eps vs xps insulation

Thermal Insulation ANSI/SBCA FS200 Standard Requirements for the Testing, Design and Application of Foam Plastic Insulation Used as Sheathing for Building Enclosure Applications The FS200 standard 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). Extruded Polystyrene (XPS) Usually defined by the blue, green or pink color, XPS falls in-between Polyiso and EPS in the range of price and performance. 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. Your price comparison is consistent with the trend.

TECHNICAL BULLETIN. XPS & Polyiso. Long-Term Thermal Resistance. & R-Value Performance. For XPS, polyiso, and closed-cell spray foams, the blowing agent is a gas the polystyrene (XPS) and polyiso insulations, while expanded polystyrene (EPS) Most of the research on the market compares EPS, XPS, Polyiso and Mineral Wool, because they've been readily available on the market. One you may not It may be a code violation to install any foam board (eps, xps, poly iso) against interior walls without a fire barrier.

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. Expanded polystyrene (EPS) •The most versatile of the three rigid insulation options. •Used in Roof, Wall, Floor, Below Grade & Structural GeoFoam applications.

For example, XPS foam board has a maximum shrinkage rate of two Nov 3, 2017 The Polyiso gives it up a bit to the XPS right at the 50 degree mark A good alternative is type 2 eps hs40 at r5/inch highly compressible and Sep 7, 2016 However after digging down the insulation rabbithole further, I've read that polyiso insulation performs poorly if it gets wet and that extruded (xps Extruded polystyrene, and Polyisocyanurate w/ foil face. Tribu built his Kubic camper using XPS polystyrene sandwiched between two thin Even EPS seems less water absorbent than XPS. Can't say the same about polyiso. I wouldn't want my life raft to be a polyiso board. Polyisocyanurate foam (PIR) is essentially an improvement on polyurethane where there is a slight difference in the constituents and where the reaction is 2 feb. 2021 — XPS vs.
