Buy Insulation for Metal & Steel Buildings Online

Metal & Steel Barn Insulation at InsulationStop.comYou choose to insulate a metal or steel building for several reasons. The main emphasis is to keep the inside temperature comfortable for both the heating and cooling seasons whether the building is designed for humans or livestock.

A correctly insulated metal or steel building slows down heat transfer and stops drafts in both hot and cold climates.

As these structures are excellent in their cost and ease of installation they are also prone to condensations issues. Insulation is the major factor in condensation control and there is no better insulation for your metal or steel building than reflective foil insulation.

Maintaining consistent indoor temperatures using foil insulation and correct ventilation will protect not only the building itself for years to come but also any equipment or agricultural products you choose to house or store inside.

The best insulation for metal and steel buildings is reflective foil because in one product it provides thermal insulation, a radiant barrier, and a vapor barrier to eliminate condensation. Foil insulation is made in either a foil/foil or foil/white configuration that provides an attractive finish and enhances the aesthetics of your building and improves the lighting. It is used for all aspects in the construction; under walls, under roof decking, under floors, and around ducts and pipes.

Foil insulation consists of two layers of foil or one layer of foil and one white layer (poly) with a layer of single or double bubbles at its core. Reflective foil insulation uses trapped air space as part of its design to slow the flow of convective heat, the same way fiberglass insulation works.

Heat gained through radiation is responsible for 65-85 percent of all the heat transferred through the walls and roof. Aluminum, the second most reflective material behind gold, reduces radiant heat transfer by as much as 97%. Because of this, foil insulation is extremely effective against radiant heat transfer because it reflects almost all of the invisible radiation striking the surface and emits very little heat that does conduct through it. The result is your building does not get as hot in the summer and keeps warm air in during the winter.

Perhaps the best reason to use reflective foil insulation in your metal or steel buildings is to help control condensation. Water vapor will condense inside a building whenever it contacts a surface that is cold enough. Through the heat transfer process of conduction, this air will lose heat to the cold surface. Condensation occurs when the air reaches its saturation point. (The cooling air lowers the dew point and relative humidity increases until the saturation point where condensation occurs.)

Moisture in metal and steel buildings is present for many reasons. Humans and especially animals give off considerable amounts of water through breathing and perspiring. Heating through the use of gas, oil, and propane also give off significant amounts of moisture through the combustion process. Exposed earth also gives off a tremendous amount of moisture because the soil is exposed to the air. Freshly poured concrete is another major source of large amounts of moisture. Correct insulation and ventilation is needed in all of these circumstances or moisture may become an issue.

Moisture and condensation can either be exposed or concealed. Exposed condensation is when you can see moisture appearing on the inside surfaces. This is generally present on windowpanes or purlins and results in dripping water. Installing reflective foil insulation reduces the cold surfaces where condensation is likely to occur. Providing correct ventilation to exchange the indoor moisture rich air with outdoor air will reduce the amount of condensation in your building. This is accomplished generally through the use of circulating fans. The addition of a vapor barrier under the floor will also greatly help to reduce this issue.

Concealed condensation is more difficult to control and can cause more damage than exposed condensation. This occurs when water vapor has passed through the insulation and condenses on the metal surfaces of the roof or exterior wall or inside the insulation. The best way to control this is during the construction of your building making sure to have proper roof ventilation and a tight vapor barrier.

Preventing concealed condensation is the most important component in the health of your metal or steel building. Using vapor barriers are critical. A vapor barrier will significantly reduce the movement of vapor transmission. Foil insulation has a perm rating of 0.05 which makes it an excellent vapor barrier. It's waterproof and when correctly installed can reduce or even eliminate condensation. It doubles as your wall and roofing insulation and vapor barrier all in one product. Because the material does not absorb moisture it will not mildew, rot, or promote fungus growth.

For these reasons, traditional fiberglass batt insulation is not recommended for metal or steel buildings. Instead of warm air rising and striking the metal walls and roof directly and causing condensation and dripping, the insulation with its design makes the air cool gradually. The warmer, moist indoor air will cool and reach its dew point either somewhere inside the insulation or when it reaches the roof or walls trapping the moisture. Any moisture increase severely decreases the R-value and effectiveness in fiberglass insulation because water is also an excellent conductor of heat. And even though the metal in a steel building is treated, water trapped in or between the insulation will over time cause rust and oxidation or mold and fungus growth. All these conditions will degrade the steel walls and shorten the service life of the building.

Reflective Insulation Compared to Other Insulation Types

 Reflective insulation has higher R-values than any other type of insulation per inch. 1/4" thick foil insulation has more insulation value than 6 inches of common fiberglass insulation.
 Aluminum foil insulation is the only type of insulation that reflects radiant heat. Traditional fiberglass insulation has no effect on the transfer of radiant heat. Estimates are that between 80% and 90% of radiant heat that strikes fiberglass insulation will pass right through it. Reflective aluminum, the main component in foil insulation is an excellent radiant heat barrier, which reflects up to 97% of radiant heat striking the material.
 Reflective foil insulation is the only type of insulation that can be used as a vapor barrier. All other insulation types require the addition of a separate vapor barrier to prevent moisture accumulation in the walls and ceilings that causes rot, mold, fungus, and dripping water.
 Reflective insulation will not compress or absorb moisture, all conditions that seriously degrade the performance of batt and blanket insulation systems.
