Closed Cell and Open Cell Hybrid in Belfast, Maine
On this job we decided to do a hybrid system. We sprayed our open cell foam to the attic floor. Then we sprayed the walls with closed cell. We did this because this is a metal building. The closed cell offers the rigidity and low vapor permeable material needed for metal buildings. However we were able to spray open cell to the attic floor which provided our customer with decent savings on the project because our open cell is less expensive.
