It is a nonstructural insulation that can achieve a nominal R-value of R-3.5 to 4 per inch.¹ Additionally, open-cell foam is more porous and can absorb moisture, leading to mold problems and structural damage over time. Closed … WebMost closed-cell spray foam is now formed using hydrofluorocarbon (HFC) blowing agents that have high global warming potential, partially or completely offsetting the climate benefits of the energy savings they can offer. In the United States, HFCs are scheduled to be phased out by January, 2024. pot of gold toy
