WebClosed cell foam insulation has a higher R-value than open cell foam insulation, which means that it provides better insulation and can help reduce energy costs. However, closed cell foam insulation is also more expensive than open cell foam insulation, so it may not be the best choice for all budgets. 3. Moisture Resistance WebAll closed-cell polyurethane foam insulation made today is produced with a non-HCFC (hydrochlorofluorocarbon) gas as the foaming agent. Low-density, open-cell polyurethane foams use air as the blowing agent and have an R-value that doesn't change over time. These foams are similar to conventional polyurethane foams but are more flexible. pine mountain state park lodge kentucky
