Inquiry (采购产品): Urethane Foam Insulation for Exterior Ductwork We are providing engineering services for a large addition to DSM's facility in Greenville , NC. We have been asked to compare Foamglas with urethane for insulation of outdoor exposed ductwork. Based on your experience, please provide us with a budget cost for furnishing, fabricating,installing, and finishing the following: 1.5 inch thick urethane insulation on 56 LF 50" diameter round stainless steel duct, outdoors 1.5 inch thick urethane insulation on 60 LF 60" diameter round stainless steel duct, outdoors Also, I need thermal conductivity at 75 F mean temp and a suggested specification (if available) We will be applying a metal jacket to this insulation. Is a vapor barrier required? How does price of urethane compare to Foamglas (rigid cellular glass)? Are there significant advantages in fabrication and application of urethane over Foamglas? Any problem applying to stainless steel? I look forward to your reply and budget estimates.Please respond by e-mail or fax.
