EPS is created in a two-stage process:Raw beads are expanded using steam, creating pre puff beads, which are then cured in large bags before being conveyed to the mold. These include recycling directly into new building products and incineration to recover its inherent energy content. Block… Through testing and years of experience we maintain that extruded polystyrene insulation is superior for use in walk-in coolers and freezers. XPS is most commonly used as foam board insulation. Expanded (EPS) and extruded polystyrene (XPS) are both made from polystyrene, but EPS is composed of small plastic beads that are fused together and XPS begins as a molten material that is pressed out of a form into sheets. le polystyrène extrudé est meilleure car il est plus dense, 35 kg de densité au m3 au lieu de 15 pour l'expansé. Within a short time, Forma became a market leader in Expanded Polystyrene products through its focus on product innovation, good customer service, and expanded capacity. … Expanded polystyrene boards are lightweight, highly resistant to moisture (but not fully water impregnable like extruded polystyrene), durable and are expected to remain effective for many years. performance of expanded (EPS) and extruded (XPS) polystyrene foam insulation in a side‐by‐side, below grade application following a continuous 15‐year installation period. The Long Term Thermal Resistance (LTTR) of XPS is therefore less than its "initial" R-factor. This means that it is rigid foam, so is ideal for securing to external walls. The two types of boards have different technical properties. First, you need to know the materials. Parfois les panneaux sont rainurés ce qui permet de garantir une meilleure étanchéité à l'air aux joints quand ils sont bien posés. See for yourself the performance advantages of Extruded Polystyrene (XPS) vs. XPS is most commonly used as foam board insulation. Is polystyrene insulation any good? The simplest recycling involves crumbling the old EPS into small pieces and remolding them into usable shapes. XPS foam has a tightly packed closed-cell structure that makes it extremely rigid and strong, making it ideal for structural panels. Différence entre un polystyrène expansé et un polystyrène extrudé.

There are many ways you can insulate your homes, whether it's to help retain the heat or prevent cold air from getting in. The 2 lb EPS is available in any … EPS is 90% air because it is not very dense – the fact that it is made up of lots of small polystyrene beads means that there are lots of tiny air pockets. 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. Heat or steam is then applied to the mould which expands the polystyrene beads and fuses them together. But in the case of extruded polystyrene, the polystyrene resin beads or granules are fed into an extruder, where they are heated at very high temperatures until molten. Expanded polystyrene and extruded polystyrene are both made from polystyrene, but EPS is composed of small plastic beads that are fused together and XPS begins as a molten material that is pressed out of a form into sheets. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam. XPS and EPS, manufacturing-wise but also performance-wise represent two different groups of rigid thermal insulation materials. Since density affects the physical properties of the polystyrene and cost it is important to understand what densities are most suitable for which construction applications.

Polystyrene vs. Polyurethane Garage Door Insulation. Refer to the data sheet link for additional information on EPS properties. Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. Expansion of the beads is achieved by virtue of pentane gas, a blowing agent, which is entrapped in the expandable beads. If the water freezes into ice, it expands and can cause polystyrene pellets to break off from the foam. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. The extruded foam then cools and expands into it’s final shape. 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. 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. EPS can be recycled in many ways once it comes to the end of its life. Expanded polystyrene typically holds a higher R-value than extruded polystyrene. Sitemap Privacy Contact Us © 2019 TrueFoam Limited. Le polystyrène extrudé est beaucoup plus dense que l’expansé (en moyenne 2,18 lb pour l’XPS vs 0,93 lb pour le PSE). All Styrofoam products possess a rigid closed cell structure with very unique properties including low thermal conductivity, high resistance to water penetration and high compressive strength.

This manufacturing process involves melting together the plastic resin and other ingredients. Extruded Polystyrene (XPS), is manufactured via an extrusion process where plastic resin and other additives are combined and extruded through a die. Polystyrene itself is a form of plastic, a polymer that can be extruded (think Styrofoam®) or expanded. The outstanding shock absorbency of expanded polystyrene packaging guarantees the protection of products. EPS (Expanded Polystyrene) Vs Polyurethane. The Difference between Expanded Polystyrene and Extruded Polystyrene. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material. In other words, it has a higher insulation performance factor, which makes it very suitable for areas that require more insulation like attics, walls and basements.

When it comes to concrete and insulation, contractors tend to be most familiar with extruded polystyrene (XPS). Finally, XPS is often branded by its manufacturer and frequently comes in a number of different colors which have nothing to do with performance. The heat from the steam in the pre-expansion phase causes the gas to expand, forming perfectly closed cells of EPS. Bonne journée, bkl. Expanded polystyrene (EPS), is produced from small beads of polystyrene that are fed into a mold. Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), commonly called "Blue Board" manufactured as foam continuous building insulation board used in walls, roofs, and foundations as thermal insulation and water barrier.
