expanded polystyrene in construction

It has an incredibly long lifespan – up to 50 years. No gases are included. EPS exhibits a higher R-value over moist-dry cycles, most often seen in below-grade applications, outperforming XPS insulation and providing a long-term R-value to the project. It is dependent upon the thickness and density of the building material. First, the resin beads are fed into a vertical tank containing an agitator and a controlled steam input. This stage determines the final density of the material by controlling the length of time the beads remain in the expander and/or the pressure in the expander. Published on August 1, 2018 January 9, 2019. Moreover, a study commissioned by the EPS Molders Association found that the R-value of EPS geofoam does not decrease with age, even under freeze-thaw conditions, whereas other insulation materials can lose R-value over time. The long-term performance advantages of EPS insulation correlate directly to increased energy efficiency and reduced energy costs over the life of the building. It is extremely lightweight, but strong and durable. A closer look at: Expanded Polystyrene Expanded Polystyrene (EPS) has become known for its role in smaller combustible cladding fires over the last 20 years due to its very flammable composition. In fact, several different types of EPS geofoam can be specified on a single project to maximize savings. Copyright 2012 © EPS Industry Alliance. A versatile building material, it works well for a variety of different applications such as road construction, bridge abutments, slope stabilization, building foundations, retaining walls, stadium and theatre seating, fill for underground utilities and landscaping and insulation for both above- and below-grade applications. The simplest recycling involves crumbling the old EPS into small pieces and remolding them into usable shapes. However, many organic solvents such as acetone, chlorinated solvents and aromatic hydrocarbon solvents can attack the foam and cause it to dissolve. Its Health House Indoor Air Quality guidelines recognize EPS geofoam as a safe material for insulation and structural support in construction projects. 9325 Sky Park Court, Suite 250 Energy efficiency. EPS geofoam is water resistant and can inhibit the growth of these organisms. It is extraordinarily light and buoyant, and a good insulator against heat and sound. And, it isn’t attractive to rats and other vermin as a source of food. Up to 10% of recycled EPS geofoam can be used in the manufacturing process. Pentane, a hydrocarbon solvent, is typically used as the blowing agent during the manufacturing process. Unlike the R-value, in which the higher the number, the better, a material with a lower perm rating is better at retarding movement of water vapor. San Diego, CA 92123, Distributor of Expanded Polystyrene block for use in construction applications throughout the world, All Rights Reserved - Geofoam International LLC |, Expanded polystyrene, or EPS geofoam, is a cost-efficient insulation material used in the construction industry. It is among the few insulating materials with a … Higher densities of EPS geofoam have a greater comprehensive strength than lower densities. But that rating may be misleading. The R-value of EPS geofoam insulation remains constant because the closed-cell structure of EPS geofoam contains only stabilized air. Durability. EPS geofoam is manufactured using primarily steam, and even the water from the manufacturing process is collected and reused. Expanded Polystyrene (EPS) is a lightweight cellular plastic material consisting of small hollow spherical balls. In 2016, more than 118.7 million pounds of EPS geofoam was recycled in the U.S. You’ll find recycled EPS geofoam in everything from insulated cups to outdoor furniture. The EPS insulation had a moisture content of 4.8%, compared to an 18.9% moisture content for the XPS insulation. The compressive resistance of EPS geofoam at 1% deformation ranges from 2.2 psi to 18.6 psi. Sustainability. Expanded Polystyrene Used in Bridge Construction EPS products, including flute fillers, Terraflex Elasticized Polystyrene, and EPS Geofoam are used in road and bridge construction throughout the … EPS foam offers exceptional dimensional stability. Plus, EPS foam insulation can be fabricated to size or cut into any configuration to fit a specific project’s needs. Cost. The Eps stand for Expanded Polystyrene.This is a modern, efficient, safe and economic construction system of buildings. Since the 1950s, EPS has been … One pound of EPS geofoam will support 3.5 pounds per square inch while retaining 1% or less deformation. And, far more energy is saved over the lifetime of a building insulated with EPS foam board than is used during the manufacturing process for producing the product. … Expanded Polystyrene has been the proven answer to common packaging, insulative, and construction material solution for decades. And, it isn’t attractive to rats and other vermin as a source of food. EPS geofoam’s strength is even more amazing considering it is so lightweight. With a wide range of compressive resistance strengths to choose from, it’s easy to find a solution for most every project. These building panels are often used both as load bearing also as non-load … High compressive strengths of up to 60 psi make EPS durable and long-lasting and able to stand up to harsh conditions without deterioration. Plus, the product itself doesn’t emit any greenhouse gases. EPS geofoam is one of the most environmentally responsible building materials you can specify in your construction project. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam. However, many organic solvents such as acetone, chlorinated solvents and aromatic hydrocarbon solvents can attack the foam and cause it to dissolve. At about $0.31 per square foot for a one-inch thick panel, EPS geofoam costs less per square foot than any other rigid foam board insulation product. Since EPS geofoam isn’t biodegradable, it won’t leach into the ground over time, adversely affecting soil and groundwater quality. Buildings insulated with EPS geofoam insulation are more economical to maintain over the years. Lightweight expanded polystyrene (EPS) is an ideal material for pre-fabricated building … It is also resistant to microorganisms in the soil. Home  |  News & Announcements  |  Contact Us  |  Related Links  |  Privacy Policy, Production, Technology & Operations Conference. Expanded Polystyrene is Growing in the Construction Industry with the Rise of Pre-Fabricated Housing. One pound of EPS geofoam will support 3.5 pounds per square inch while retaining 1% or less deformation. During this phase, recycled EPS material is mixed with the prepuffs and is also fused into the material. Moisture promotes the growth of many organisms such as mold, mildew, fungi and other bacteria. Like … In 1965, the first expanded polystyrene (EPS) block molding plant was established in Grand Rapids, Michigan. EPS geofoam’s strength is even more amazing considering it is so lightweight. There are two reasons why Molygran can provide construction and engineering solutions. It is used for the … EPS geofoam weighs in at only one to two pounds per cubic foot, depending on size. Using EPS Geofoam in Retaining Wall Construction, Using EPS Geofoam to Reduce Weight in Utilities. Polystyrene can also be used as part of temporary shuttering to create shaped concrete to match any existing or new building designs. In the second phase, the expanded beads, called prepuffs, are dried in the open air for several hours and then, in the third phase, they are transferred to large storage silos. EPS geofoam also has the seal of approval from the American Lung Association. Expanded polystyrene, or EPS geofoam, is a cost-efficient insulation material used in the construction industry. Since EPS geofoam is a thermoplastic material, it will not rot or decompose over time. It’s lightweight, meaning products … Getting the maximum performance for the dollar is paramount in the competitive arena of the construction industry. Firstly, expanded polystyrene has qualities essential to engineering and construction … Because a molding process is used to produce EPS foam, there are more sizes available to select from, compared to XPS foam board which comes in limited sheet sizes.
