Open-cell foam is a very light material that is designed to break or pop as the foam expands but before it sets, allowing pieces to be removed. Open cell foam is low density and can fill larger areas with less material, and it has a R-value of 3.5-4 per inch.
On a cost-per-R basis, open-cell is the more economical spray foam choice. However, it is not as effective as closed-cell spray foam. Open-cell is a more environmentally friendly option as well, which is a benefit for homeowners concerned about their environmental impact.
