Comparing Prodex Total Insulation to Bubble, Spray and Fiberglass
Fiberglass Insulation Loses R value
Once fiberglass insulation gets wet (and it will get wet, due to condensation) it will lose R-value! Water trapped between fiberglass insulation and the exterior of a building will also cause mold, fungus growth, rust and oxidation - Conditions that will degrade the metal and shorten the service of the structure. In addition, fiberglass insulation does not prevent radiant heat transfer (the primary source of heat-flow in and outside your building).
Take a look at the white vinyl facing the next time you're in a metal building - It will be either sagging, or sagging and flaking. This is due to the added weight of water. Behind the white vinyl is a wet, mold filled blanket that will eventually cause the white vinyl to crack and fall off. At some point, when you're exposed to the toxic fibers, you'll be forced to remove the insulation - Hopefully before it does too much damage to the metal framing. If you insist on using fiberglass, use it in conjunction with Prodex Total, so the Prodex can keep the moisture out of the fiberglass.
Spray Foam Insulation Won't Stop Radiant Heat Transfer
In addition to being very expensive, spray foam insulation won't prevent radiant heat transfer (the primary source of heat-flow in and out of your metal building). Without a radiant barrier, when your roof gets hot it radiates solar-generated heat down. This often results in it being hotter in your building or house than out. It's also suggested you supplement open cell foam with a vapor barrier. Why not get the vapor barrier all in one product?
More benefits of Prodex Total Insulation
Protect Content From Vapor
Prodex is a class 1 vapor barrier. A vapor barrier (moisture barrier) refers to any material that prevents moisture from passing through the walls or roof of a building. This material can be plastic or better yet, Prodex Total Insulation - 13/64 inch, 5mm closed cell polyethylene foam covered on both sides with .0012-inch (00.03mm) aluminum foil facing. Prodex Total Insulation (Vapor Barrier, Class 1. perm<0.1 ).
Prodex Insulation Prevents Rodents, Bugs and Birds from Nesting
Unlike fiberglass insulation, Prodex does not provide for the nesting of rodents, bugs and birds. Rodents, bugs and birds aren't able to digest the aluminum.
It's a lot easier and less expensive to install a 5mm roll of Prodex than a bulky 6 inch roll of fiberglass. Pinching 6 inches fiberglass between the framing and sheeting is not easy. Prodex Total can be installed before or after your metal sheeting. For fastest and easiest installation, install before applying your sheeting. metal building installation methods
Prodex Total Deadens Sound of Rain and Hail
Metal skin on a building can exaggerate the sound of rain and hail. Prodex has an excellent 19db sound deadening.
Increased Lighting Efficiency
Prodex provides a bright, attractive finish to your building. It reflects the light, making it easier to light the building interior.

To meet the unique insulation requirements of a metal building you need a total insulation system - Prodex Total Insulation = Insulation + Radiant barrier + Vapor barrier.
Insulation Roll Sizes - metal buildings
48 Inch (4 ft. x 175 ft., 700 sq. ft.)
72 Inch (6 ft. x 100 ft., 600 sq. ft.)
Fast Action (4 ft. x 175 ft., 700 sq. ft.). Fast Action is identical to 48 Inch with the exception of having adhesive running 175 ft. on one side of roll. The adhesive is not for attaching the insulation to the surface - It is for sealing the seams. No need for seam tape.
24 Inch (Two rolls of 2 ft. x 175 ft., 700 sq. ft.)
16 Inch (Three rolls of 16 in. x 175 ft., 700 sq. ft.)
13/64 inch (approx. 3/16") - 5mm closed cell polyethylene foam covered on both sides with .0012 inch (0.03mm) aluminum foil facing.
Want White Facing?
Foil Fiberglass Vinyl (Not A Prodex Product) R 10.7. The performance level of this product is slightly less than Prodex Total primarily because it only has one reflective surface.
4 ft. x 125 ft. and 6 ft. x 125.
Ideal for commercial or residential applications where white facing is preferred. Radiant barrier composed of 1/4 inch fiberglass core bonded to one layer of aluminum foil facing and one layer of durable white scrim-reinforced facing material. Fiberglass is encapsulated.
