Open-cell spray foam insulation is an effective solution for architects and commercial builders to consider helping maximize air control and minimize related problems. In addition to energy efficiency, good quality open-cell spray foam also aids in moisture management.
When addressing moisture, open-cell spray foam is better suited for use against building materials could potentially be damaged by water build-up such as exterior wood sheathing. When applied against such materials, particularly in the hot/humid southern climates of the continental United States, insulation should allow for moisture diffusion to occur, just enough to let adjacent building materials breathe in order to prevent moisture entrapment.
Open-cell spray foam, such as Icynene’s LD-C-50, delivers this ‘breathability’ and allows building materials to dry, minimizing moisture build-up and related problems such as mold.
