Ag Barrier®

Radiant Barrier

Ag Barrier Product Main2


Many people in the agriculture business recognize that controlling the temperature in their warehouses, barns, and stables can be a growing problem. This is commonly known as the “black-globe effect” and combatting it can become increasingly expensive. Ag Barrier® is our product built to be a money-saving insulation alternative for the agriculture industry. This low cost, highly effective barrier is composed of aluminum and polyethylene to form a superior product unlike any other in the agriculture market.

For new construction, Ag Barrier® is designed to be an upgrade from Tri-Ply ceiling material. Unlike Tri-ply, Ag Barrier® blocks 95% of the sun’s radiant heat from entering your confinement area.

For retrofits, Ag Barrier® improves performance of other forms of insulation when combined with traditional insulation.

Ag Barrier® Poultry House Curtains are also available.

How can Ag Barrier® help me?

Studies show that with the elimination of the “black-globe effect” using reflective metallized film insulation (Ag Barrier®), many improvements are immediately apparent. In the dairy industry, an increase of as much as 10% in milk production has been noted. The study also reported that the only notable change made was the addition of reflective insulation. In a different study, a conception rate improvement of nearly 24% was observed. Broiler house feed conversions went from averages of 2.3 to 2.8 pounds of feed per pound of bird to 1.99 feed conversion. With the same amount of feed, birds were noted to gain more weight.

What is the “Black-Globe Effect”?

Whether outdoors or indoors, in temperatures exceeding 78° F animals absorb a tremendous amount of radiant energy from the sun. Although the animal may be confined to a building, the “black-globe effect” on the animal is the same as if it were 10 to 20° F higher than air temperature. Just like humans, animals in higher temperature environments don’t fare well. In addition to other problems, this makes weight gain harder to achieve and diminishes dairy production amounts.

Poultry House Curtain

Innovative Insulation Inc. recognizes poultry houses are unique environments that require a sturdy, durable, and substantial poultry curtain material. Ag Barrier® Poultry House Curtains provide zero mold/fungus growth. It has a special UV-inhibitor alongside an anti-corrosive coating. This protects it from UV degradation, and the corrosive environment found in poultry barns. AgBarrier® was specifically formulated with properties that provide a superior, long-lasting performance as a Poultry House Curtain.

Frequently Asked Questions

The “R” value depends on the number and size of the airspaces surrounding the Radiant Barrier and on the direction of the heat flow. Since Radiant Barrier is usually installed on top of existing mass insulation, its R-value is a moot point. It is Radiant Barrier’s ability to reflect heat that makes it such an energy saver.

Just like wrapping a baked potato in aluminum foil keeps a potato warm longer by holding the heat in, covering your attic insulation with Radiant Barrier holds heat in the house. Another analogy would be that Radiant Barrier in the winter works just like a space blanket, which, although very thin and lightweight, holds your body heat in. A thin space blanket can keep you warmer than several heavy blankets.

Just like a space suit, Radiant Barrier reflects the sun’s heat before it can warm up the insulation in your attic. When the insulation stays cooler, your house will stay cooler. It helps to understand how Radiant Barrier will work for you if you think of other things that work in much the same way. Astronauts’ space suits keep body heat and reflect the sun’s heat away. Thermos bottles keep hot things hot and cold things cold. They are almost perfect insulators. The tight seal and air space prohibit heat transfer by conduction and convection. The reflective surfaces inhibit radiation heat transfer. If the bottle starts out hot, it stays hot because very little heat is transferred to the cooler outside. If it starts out cold, it stays cold because very little heat is transferred from the warmer outside.

No. Radiant Barrier actually makes your present insulation more effective.
