Insulation Panel Failure

The thin aluminum facing on polystyrene insulation panels in a mushroom-growing plant partially delaminated. The delaminization voids filled with water which condensed on the surfaces of the insulation panels due to the high humidity environment maintained in the plant. It was alleged that the water trapped in the delaminization voids became a source of nematodes which would subsequently leak out of the panels, contaminate the compost, and cause a drastic reduction in mushroom yield. APTECH inspected the panels and performed a heat transfer analysis of the compost tunnel and a modification of the original design of this tunnel.
