WHY EPS VS XPS? GET THE FACTS!
Facts about moisture resistance and R-value retention of EPS1 A 30 month field research study conducted by the National Research Council of Canada/Institute for Research in Construction (NRC/IRC) jointly with the Expanded Polystyrene Association of Canada (EPAC) on EPS samples concluded the following:
1) The moisture content of EPS insulation directly exposed to high moisture content soil conditions was found to be less than 0.5% by volume on average at the end of the exposure.
2) In-situ thermal performance of the EPS insulation monitored during the exposure period remained constant, i.e., there was no loss in thermal resistance.
3) Laboratory test results from samples removed after the exposure confirmed thermal performance and durability, i.e., there was no change in material properties.
4) “A second part of the research project included development of a durability test protocol that subjected test material to extreme thermal gradient and environmental cycling, including freeze-thaw cycling.Testing performed by NRC on samples of the same material that was subjected to the 30-month field exposure confirmed that all types of EPS insulation retained their specified material properties even after being subjected to the durability test protocol”

Facts about the effect of freeze-thaw on properties of EPS2
An independent third party testing was conducted on EPS in accordance with ASTM C1512-07, a standard which assesses the effect of freeze-thaw cycling on thermal performance and also determines the moisture absorption of insulation when exposed to the rigors of environmental cycling. The tests concluded the following: “These independent tests confirm the freeze-thaw and moisture resistance properties of EPS insulation. Test results confirm no loss in R-value or change in compressive strength for EPS. Additionally, the results clearly demonstrate that EPS insulation does not absorb excessive amounts of moisture”.
Facts about In-situ R-value retention over the long term of EPS and XPS3
Independent testing conducted after a 15 year period installation of EPS and XPS samples concluded the following:
1) EPS Type I out performs XPS Type X in both R-value retention and decreased water absorption.
2) Whereas the in-service R-value of the XPS insulation is reduced by half, expanded polystyrene still delivers 94% of its specified Rvalue of 3.6 per inch after 15 years.
