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.
This is a large Retro-Fit that we did on Islesboro, Maine. We sprayed the attic and sealed all of the mechanicals into the heated space. This should cut their heating bills drastically.

This Job proved to be very interesting because the owner of the building had a 50 sail boat directly in the middle of the spray area!!

Especially with a high valued items like this sail boat.
On this job we cathedralized the building envelope by spraying our open cell foam directly the the roof deck. This helps to expand the living space and reduce wasted space.

This picture shows the process of insulating an underground heat run with closed cell spray foam insulation. On a similar project we sprayed a trench that was 300 feet long. The degree change from one end of the heat run to the other was under one degree!
