The original application of the foam was for kits to retrofit or repair old industrial air conditioners. The properties of the foam made it possible to improve the efficiency of existing air conditioners within the constraints imposed by existing facilities. The industry that builds and sells these kits is concentrated entirely in Calopeia. The market is highly seasonal but otherwise very stable. There are no long-run market trends, either upward or downward. The size of orders is very random with an average size of 7 or 8. Orders also arrive randomly.
