A metal building insulation system requires a Vapor Barrier, Radiant barrier and Reflective Insulation because of the unique nature of metal sheeting. The sun's rays on the metal surface creates unbearable heat inside the building in the summer. Cold winter temperatures are exaggerated by the metal roof and wall sheeting making it frigid inside. Warm temperature on a cool metal roof or wall creates sweating (condensation). Prodex serves a true vapor barrier and condensation eliminator. It has a high R-value: R 16 and it prevents radiant heat transfer (primary source of heat-flow). Comparing Metal Building Insulation : Prodex Reviews

 
Metal building roof and wall insulation installation over purlins

Roof/Wall (New Install) Over Purlins: Use Prodex 48 Inch, Fast Action, 72 Inch, Prodex Rustic (Light or Dark), Reflective Bubble Reflective or Foil Fiberglass Vinyl.

  1. Apply double sided tape on the top of purlins (helps keep the insulation from blowing in the wind).
  2. Roll insulation perpendicular to and over the purlins. Allow insulation to sag 1 to 3 inches. If using two layers of insulation, push inside layer of insulation slightly more so a 1-3 inch air-gag exists between the layers. 
  3. Tape seams with reflective tape or use Prodex Fast Action to avoid seam tape.
  4. Attach your sheeting

Metal building insulation installation roof and wall over and under purlin 

Roof/Wall (New Install) Two layer Prodex - Over and Under Purlin: Use Prodex 48 Inch, Fast ActionProdex Rustic (Light or Dark) or 72 Inch.

  1. Apply double sided tape on the top of the purlins (helps keep the insulation from blowing in the wind).
  2. Roll insulation perpendicular to and over the purlins. Allow insulation to sag 1 to 3 inches.
  3. Tape seams with reflective tape or use Prodex Fast Action to avoid seam tape.
  4. Attach your sheeting
  5. Glue (super metal sealant) 2nd layer of Prodex to underside of purlins. Run the insulation perpendicular the purlins - That way a 48 Inch wide roll will work regardless of the width between your purlins.

Existing Buildings: Roof/Wall Install (Interior/Retrofit) with or without Existing Insulation: Use Prodex 48 Inch, Fast Action, 72 Inch, Prodex Rustic (Light or Dark), Reflective Bubble Reflective or Foil Fiberglass Vinyl.

Glue (super metal sealant) and tape (double sided tape) the insulation to underside of purlins. Run the tape and glue adjacent to each other. The tape serves as short-term hold and the glue serves as long-term hold.

Run the insulation perpendicular the purlins - That way a 48 Inch wide roll will work regardless of the width between your purlins. Use double sided tape to hold the insulation while the fast drying glue sets. As a precautionary measure, use a self-tapping screw every four feet to reinforce the attachment.
