Many don’t like spray foam but this is a missed opportunity for energy efficiency.
During a recent inspection of a home in New Orleans, a concerning issue came to light – an improperly applied closed-cell spray foam insulation. The photograph showcased a mere quarter-inch thickness of insulation, which falls far short of the recommended 1.5 inches necessary for an effective thermal and vapor barrier.
In the warm and humid climate of New Orleans, proper insulation is crucial for maintaining energy efficiency and a comfortable indoor environment. The thin layer of insulation observed in this home is insufficient to provide the desired level of protection.
In summary, the quarter-inch thick closed-cell spray foam insulation seen in the image is inadequate for maintaining thermal comfort and preventing moisture-related problems. See this HGTV site for more information.
