Exterior insulation is one of the best investments you can make if you're building in a colder climate. Apart from providing thermal comfort and energy efficiency, rigid exterior insulation significantly improves the walls' durability by preventing condensation that can lead to mold and rot problems and keeping the framing closer to interior conditions. Using rigid mineral wool, such as Rockwool Comfortboard, on the exterior will also allow the wall assembly to dry to the exterior unrestricted while providing resistance against wildfires as well as deterring pests like ants and termites.
