Extruded polystyrene has you covered Durability, reusability, moisture resistance, and the ability to retain R-value in the presence of water enables FOAMULAR XPS insulation to be used in a wide variety of building applications from roof insulation to below-grade use where the insulation will be in constant contact with moisture. styrofoam!). Plywood has been the primary material for model railroad bench tops for many years. Generally, polystyrene is a synthetic aromatic polymer made from the monomer styrene, which is derived from benzene and ethylene, both petroleum products. Although both expanded and extruded polystyrene have a closed-cell structure, they are permeable by water molecules and can not be considered a vapor barrier. Dechow and Epstein (1978) found the 0.2 vol.% water absorption of extruded polystyrene (XPS) foam after 5 years to be much smaller than the 8–30% for polystyrene bead foam (EPS). Almost all of the petrochemical insulation materials are in the form of polymers. 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. D. L. Hetrick, Dynamics of Nuclear Reactors, American Nuclear Society, 1993, ISBN: 0-894-48453-2. To provide a pleasant and positive work environment where individual effort, combined with teamwork and commitment to Foam Products Corporation, is rewarded through professional and personal development.

Apparently it needs to be coated on both foam surfaces then there is a little wait for the glue to firm up, then the two surfaces can be … Main purpose of this website is to help the public to learn some interesting and important information about thermal engineering. Assuming one-dimensional heat transfer through the plane composite wall, no thermal contact resistance and disregarding radiation, the overall heat transfer coefficient can be calculated as: U = 1 / (1/10 + 0.15/1 + 0.1/0.028 + 1/30) = 0.259 W/m2K, qloss = q . Extruded polystyrene foam, also commonly known as XPS foam or the trademarked brand name Styrofoam™, is used to make foam products from building materials like insulation to architectural models. The production process of extruded polystyrene is only slightly different from expanded polystyrene. Extruded polystyrene has a closed cell structure and is often stronger, with a higher mechanical performance and is, in principle, often more expensive than EPS. in a foam-like structure).

Clarendon Press; 1 edition, 1991, ISBN: 978-0198520467, G.R.Keepin. Heat and Mass Transfer. This is the key difference between expanded and extruded polystyrene. Air and other gases are generally good insulators. 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. It can be used for the insulation of buildings, roofs and concrete floors. Of all the types of insulation, extruded polystyrene (XPS) is among the simplest to install. Similarly as EPS, XPS has a wide variety of applications. Gases possess poor thermal conduction properties compared to liquids and solids, and thus makes a good insulation material if they can be trapped (e.g. DOE Fundamentals Handbook, Volume 1 and 2. On the other hand, many plants contain fibres for their strength, therefore almost all the bio-based insulation materials are fibrous (except expanded cork, which is cellular). £1.19 to £9.59. Typical thermal conductivity values for extruded polystyrene are between 0.025 and 0.040W/m∙K. Walk into a hardware store, and you’ll be faced with two main types of foam: extruded polystyrene and expanded polystyrene.Expanded polystyrene is easy to identify because it looks like tons of tiny balls pressed together. Theodore L. Bergman, Adrienne S. Lavine, Frank P. Incropera. Foam Products Corporation offers our clients the highest quality extruded polystyrene with our Styrofoam™ insulation products. FOAMULAR 250 Extruded Polystyrene (XPS) provides continuous insulation in insulated concrete sandwich panel walls, in masonry unit cavity walls, or when used with non-penetrating, surface mounted furring systems over masonry or concrete walls. Styrofoam™ extruded polystyrene is rigid for durability, and will retain its integrity through the installation process and for years to come. In further reading, there is a brief description of these types of insulation materials. Therefore, many insulating materials (e.g. The lower the thermal conductivity of the material the greater the material’s ability to resist heat transfer, and hence the greater the insulation’s effectiveness. Expanded Polystyrene (EPS): Ultimate Guide on Foam Insulation Material For several years, expanded polystyrene (EPS) has been utilized as a material of choice in several food packaging applications, cost-effective and energy-efficient insulation in construction applications as well as cushion transport packaging material for shock sensitive goods and many more. I think you really want extruded polystyrene rather than expanded. A = 105.9 [W/m2] x 30 [m2] = 3177W.

The high quality XPS foam products from FPC can easily be cut and shaped to meet the specifications of your project. As can be seen from the figure, inorganic materials can be classified accordingly: The organic insulation materials treated in this section are all derived from a petrochemical or renewable feedstock (bio-based). It’s 2Lb/cu ft density & pure white. In expanded polystyrene there are interstitial gaps between the expanded closed-cell pellets that form an open network of channels between the bonded pellets. 1) You may use almost everything for non-commercial and educational use.

Fantastic for Warhammer Boards, Hills and scenery. Modelling Foam Made from extruded polystyrene, Craftfoam is a versatile material with many applications such as model making, hobbies, war gaming, floral, product design, art and prototype work. Note that, these convection coefficients strongly depend especially on ambient and interior conditions (wind, humidity, etc.). The Cookies Statement is part of our Privacy Policy. XPS is produced from the same base materials as EPS and therefore also has crude oil at its basis. Its density range is about 28–45 kg/m 3. Polystyrene is commonly injection molded, vacuum formed, or extruded, while expanded polystyrene is either extruded or molded in a special process. Co; 1st edition, 1965. The heat flux can be then calculated simply as: The total heat loss through this wall will be: qloss = q . Polystyrene copolymers are also produced; these contain one or more other monomers in addition to styrene. (Expanded Polystyrene - EPS) orPink Foam - blue pink foam typically used for insulation. 2) You may not distribute or commercially exploit the content, especially on another website. Foamular extruded polystyrene from Austech External Building Products has always been a versatile product.

Extruded Polystyrene has been used extensively for model making, including model railways, model boats, surf boards, architectural modelling, sculptures and table top games like Warhammer. Extruded Polystyrene sheets are 25-100 mm thick, which can be cut and … extruded polystyrene) function simply by having a large number of gas-filled pockets which prevent large-scale convection. The rate of steady heat transfer between two surfaces is equal to the temperature difference divided by the total thermal resistance between those two surfaces. Extruded polystyrene has a closed cell structure and is often stronger, with a higher mechanical performance and is, in principle, often more expensive than EPS. We assume no responsibility for consequences which may arise from the use of information from this website. Its density range is about 28–45 kg/m3. Polystyrene is a colorless, transparent thermoplastic, which is commonly used to make foam board or beadboard insulation and a type of loose-fill insulation consisting of small beads of polystyrene. Owens Corning® FOAMULAR® extruded polystyrene (XPS) insulation is a closed-cell, moisture-resistant rigid foam board with excellent long-term stable insulating performance and durability.
