead to damage that is much more severe than natural events such as strong winds or other types of natural phenomena. Freezing and thawing cycles, along with the ponding of water, have the potential to lead to expensive repair works and perhaps even the premature failure of a roofing system, which is very infrequently covered by insurance or under warranty. Tapered EPS insulation is capable of providing the positive slope that is needed while maintaining the economic and structural benefits that come with a roof deck with a low slope.
Built-Up Roof (BUR)
Expanded polystyrene has been consistently utilized in the applications of built-up roof systems for a period of over three decades. Built-up roof systems that are made with roof decks of concrete will allow for roof insulation to be directly applied to a deck. This is because there is not a need for a thermal barrier, which is due to the concrete deck that is not combustible. Expanded polystyrene foam can be joined to concrete with asphalt by using a technique that is referred to as the “mop and flop.”
Asphalt that has been heated to a high temperature is applied directly to the concrete deck, and it is then allowed to slightly cool, prior to the foam being permanently put in place. After this is done, a cover board is then “mopped and flopped” directly onto the expanded polystyrene insulation, with the joints taped and overlapping. Asphalt is then applied again on the top of the cover board, and this will provide a consistent and uniform base for the weatherproofing system.
Suitable Alternative
The current shortage in other insulating materials like Polyisocyanurate (poly-iso) insulation have made EPS a sustainable and efficient alternative.
Engineered EPS (Expanded Polystyrene) insulation is a suitable Poly-iso replacement. EPS provides several technical advantages over Poly-iso. Some contractors may claim that Poly-iso has a greater R-value, which is true when talking about published R-value, but Service R-value is a different story. Poly-iso’s R-value drops considerably as it ages, according to Long-Term Thermal Performance (LTTP). Further research has revealed that the R-value of Poly-iso falls when the temperature drops, which is when R-value is most needed. When it gets cold, EPS’s R-value changes only by increasing its effectiveness. This is only one of the many advantages of EPS vs Poly-iso.
