Reflective Resources Guide

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!

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.

Difference 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.

The Bubble and FSO’S insulations are both advantageous in giving R-value, a radiant and vapor barrier. Beyond this point, they have little in common. You see, FSO’s high R-Value 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 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!

Regarding 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!

  • Polyethylene backing
  • Close -cell polyethylene foam center
  • Reflective reinforce foil

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.

Installation Procedure

Recommended Purchase – Double Sided Tape

  • Comes in rolls of 4
  • Dimensions – 1 1/2″ x 60′
  • Serves 2000 sq. ft.

3 Simple steps to install:

  1. 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.
  2. 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 accordingly.
  3. Attach your sheeting.

Why do I need insulation?

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).

Reflective Insulation Protects Against 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 doesn’t 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 won’t 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. 

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!
