This new custom hillside home called for both types of spray foam. A.S.I.'s crew applied closed-cell foam against the roof deck between the beams and joists and in exterior walls, where its strength and moisture resistance count most, and used open-cell foam to fill other wall cavities and a ceiling grid around ductwork. Matching the foam to each assembly gives the house a tight, well-insulated envelope and a quieter, more comfortable interior.
