Use: Prodex 48 Inch, 10 M, Fast Action, 72 Inch, 24 Inch, 16 Inch, White, Reflective Bubble Reflective or Foil Fiberglass Vinyl.
Cut three inch wide strips of insulation from your rolls. Tape (double sided tape) and glue (super metal sealant) the strips of insulation every two feet on roof and walls. The tape is designed for immediate adhesion. The glue will provide long-term adhesion. Glue and tape the insulation to the cut strips as shown in photo below. Tape insulation seams with reflective tape or use Prodex Fast Action or 10M to avoid seam tape.
A Sprinter Van insulation system requires a Radiant barrier, Vapor Barrier, and Reflective Insulation because of the unique nature of the metal. The sun's rays on the metal surface creates unbearable heat inside the container in the summer. Cold winter temperatures are exaggerated by the metal sheeting making it frigid inside. Warm temperature on a cool metal creates sweating (condensation). Prodex Total serves a true vapor barrier and condensation eliminator. It has a high R-value and it prevents radiant heat transfer (primary source of heat-flow). It's superior to fiberglass batt in metal cargo vans because it is unaffected by humidity or water -- It doesn't mildew or promote fungus growth and it keeps the van cool in the summer - It is also much easier and less expensive to install. It is superior to double bubble insulation in vans because the heat from the metal skin doesn't cause its polyethylene micro-bubbles to collapse. With a pressure of 6 PSI Prodex compresses just 6%. When the load is relieved it takes back its initial shape. The density of the foam is between 1.25 lb/ft (sq) - 1.87 lb/ft (sq). This gives the material real body.
