Closed-cell spray foam appears to be a robust solution for insulation and moisture management in a variety of applications. Its ability to serve as an effective barrier against air, vapor, and moisture intrusion is particularly valuable, especially in environments where maintaining structural integrity and energy efficiency are priorities. The higher R-value and compression strength make it a compelling choice for both interior and exterior use, providing enhanced thermal performance and durability. Overall, it seems like a versatile and efficient option for improving the performance and longevity of buildings.
