How To Insulate A Metal Building: Master Guide (2024)

• Print Friendly Version Print

The most popular metal building insulation is Prodex Total 10M. The following are excellent 5M choices: 48 INCH, FAST ACTION, 62 INCH FAST ACTION, 72 INCH, WHITE, RUSTIC, 24 INCH, 16 INCH.

Other options include: Reflective Bubble Reflective and Foil Fiberglass Vinyl.

Please select an install method to determine which items below that you will need.

• Reflective tape
• Double sided tape
• A utility knife
• Super metal sealant (someretrofit applications)
• A screw gun (someretrofit applications)
• Metal Screws(someretrofit applications)
• Metal Pins and Caps (someretrofit applications)

Double sided tape keeps the insulation from blowing during the installment process and helps attach insulation to the surface.

Super Metal Sealant is used to attach insulation and metal pins to virtually any surface including steel, aluminum, painted metals, galvalume, wood, fiberglass, fiber-reinforced plastic and concrete.

Pins and Caps are used to attach insulation to virtually any surface including steel, aluminum, painted metals, galvalume, wood, fiberglass, fiber-reinforced plastic and concrete.

Heat Gun is used to seal the seams of 10M Prodex Total. The recommended heat setting is between 200 to 350°C. Start with the lowest temperature to avoid damage of the material. You can also use reflective tape to seal the seams of 10M. Better install - New thermal weld systemVideo

Install Options:

1. New Install Roof And Wall - Installing Over Framing

1. Apply double-sided tape on the top of the purlins to prevent insulation from blowing in the wind.
2. Roll the insulation perpendicular to and over the purlins.
3. Allow the insulation to sag at least two inches (creating air-gap).
4. Use reflective tape to seal the seams. Fast Action and10M don't require seam tape.
5. Attach sheeting.

Insulating an existing metal building is known as retrofitting and it can refer to structures with or without prior insulation layers.

D. Attach Insulation with double sided tape and glue:

Any metal building that uses fiberglass insulation rather than Prodex Total will have moisture issues (typically hidden behind facing), Loss of R-value (consequence of the moisture) and heat gain.

A metal building insulation system requires a reflective insulation, radiant barrier and vapor barrier. The metal skin causes sweating (condensation), unbearable heat in summer and frigid temperatures in winter. Prodex serves a true vapor barrier and condensation eliminator. It has a high R-value and also prevents radiant heat transfer.

Prodex Total is superior to fiberglass in metal buildings and pole barns because its R value is unaffected by humidity or water -- It doesn't mildew, promote fungus growth or the nesting of rodents, bugs and birds. It is also much easier and less expensive to install. Unlike expensive spray foam insulation, Prodex Total prevents radiant heat transfer. It is superior bubble insulation in metal buildings because the heat of the metal skin doesn't cause its polyethylene micro-bubbles to collapse.

Ever wonder why it's so hot and wet inside a metal building in the summer and so cold and wet in winter? The metal skin magnifies the heat of the summer and frigid temperatures of the winter. Metal is a very good conductor of heat and cold. In hot weather, metal framing and sheeting rapidly transfers the sun's heat into a building, and in cold weather it rapidly transfers the cold in. When a cold surface comes in contact with warm air it creates moisture on the surface (cold beer can outside in summer). Prodex eliminates the moisture (condensation) on the metal sheeting, it prevents the heat from entering your building in summer and leaving your building in winter!

You'll have a cool, dry structure in summer and a warm, dry structure in winter. It is used as a stand-alone or supplemental insulation. It is ICC-ES Recognized - It reflects 97% of radiant heat (the primary source of heat flow). Prodex works well in HOT and COLD climates. Other benefits of Prodex include sound deadening and sealing around nails.
