These is What Rigid Foam Insulation is Made of
These is What Rigid Foam Insulation is Made of The foam insulations are good substitute to the insulators like fiberglass or cellulose. The foam insulators are used where the high R-values are desired. Even though the cost is greater than that of the batt insulations or fiberglass rigid foam insulations are preferred for high performance. The R-value (per inch of thickness) of foam insulations range from R-4 to R-8. This range of R-values is 2-3 times greater than the r-values of other materials. The foam insulations are made up of three materials which includes the extruded expanded polystyrene (XEPS), molded… Read more about These is What Rigid Foam Insulation is Made of →
