Which is better EPS or XPS?
XPS, at about R-5 per 25 mm, has only a slightly better thermal performance than EPS. However, EPS with the same level of density is less expensive. XPS is usually avoided in areas where materials with less density are needed or where the material, which is not produced below a certain density, is not applicable.
