As a strategic move to strengthen our efforts and vastly improve the Ultra R product line, we have made the difficult decision to no longer provide our custom Marine freezer panels. Glacier Bay would like to extend our sincere gratitude for the many years of support we have received from personal yacht and boat owners who have enjoyed the unsurpassed value of this product line. For those of you who are in process or thinking about placing an order, March 31st , 2011 will be the last day we can accept an order of this type. Due to the overwhelming demand for Ultra R insulation in a rising global market we must continue focusing resources on our unique R&D capabilities and commercialization efforts.
