As the spray foams are designed to be in contact with an air barrier, you do not have to worry about the proper alignment. Despite the best results, there are few pitfalls of this method that you cannot ignore.

Spray Foams Are Thin

Whether you choose closed cell foam or open cell foam, they both offer a thin layer. As the R-value of closed cell is higher per inch, it is generally sprayed 2 inches in walls and 3 inches in rooflines so that your building insulation can meet the energy codes.
