Which foam type is better – Murus Polyurethane foam or Murus EPS foam?
Neither foam is necesarily better than the other; rather, each foam type has unique properties and may offer advantages in certain instances. The primary difference between the two is the density of the foam. EPS foam density is a nominal 1 pound per cubic foot, while Polyurethane density is nominally 2.2 pounds per cubic foot. While Polyurethane SIPs provide a higher R-value per inch of thickness, EPS SIPs can be less expensive than Polyurethane SIPs, making them an affordable alternative to Polyurethane for the budget-conscious.
