EPS vs XPS: Why EPS is Better – Poly Molding LLC

When people search the web for “insulation companies near me”, they key in on those that provide materials that are elite in terms of moisture management. EPS has comparably rigid insulation that is closed cell with an elevated tolerance that ensures moisture is resisted. In fact, field studies show EPS absorbs less moisture than anticipated.

Merely one-half of a percent is absorbed by EPS in a 15-year span, meaning it really is the best insulation for attic and also the best insulation for walls. Furthermore, when moisture moves into tiny cavities, EPS has a superior ability to expel that moisture.

Add in the fact that EPS has drying potential and XPS does not have such potential and there is even more reason to choose EPS. Drying potential is particularly important in the context of thermal insulation as it helps ensure the optimal thermal resistance, also known as R-value, is maintained amidst extensive exposure to moisture and other threats.
