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. Your price comparison is consistent with the trend. There may be some typos in your table. At 2" most Type-I EPS is about R7.6-R7.8, not R6.4.
Another difference between the polyiso and XPS insulation concerns ultraviolet light. XPS is degraded by UV light but the facers on polyiso insulation protect the core from such damage. Polyiso is compatible with a large number of roof and wall systems, too.
XPS performs better than EPS. You only have to look See for yourself the performance advantages of Extruded Polystyrene (XPS) vs. Expanded Polystyrene (EPS). With increasing requirements in continuous insulation (c.i.), Architects, Designers and Specifiers are faced with making a choice: Polyisocyanurate (polyiso) or Extruded Polystyrene (XPS). Both of these foam plastic insulations are governed by Chapter 26 of the International Building Code (IBC), yet they are very different in their physical and thermal properties.
It has an insulation products, like XPS, EPS, and Polyisocyanurate foam exterior Rigid panel insulation, also referred to as continuous insulation, can be made from foam plastics such as polyurethane (PUR), polyisocyanurate (PIR) Some, such as expanded polystyrene (EPS) "beadboard", are suitable for grou EPS and XPS are both made from polystyrene, but EPS is composed of small Polyisocyanurate insulation is available as a liquid, sprayed foam, and rigid Polyiso consists of a uniform closed-cell polyisocyanurate foam core and provides one of the highest R-values per inch of any rigid insulation. Filter Products By. Feb 5, 2020 The main insulation is usually polyisocyanurate or EPS; and the second (EPS) and extruded polystyrene (XPS), each with unique properties. Jul 19, 2019 Should the studs butt up against the foundation wall or be set in an inch? Fiberglass? Rock wool? XPS? EPS? Polyiso?
EPS boards are produced by putting the beads into moulds and heated XPS is slightly stronger than EPS, and although it is used in many of the same applications as EPS, it is particularly a closed-cell plastic, is formed by reacting two monomers in the presence of a blowing agent catalyst (polymerisation). Polyisocyanurate
Each type is used in a variety of applications and under conditions where resistance to water and moisture is critical. Polyisocyanurate, also referred to as PIR, polyiso, or ISO, has the highest R-value of any rigid foam board insulation commercially available.It comes with a variety of backers (foil, fiberglass mat, vinyl, and paper), and is very similar to the polyurethane used by spray foam contractors. The trapped gases in the cells of polyiso and XPS foam assist to provide an initial high R-value.
16 nov. 2011 — Polyiso offers increased R-value per inch vs mineral fiber, XPS or EPS options · Designed for use in continuous insulation to assist in meeting
Both EPS and XPS come in compressive strength levels ranging between 10 and 60 psi. XPS also comes in 100 psi options.
Feb 28, 2011 Vapor Barrier. EPS boards are homogenous EPS foam; they have no facings. Polyiso boards have metal (foil) or paper facings, sometimes on
Apr 8, 2015 With that being said, Extruded Polystyrene (or XPS or “Styrofoam”) can only be used in applications up to 165°F, whereas Polyisocyanurate (or
Rigid foam insulation comes in three common forms: expanded polystyrene (EPS ), extruded polystyrene (XPS), and polyisocyanurate (PIR). Sharing the
Apr 24, 2017 EPS - Expanded Polystyrene: Rated at R4 per inch; it's more permeable to air and moisture than XPS. Two inches of EPS has a moisture
Expanded polystyrene, or XPS, extruded polystyrene, or EPS, and polyisocyanurate, or polyiso, are the three main types of rigid, closed-cell insulation materials. Sep 3, 2016 Two of the most frequently installed types of rigid foam insulation are expanded and extruded polystyrene (EPS and XPS).
Inkompensation hvad er
The result is polyiso and XPS lose R-value over their lifetime.
Expanded polystyrene, or XPS, extruded polystyrene, or EPS, and polyisocyanurate, or polyiso, are the three main types of rigid, closed-cell insulation materials.

In conclusion: polyisocyanurate gets top marks for being 'eco' if you can handle its moody disposition. EPS foam is versatile and in the middle ground for performance, financial and ecological cost, and XPS foam is a top performer but comes with some unfortunate baggage.
This testing conclusively found that the XPS (with a published R-value of 5.0 per inch) performs 30 percent better than the polyiso (with a published R-value of 5.6-6.0 per inch) at 50°F mean temperatures. 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. XPS is most commonly used as foam board insulation.
Polyisocyanurate, also referred to as PIR, polyiso, or ISO, has the highest R-value of any rigid foam board insulation commercially available.It comes with a variety of backers (foil, fiberglass mat, vinyl, and paper), and is very similar to the polyurethane used by spray foam contractors.
(XPS). The type Other alternatives are polyisocyanurate (PIR), polyurethane. (PUR) XPS vs. EPS Foam For Foundation Insulation.
EPS, XPS, and Polyiso insulation: we’re going to look into how they are made and compare their physical and chemical properties.Chapters0:00 EPS Expanded Pol The maximum service temperature for EPS is around 170 degrees Fahrenheit. Polyisocyanurate is chemically related to polyurethane, a versatile plastic used for car parts, solid tires, pillows, paints, adhesives, sealants and many other uses.
