Rigid Foam vs. Fiberglass Insulation Comparison Guide


Insulating properties of various building materials are measured by R-value—a measurement of the thermal resistance of the material. Higher R-values indicate better insulating values.


With both rigid foam and fiberglass, the R-values are mostly determined by the thickness of the insulating material. Rigid foam insulation packs in more R-value per cubic inch than fiberglass insulation does. If conserving energy is your main goal and there are no other influencing factors such as moisture, rigid foam may be your first choice. #insulation #atticinsulation #adlamfilms
