Prodex for cold and hot

Prodex Total 4 ft x 50 ft Insulation combines the benefits of insulation with vapor and radiant barrier protection. That means you'll have a cool, dry structure in the summer and a warm, dry structure in the winter. It is used as a stand-alone or supplemental insulation. Used as pole barn insulation, metal building insulation, attic insulation, garage insulation, roof insulation, basement insulation, crawlspace insulation, radiant floor insulation, wall insulation, air duct insulation, under concrete and more. Prodex works well in hot and cold climates. Other benefits include sound deadening and easy installation. Reflective aluminum foil on each side of 5mm (13/64) closed-cell polyethylene foam center.

Compare Prodex 48 Inch to fiberglass, radiant barriers, cellulose, rigid board, rock wool, double bubble.

To improve performance, tape seams with reflective tape. Heat and cold will seek the least resistance and find it at the seams. Taping the seams also helps to prevent condensation.

Additional approvals and certifications:


  • Wall Insulation: Radiation accounts for 65-85 percent of all heat transfer through walls.
  • Air Duct Insulation: 10 to 30 percent of the energy used to heat and cool the air is lost to conduction through the duct surfaces. 
  • Attic Radiant Barrier: A new generation attic radiant barrier not only reduces air conditioning bills - It also reduces heating bills. 
  • Basements and Crawlspace Insulation: Due to their underground environment, basements and crawl spaces have different insulation requirements than the house above. 
  • Garage Insulation: Insulate the wall between the garage and the rest of the house. This will reduce heat, cold and noise from coming into your home. 
  • Metal Building Insulation: Ever wonder why it's so hot and wet inside a metal building in the summer and so cold and wet in winter? 
  • Pole Barn Insulation: The best insulation for a pole barns will keep the inside of the structure cool in summer, warm in winter and dry all the time.
  • Poultry House Insulation: A little known natural phenomenon called the "black-globe effect" has a pronounced stress factor relating to the cost efficiency (or inefficiency) of weight gain in meat producing animals and birds. 
  • Roof Insulation: Because heat rises, you'll have more winter heat loss through your walls.
