Pertinent information on the most popular THREE reflective insulation types.
Finally, a High R-Value Reflective Insulation that is an ALL-IN-ONE solution for HEAT, COLD, CONDENSATION, AND MORE!
8 Reasons Why to Buy our High R-Value Reflective Insulation
2. Stops Mold and Mildew
We’ve all seen some form of discoloration on walls. This is a reflection of a type of mold or mildew. These are the primarily types of fungi that can grow in your building if you don’t have the proper insulation:
- Aspergillus niger
- Aspergillus avus
- Aspergillus versicolor
- Penicillium funiculosum
- Chaetomium globosum

3. Vapor Barrier
Our insulation is the best vapor barrier in the industry because of its closed-cell polyethylene foam and reflective reinforced foil facing. Another advantage is our reflective insulation has no leaks because it seals around nails and screws.
4. Installation is Quick and Easy
- Apply our double-sided tape on the top of the purlins. Initially applying the tape will help secure insulation – and not allow it to blow in the wind.
- Roll insulation perpendicular to and over the purlins. It would be wise to let the insulation sag 1 to 3 inches. Then seal at the seam according.
- Attach your sheeting.


5. Rodents, Bugs, and Birds can’t Nest in it
I am sorry to say that fiberglass insulation allows rodents, bugs, and birds to nest. However these creatures can’t digest foil.
6. Reduces Sounds of Rain and Hail
Have you ever been in a steel building when it rained or hailed? You would definitely remember because the metal sheeting exaggerates the sounds. Our insulation deafens the sound.
7. Air Barrier
The moisture that is carried in the air can impact the temperature and integrity of a building. The airflow within a steel building determines the spread of toxic smoke and gasses. Garages and conditioned spaces are separated by air barriers. An additional safety feature is the air barrier also acts as a gas barrier.

8. Stops Heat Transfer
An insulation R-value is the measurement of a material’s ability to stop heat and cold transfer. No matter what a metal building’s usage, insulating it will be of value. Because of the unique nature of a steel building, it requires a vapor barrier and a radiant barrier.
- The summer heat (sun’s rays) on a steel surface will create extreme heat temperatures inside the building.
- In addition, the cold winter temperatures are exaggerated by the metal roof and wall sheeting making it frigid inside. Warm temperatures coming in contact with cool metal roofs or walls create sweating (condensation).


Fiberglass Insulation will loose some of its R-value as well as crack
Eventually, fiberglass insulation will get wet and once it does it will lose its R-Value. The trapped water will also cause mold, rust, and oxidation. Not to mention, fiberglass insulation isn’t a radiant barrier. However, our High R-Value Reflective insulation is not affected by humidity. Remember there will always be some humidity and insulation must work in these conditions. Take a look at the picture on the right, eventually, this is the outcome of Fiberglas Insulation. Not to mention, it is quite common to notice some sagging and flaking a few years after installation.

Why you shouldn’t use spray foam insulation
- It is too expensive
- It doesn’t protect your steel building from radiant heat transfer.
- It is labor extensive, so a professional is required for installation
- A great deal of spray foam can release toxic fumes when it burns

The Difference Between Reflective Insulation Types
There are four main reflective insulation products: Foil, Single Bubble, Double Bubble, and Factory Steel Overstock High R-Value (15.3, 17, and 22 when installed with an air gap) Reflective Insulation.




