Polyiso Shortage - Now What
Engineered EPS (Expanded Polystyrene) insulation is a great alternative to Polyiso. Technically, EPS has many advantages over Polyiso. Some contractors may say that Polyiso has a higher R-value, while that is correct when we are talking published R-value but, Service R-value is a different matter. Long-Term Thermal Performance (LTTP) has show that Polyiso's R-value goes down dramatically as it ages. Further studies have shown that Polyiso's R-value decreases when the temperatures go down - this is when R-value is needed the most. EPS has a stable R-value and only changes by increasing it effectiveness when it gets cold. This is just one of many reasons that EPS is superior to polyiso.
