Expanded polystyrene or EPS is a thermoplastic foam material that we produce from solid beads of polystyrene whereas the extruded polystyrene or XPS is a foam material that we produce from solid polystyrene crystals. Polyurethane is a new product with roughly 35 years of testing. It is a rather poor barrier to oxygen and water vapour and has a relatively low melting point. Remember that expanded polystyrene is simply lighter, thicker, and less insulating than extruded polystyrene. whether it’s a stage play or a shop display case to be decorated, these panels can act as false partitions and create a specific atmosphere if they’re dressed up. Your email address will not be published. However, it’s worth noting that expanded polystyrene panels are more suitable for decoration: they’re lighter and less expensive. Polystyrene has a typical R-value of approximately 4.4 per 1″ thickness of material. XPS is primarily used in the form of blue panels for insulating floors and roofs (flat). Saint-Jean-Baptiste Montréal (Québec) H1B 5V3. It’s therefore preferred in areas with rather extreme weather conditions. General-purpose polystyrene is clear, hard, and rather brittle. While XPS is "extruded" into a close approximation of its final form, EPS is manufactured in large blocks that are subsequently cut by hot-wire machines into sheets or cut into virtually any special shape or form by computer-driven systems. For example, it’s equipped with a higher mechanical resistance than EPS. Polystyrene panels are primarily used to insulate houses, but they can also be used in the creation of sets for artistic projects, for example. The EPP manufacturing process is complex. However, grey polystyrene is slightly more expensive. on average for XPS vs. 0.93 lbs. Polyurethane has been developed to alleviate the shortfalls of EPS. Required fields are marked *. Saint-Jean-Baptiste Montréal (Québec) H1B 5V3. window.mc4wp = { window.mc4wp) { on: function (event, callback) { These include recycling directly into new building products and incineration to recover its inherent energy content. Expanded Polystyrene – EPS. The main difference between these two materials lies in their density. Molded Pulp vs. These qualities are especially appreciated in Québec. Polystyrene is commonly injection molded, vacuum formed, or extruded, while expanded polystyrene is either extruded or molded in a special process. } Expanded Polystyrene (EPS) EPS is a kind of rigid, tough and closed foam. XPS cells contain insulating gases in addition to air that eventually diffuses out of the cells, thus lowering the insulating value. The simplest recycling involves crumbling the old EPS into small pieces and remolding them into usable shapes. It is a light-weight and rigid foam, which is produced from solid beads of polystyrene. Unique Properties of EPP. The R-factor of EPS remains constant over the life of the product because the manufacturing process used in EPS results in normal air, rather than gas, in the voids in the product. The battle began, EPS versus XPS, and the test results are in. The difference between EPP and EPS lies in the manufacturing process where the distinctive resin (polypropylene vs polystyrene) goes through a different process under tightly controlled conditions. It’s also less expensive and more manageable for those who don’t have machines adapted to its cutting. These repeating units are “monomers”. 2 lb nominal density EPS (expanded polystyrene) has become a very popular alternative to extruded polystyrene for under slab and perimeter foundation wall insulation. Your email address will not be published. Expanded Polystyrene (EPS) is one of the most economic and cost-effective options for insulating your home. It is commonly understood that XPS offers more initial R-value per inch than EPS but because of its lower cost, EPS offers more R-value per dollar. What is Expanded Polystyrene or EPS Polystyrene Foam? Polystyrene panels are very useful when it comes to decorating a place. This was clearly shown in an independent, third-party test. Save my name, email, and website in this browser for the next time I comment. 5025, boul. Extruded polystyrene is much denser than expanded polystyrene (2.18 lbs. EPS is one of the most commonly used PS foam in everyday life. But these two products could not be more different. Insulfoam is a division of Carlisle Construction Materials, a wholly owned subsidiary of Carlisle Companies (NYSE: CSL), and is the nation's largest manufacturer of block-molded expanded polystyrene (EPS). callback: callback This is a relatively simple project that can reap great benefits, but with the wide variety of approaches you can take to insulate your garage, how do you choose the one that is right for you? A SCULPTURE ENLARGEMENT FOR THE WINNER OF THE LAST SCVLPTVRE SHOW, 100,000$ INVESTMENT FOR NEW TECHNOLOGY AT USIMM. Expanded polystyrene maintains its R-Value even after long-term exposure in northern climates. forms : { Although the same material they manufactured differently; EPS beads are molded or cut into various sizes and shapes while XPS is extruded sheets. The white foam is commonly used for … FMI-EPS | Learn the difference between Expanded Polystyrene (EPS) & Extruded Polystyrene (XPS) See why EPS holds a better R-Value compared to XPS Expanded Polystyrene has been used for approximately 50 years. It must also be noted that stated R-values of insulations products vary under different conditions and truly credible comparisons must take into consideration the specific brands of foam and specific test conditions. Cost. Because EPS insulation is 98% air, it is chemically inert. The Long Term Thermal Resistance (LTTR) of XPS is therefore less than its "initial" R-factor. EPS has been with us for around 50 years. window.mc4wp.listeners.push( Sitemap Privacy Contact Us © 2019 TrueFoam Limited. Since XPS is typically more expensive than EPS, buyers need to closely compare the tables of properties for each product as compared to the needs of the application. The food service industry is a major user of this product, which makes strong, protective, and insulating trays, cups, and containers. Expanded Polystyrene (EPS) Insulation is a rigid closed cell plastic foam that is comprised of hollow, spherical beads that are fused together using steam. EPS (Expanded Polystyrene) Vs Polyurethane. Plaster is often used with expanded polystyrene and combined in the form of a plate. If it’s only handled a little, expanded polystyrene will largely do the trick. Expanded polystyrene (EPS) is the winner! Polystyrene can be solid or foamed. For example, whether it’s a stage play or a shop display case to be decorated, these panels can act as false partitions and create a specific atmosphere if they’re dressed up. Lightweight, they’re very easy to transport. Its lightness makes it easy to handle and install. { The Advantages of Expanded Polystyrene EPS is a … XPS & EPS Differentiators. Generally, polystyrene is a synthetic aromatic polymer made from the monomer styrene, which is derived from benzene and ethylene, both petroleum products.Polystyrene can be solid or foamed. By: Agence Combustible|Published on: Nov 2, 2017|Categories: News, Uncategorized| 0 comments. Polyurethane is a relatively new product, roughly around 35 years. An extremely cost effective packaging material, it is moisture resistant, a good thermal insulator, (insulation R-value of 4.0 per inch) and it is structurally strong (compression strength of 1000 lbs per square foot.) Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. For over 50 years, Insulfoam has been enabling building professionals to construct high-quality building insulation systems at a minimal cost. On the other hand, if this element needs to have a minimum resistance, then it will be better to opt for extruded polystyrene. The 2 lb EPS is available in any thickness, not just 1″ increments and is more economical than extruded polystyrene. EPS (expanded) and XPS (extruded) are both closed-cell rigid insulation made from the same base polystyrene resins and manufactured differently, EPS is beads that are molded or cut into various sizes and shapes while XPS is extruded sheets. Puffed polystyrene beads are used for several different applications besides the manufacture of EPS … In addition, it’s not necessary to use a highly insulating material as a decorative element; the cheaper option should be more than sufficient. No, we are not kidding, it is blue in color! Below you will see a detailed difference between polyurethane, and expanded polystyrene. ); XPS performs better than EPS.
