...Polyisocyanurate (PIR), Extruded Polystyrene (XPS), Expanded Polystyrene (EPS) or Styrofoam? When building or renovating a high-performance building envelope there are really three main kinds of rigid foam panels you are going to have to choose from - Polyisocyanurate known as Polyiso (PIR), Extruded Polystyrene (XPS...

...polyisocyanurate and stone wool ], measurements of R-value per inch were made over a range of different temperatures more characteristic of in-service temperatures. As shown in Figure 1 below, these measurements found that the R value of both insulation types change with temperature, with the polyisocyanurate [polyiso]...
