Sep 21, 2018 This article provides an overview of polyiso foam insulation to help you such as expanded polystyrene (XPS) or extruded polystyrene (EPS),
2020-06-17 · 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.
Due to the manufacturing process, XPS insulation is typically available only in standard dimension square or rectangular boards. Expanded polystyrene (EPS) EPS is the insulation used most widely in insulated concrete forms and structural insulated panels (SIPs). EPS has the lowest average R-value of the three most common types of rigid-foam insulation, around R-4 per inch. It also is the least expensive. EPS is suitable for ground contact and can be treated to resist insects.
(EPS) INSULATION COMPARISONS EXTRUDED POLYSTYRENE (XPS) POLYISOCYANURATE (Polyiso, ISO) 19727 57th Avenue East • Puyallup, WA 98387 insulfoam.com. Created Date: per inch, with XPS being slightly more efficient, and with Polyisocyanurate having the best R-value per inch. The R-value of EPS foams can be increased by increasing the density of the product, however, the more dense expanded foams are less common in the market. Typically EPS foam has a rated value of approximately R-4 per inch. I think there are two good choices for Exterior Rigid Foam Insulation.
Carlisle manufactures an extensive variety of commercial insulation products that provide increased thermal performance and energy efficiency, including polyisocyanurate (polyiso) insulation and block-molded expanded polystyrene (EPS). Expanded Polystyrene (EPS) Extruded polystyrene (XPS) Polyurethane (PUR/PIR) Expanded Polystyrene is a lightweight, rigid and closed-cell plastic foam insulation material produced from solid beads of polystyrene.

The density of XPS is from 25 kg ~ 45 kg, normal strength from 150 kpa to 700 kpa or higher. The advantages and disadvantages of the two systems: The advantage of eps board: 1) it has line into a system, mature technology. XPS is produced from the same base materials as EPS and therefore also has crude oil at its basis. The production process of extruded polystyrene is only slightly different from expanded polystyrene.
Expanded polystyrene, or XPS, extruded polystyrene, or EPS, and polyisocyanurate, or polyiso, are the three main types of rigid, closed-cell insulation materials. Each type is used in a variety of applications and under conditions where resistance to water and moisture is critical.
XPS versus EPS insulation. XPS and EPS have some key differences: Thermal conductivity: both XPS and EPS provide good thermal conductivity performance. However, the air trapped in the voids in the EPS will conduct heat. Ångdiffusionsmotstånd: ångdiffusionsmotståndet är 30-70 för EPS och 80-250 för XPS. Det innebär att EPS släpper igenom mer luft och fukt, medan XPS har ett bättre motstånd mot vattenånga. XPS passar därför bäst för isolering av fuktiga platser som golv, källare och grundmurar. 2011-02-28 · Polyisocyanurate is chemically related to polyurethane, a versatile plastic used for car parts, solid tires, pillows, paints, adhesives, sealants and many other uses. Polyiso is derived from isocyanate in a complex series of reactions.

Oct 17, 2008 There are three types of rigid foam insulation: expanded polystyrene (EPS), extruded polystyrene (XPS) and polyisocyanurate (polyiso), each
Jan 7, 2019 It is denser than EPS and provides more R-Value with a rating of 5 per inch of Polyiso comes in several thicknesses and is used over house
Sep 12, 2016 EPS and XPS are thermoplastics, while Polyiso is a thermoset foam.

Extruded polystyrene consists of a blended polystyrene polymer heated and ran through an extrusion process. (Facilitiesnet.com) XPS is semipermeable with a perm rating of 1. Most of the time EPS and polyiso are about the same 8-10 cents per square foot per R, and XPS is usually a about 11-13 cents per R-foot.

2011-02-28 · Polyisocyanurate is chemically related to polyurethane, a versatile plastic used for car parts, solid tires, pillows, paints, adhesives, sealants and many other uses. Polyiso is derived from isocyanate in a complex series of reactions. It is mixed with a catalyst to cause a hardening reaction-somewhat like two-part sealants or epoxy glues. Compressive Strength – XPS vs EPS Insulation The compressive strength of insulation is the measure of how well it stands up to pressure before it begins to break. Both EPS and XPS come in compressive strength levels ranging between 10 and 60 psi. XPS also comes in 100 psi options.
