What is fiberglass batt insulation?
Fiberglass batt insulation is one of the more popular types for roofing. It’s relatively inexpensive, and available in a wide variety of different R-values. In case you’re not familiar, R-value determines thermal resistance. The higher the R-value, the more insulating the material is. Variable R-value is key because different climates need different levels of insulation.
Can fiberglass batts be moved?
Some of the problems you see in fiberglass batts are present here, as well; it’s rigid, so it’s not easy to move around tight corners or awkward areas. Fortunately, as it’s an exterior insulation option, these problems usually don’t come into play, as the roofing will be placed directly over the insulation.
Is rigid foam board better than batt insulation?
Rigid Foam Board. Rigid foam board is more expensive than batt insulation, but for good reason because the R-values of foam board are much higher.
