performance than Polyisocyanurate (polyiso). Q: Can the Federal R-value Rule mislead specifiers regarding the actual thermal performance of rigid The material standard that defines properties for all XPS and EPS is ASTM C578.₆ It requires that polystyrene insulation
When building or renovating a high-performance building envelope there are really three main kinds of rigid foam panels you are going to have to choose from - Polyisocyanurate known as Polyiso (PIR), Extruded Polystyrene (XPS) - often called Styrofoam - and Expanded Polystyrene (EPS).
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. During the life of these foams, air from the atmosphere diffuses in and the trapped gases diffuse out.
EPS boards are for use as a Most of the time EPS and polyiso are about the same 8-10 cents per square foot (EPS) products - Specification.

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.
• Expanded Polystyrene (EPS), ASTM C578. • Extruded Polystyrene (XPS), ASTM C578. • Polyisocyanurate (Polyiso) Extruded polystyrene board (XPS or "blueboard") has a slightly higher R-value than EPS and is more resistant to moisture. Polyisocyanurate board ("polyiso") Jul 22, 2018 The cost for polyiso is currently between XPS and EPS, around $.50 per square foot for one inch thick insulation.
EPS, XPS or PIR for EWI? 2 September, 2013 @ 20:13 · Filed under Westacre I’m having second thoughts about using Polyisocyanurate (PIR) boards for our external wall insulation (EWI).

Expanded Polystyrene, referred to as XPS, is a closed cell insulation product commonly used in remodeling and new construction applications. 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.

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 The difference between Polyiso, EPS & XPS Foam Insulation & Styrofoam We always choose (and recommend) EPS over XPS due to the fact that XPS has much higher greenhouse gas emissions than EPS. So if you are looking for suggestions we would say go for the EPS, and if you want added protection, source one with a foil backing.
