A large twin-sheet part, approximately 6' x 6', used to insulate an ice making machine used to generate air-conditioning coolant during peak usage hours with ice made from electricity in off-peak hours. The part is comprised of two sheets of different gauges and colors of Solvay's E3000 TPO elastomer, a plastic with excellent weatherability and expansion/contraction properties. The part is twin-sheet formed and then filled with a 2-part urethane 2# density foam for insulating properties. Created for: Ice Energy
