The first two pictures are of spray foam we installed to a Controlled Atmosphere (CA) Room Mezzanine Wall. The existing design of the wall required only fiberglass insulation, after the first year the new CA facility was in operation the mezzanine area started to experience severe issues of condensation which led to mold. K-5 Contracting installed 2” inches of 2 lb. wall foam and protected the foam with ½” inch of white cementious thermal barrier. Condensation problem solved. For clarification the spray foam and grey fireproofing on the ceiling was done by a different contractor.
The remaining five pictures are various photos of work in a typical CA Room for apple storage.
