Eps Foam R Value

All of these types contribute to giving you some level of financial payback when it comes to your heating bills.

Eps foam r value.

Eps foam does not use these types of blowing agents therefore its insulation performance remains stable over its entire life. Foam board insulation. R value means the resistance to heat flow. In recent years studies continue to show how eps outperforms xps on all levels of r value.

Below are the results of three research studies performed by the eps industry alliance on the r value of eps vs xps. Eps insulation has found numerous application areas across a wide range of industries due to its light weight and rigidity as well as its thermal resistance properties. Additional r value for a masonry wall constructed using these materials needs to add the insulating value of additional wall components typically included such as 1 solid foam polyisocyanurate r 8 extruded polystyrene r 5 expanded polystyrene r 4 or 1 of perlite r 2 7 and for an exterior air film winter no wind r 0 17 an interior. Eps insulation 1 0 pcf provides a typical r value of 3 85 per inch k factor 0 26 at a mean temperature of 75 f and a typical r value of 4 17 per inch k factor 0 24 at a mean tem perature of 40 f.

Universal foam products provides expanded polystyrene eps products. When you are making a decision between eps and xps and you prefer the higher r value option eps is the answer. While the trapped gases in the cells of polysio and xps foam may provide an initial high r value these products have been found to lose r value over their lifetime.

Eps foam has a solid r value and unlike fiberglass or cellulose can be used in high humidity siuations safely. Choose rigid insulation wisely and consider the effect its characteristics will have on the performance of the your project overall product cost and the best way to get the bang for your buck. Rigid foam insulation packs a lot of r value into a thin package but not all rigid foam performs the same.