Radiant Layered Insulation
Reflective Bubble Insulation
Bubble insulation will offer some R-Value, a radiant and vapor barrier. Beyond this point, they have little in common with our High R-Value Insulation. You see, FSO’s insulation of polyethylene foam center keeps its shape when expose to numerous forces. This is very important! Under pressure, if insulation collapses, it loses its capacity to be an effective radiant and vapor barrier. With a 6-psi pressure, FSO’s high R-Value insulation only collapses 6%. Keep in mind, when the pressure is relieved, it fully forms back to its initial shape! This is not the case with Single or Dubble Bubble insulation.
Single or Dubble Bubble Insulation
This insulation is composed of air bubbles sandwiched between metal surfaces. Dubble bubbles simply mean a second layer of bubbles; however, we have found there isn’t much difference in performance between the two. Once a bubble is punctured it naturally loses some of its shape as well as radiant and vapor protection. Remember, all bubbles can pop!
Foil Insulation
Do you think that a simple piece of foil is going to offer much protection? I could elaborate, but common sense is all that is needed here!
What sets Factory Steel Overstock’s High R-Value Reflective Insulation apart is that it is LAYERED
R-Values 17 & 22

The creases in the foil allow for additional air flow. Making it the highest reflective R-Value insulation in the industry!
An insulation R-value is the measurement of a material’s ability to stop heat and cold transfer. No matter what a metal building’s usage, insulating it will be of value. Because of the unique nature of a steel building, it requires a vapor barrier and radiant barrier.
- The summer heat (sun’s rays) on a steel surface will create extreme heat temperatures inside the building.
- In addition, the cold winter temperatures are exaggerated by the metal roof and wall sheeting making it frigid inside. Warm temperatures coming in contact with cool metal roofs or walls create sweating (condensation); therefore, insulation is an imperative.
All insulation types have their niche. Factory Steel Overstock offers the two most popular insulations for Metal Buildings and Pole Barns -Fiberglass and Reflective Insulation. However, 75% of customers choose the Reflective insulation because of the EASE OF INSTALLATION, PRICE SAVINGS, AND High R- VALUES. The R-Values have been independently tested by ICC-EC.

The #1 Selling Insulation for Steel Buildings and Pole Barns
Over a million orders of this high R-Value Reflective Insulation have been sold. This totals more than 5 million square feet of insulation!
Many in the building industry would say the most popular insulation solution for decades, whether residential, commercial, industrial, or agricultural facilities, was fiberglass insulation.
Well, this one-size-fits-all application has quickly changed! There is a quickly growing realization that the best way to slow down conductive or convective heat transfer, one needs to look to other means than fiberglass. Based on independent government studies, it is REFLECTIVE insulation that is best suited for slowing down radiant heat as well as condensation. Radiant heat can account for as much as 93% of heat transfer. Therefore, in most cases, it makes sense to use a radiant barrier instead of foam or fiberglass. Keep in mind, our reflective insulation types are not affected by humidity. This is a very important point! If there is humidity outside, there will be humidity inside your building. Your insulation must work efficiently in these conditions.
Needless to say, every type of insulation has its justified building niche. That is why Factory Steel Overstock offers the public the two most popular insulation types: Fiberglass batt and Reflective insulation. But if you primarily want to reduce radiant heat transfer, and condensation as well as save money, reflective insulation is the way to go! Our reflective is a superior and complete vapor and radiant barrier! The reflective insulation product we offer reflects the highest amount of radiant energy flow (97%) that strikes it. It reflects the heat inside the metal building in the winter and reflects the sun’s heat outward during the summer months. All of this means less cost of your heating bill, as well as lower air conditioning expenses.

It is twice as thick as regular reflective insulation (10 mm) closed cell polyethylene foam covered on both sides with .00012 inch (0.03mm) aluminum foil facing. Its advantage is its high R-value, yet it is light and very easy to install.
Our High R-Value 22 has cuts at the edge to overlap the rolls. Overlap the rolls. Use a hot air gun to cause a welding process to occur. Simply add pressure and you will create an impermeable overlapped seal between the rolls.
Summation

Temperatures can be unbearably hot and humid in the summer as well as frigid cold in winter within a steel building. Why? Well, the metal skin itself magnifies the outside heat and cold because it is the perfect conductor of it. Again, when there are temperature fluctuations from outside to inside, a steel building will sweat (condensation). So, keep your metal building perfectly cool and dry in the summer as well as warm in the winter. Best of all, do it with price savings!
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.
