Xps Vs. Polyiso Insulation: Properties And Applications
XPS polystyrene foam and polyiso are two types of rigid foam insulation commonly used in construction. XPS is made from extruded polystyrene and has a denser, closed-cell structure, providing better moisture resistance and compressive strength. Polyiso, also known as PIR or PUR, is made from polyisocyanurate and has a more open-cell structure, offering higher thermal…
