Open-cell foam is porous, allowing water vapor and liquid water to penetrate the insulation. It typically has R-values of 3 to 4 per inch (RSI-0.53 to RSI-0.70 per inch). Open-cell foam is soft when cured, with little structural strength. It requires trimming after installation, and disposal of the waste material.
