The most common types of foil faced insulation include foil faced fiberglass, foil bubble wrap insulation, Prodex and foil rigid insulation panels.
When you choose insulation for your project, you should always pay attention to its R-value.
An R-value is an index that measures the ability of the insulation material to block heat transfer. The higher the R-value, the more effective insulation is against heat resistance.
Lets look at each type of foil faced insulation, plus their characteristics and what theyre typically used for.
At Insulation4less, our foil fiberglass vinyl insulation is made of a ¼-inch fiberglass core, one layer of 99% pure aluminum and one layer of durable white scrim-reinforced facing material.
Foil fiberglass vinyl insulation provides excellent thermal performance.
Foil fiberglass vinyl insulation can be used for both commercial and residential applications, whether you are retrofitting or insulating new construction.
When used in retrofitting, compact roll sizes make the installation process fast and easy. In new applications, splices are quickly and easily made and this eliminates the aggravation of ordering custom-cut roll lengths.
Unlike many other types of insulation, foil fiberglass vinyl insulation has an encapsulated fiber core that prevents skin irritation when you come in contact with it.
When you apply foil fiberglass vinyl in commercial structures, it can reduce energy bills and prevent the outside weather from affecting your indoor environment. Foil fiberglass vinyl is the perfect insulation choice in many Southern states specifically, where 3 or 4 faced fiberglass insulation is typically used.
Foil faced insulation rolls are compact, thin and lightweight, which makes the installation process quick and easy. It provides a white finish and a smooth, clean, interior appearance.
At Insulation4Less, our foil fiberglass vinyl insulation comes in two sizes. The 4 ft x 125 ft roll is enough to insulate an area of 500 sq ft, while the 6 ft x 125 ft roll covers 750 sq ft.
Foil bubble wrap insulation consists of either a single layer or double layers of encapsulated air bubbles pressed in between sheets of foil.
Foil bubble insulation comes in two different types. The external layers can include two surfaces of metalized, low-emissivity surfaces (bubble reflective insulation) or one metalized low-emitting surface and one layer of white polyethylene (bubble white poly).

Bubble reflective insulation serves as a vapor barrier and provides a thermal break. The two metalized surfaces reflect up to 96% of radiant energy.
Bubble white poly insulation acts as a vapor retarder and provides a thermal break. We recommend this type especially in under concrete applications because it blocks moisture, toxic gases and pests from entering your home through the soil.
At Insulation4Less, Prodex is our most sought-after type of insulation, and for good reason!
It contains two foil surfaces. One is a high-thermal reflectance one while the other represents a low emittance reinforced reflective foil. In between there is a closed-cell polyethylene foam center.
Thanks to its composition, Prodex is extremely durable and stable. It has a rippled surface that facilitates airflow and serves as an efficient vapor barrier.
Prodex prevents 97% of radiant heat transfer and is resistant to fire and compression.
It is light, easy to work with and seals well around nails, which makes it a preferred option for both commercial and residential applications.
The foil surface of Prodex helps prevent rodents, bugs and birds from entering your home or structure and nesting. Its also resistant to mold and mildew, which helps ensure a healthy environment inside your home.
1. Prevents Condensation
Do you know what occurs when warm air contacts a cold surface? The same phenomenon occurs when you take a soda bottle out of the refrigerator on a summer day. Condensation. Needless to say, when there is a temperature difference between the outside of a steel building and the inside, condensation will occur on the steel sheeting. Simply stated, condensation means moisture (water vapor in the air) on the metal skin. Condensation is the #1 cause of damage to steel buildings and their contents!
It is imperative that a steel building stay weathertight. Once moisture has entered a building, a host of immediate and long terms problems can occur, such as mold, mildew, fungus growth, white rust, and oxidation. Most of these results can also cause adverse health effects says John Barber, president of Factory Steel Overstock.
The primary purpose of insulation is to keep the building cool or warm when needed. Condensation eventually will dampen fiberglass insulation and directly compromise its integrity by lessening its R-vale. Therefore, in most cases, we would recommend Reflective insulation over fiberglass when an R-value of 22 or less is sufficient or the location has a humid climate.
All metal building insulation system requires some form of reflective insulation, radiant barrier, and vapor barrier. Unmistakably, you need a true vapor barrier and condensation eliminator! We believe our reflective insulation is superior to fiberglass batt in steel buildings or pole barns because its R-value is unaffected by humidity or water. In a nutshell, this means it doesnt mildew or promote fungus growth. The reason we do not promote spray foam insulation is that it is very expensive and not remotely as effective as reflective insulation regarding radiant heat transfer. The reason our reflective insulation is better than double bubble insulation is that the heat of the metal sheeting wont cause our polyethylene micro-bubbles to collapse. There is a reflective aluminum foil on each side of our 5mm and 10 mm closed-cell polyethylene foam center of our R-17 and R-22 insulation types.
