You can make the most of your investment with spray foam insulation. New homes are the best suited for spray foam because greater access to wall spaces allows the foam to expand effectively into all difficult-to-access areas.
Moreover, you will be reducing your future home maintenance costs by mitigating ice dams, preventing mold build-ups caused by other insulation types and saving yourself the retrofit headache when the lifespan of other insulations nears its end. Spray foam lasts indefinitely, so long as it is cared for properly.
