What is a metal Barndominium and How To Insulate It (2024)

• Print Friendly Version Print

Barndominiums are an ideal combination of living quarters and recreational spaces, all housed in a low-maintenance, energy-efficient metal structure. Popular in rural areas, on ranches, and favored by individuals wishing to create more versatile spaces, these low-cost metal buildings may be configured in a way that includes a home with a workshop, huge garage, barn, horse stalls, airplane hangar, and other features.

The phrase "barndominium" is a combination of the terms "barn" and "condominium," and it refers to constructions that are exactly what they sound like: steel buildings with living quarters. While these structures may be completely customized to meet your specific needs, the majority of them have a living space and an associated garage. Most barndominiums have many rooms, bathrooms, a full kitchen, and a living area, as well as adjacent areas for garages, stores, and so on. Now, what makes a metal building a home, aside from the living quarters, is metal building insulation. Insulation can make or break the comfort of your living space and your whole barndominium experience.

Other modern amenities that make these living quarters desirable include plumbing, high-quality concrete floors, foam insulation, and much more. Their adaptability and ability to be modified to meet your vision, while staying a more affordable choice than standard dwelling, has developed a niche market for people wishing to build their barndominium. The use of metal panels is something that practically all barndominiums have in common.

Barndominiums are vast, open structures that allow simple customization. The residential quarters in these structures are frequently positioned on the second story. The first story functions as a barn, shophouse, storage room, and so on. Your living space may now serve more functions depending on your needs. Steel structure and sheet metal siding make the building easy to seal, making it energy-efficient.

Furthermore, most barndominiums include energy-efficient windows and spray foam insulation. Passive solar heating is frequently included in the construction of barndominiums. Allowing heat from the sun to enter the home through wide, energy-efficient windows and storing the heat in the thermal mass of concrete flooring is part of the design.

Due to the broad, open floor design of barndominiums, building the barndominium is typically completed on a shorter timeline. These objects are made of steel structure and metal siding for durability, as we already mentioned, which makes them extremely sturdy and resistant to the weather.

They are built to accommodate both working and residential spaces. As a result, they're an excellent choice for folks who want an adaptable home. Because of the open interiors, upgrades and alterations are simple.

Barndominiums are usually constructed as a shell with a basic inside framework. Because they are not complicated constructions, they require less time to complete.

If you are building a new barndominium or have never insulated your old one, here is what you should know about insulating these objects.

Metal structures retain heat well, which is ideal if you live in a chilly climate. In some locations, however, a metal barndominium without insulation may be really uncomfortable.

Metal is a poor insulator because it readily absorbs heat and cold. So in order to reach the same quality of insulation as pole barn insulation, for example, barndominium insulation needs to be more effective. During the hotter months, the sunlight reaches the metal sheeting and heats and humidifies the interior of the structure. As the temperature decreases, the metal sheeting turns cold, cooling the inside and usually causing condensation issues.

Insulation helps to keep the temperature steady by preventing air transfer. This allows you to have more control over the temperature within your barndominium.

Condensation may be avoided by adding barndominium insulation. Condensation happens when heated air from the sun or your heater collides with the cool metal covering. It may cause foundation damage or raise the danger of corrosion over time.

Insulation not only protects your home from temperature fluctuations and humidity, but it also acts as a sound barrier. When using insulation with added materials that help with acoustic isolation like acoustic wall insulation, exterior sounds, like the sound of automobiles or people passing by, can be muffled pretty well.

Without insulation, the temperature inside your barndominium may be comparable with the one outside. Heat may readily seep through the metal exterior and into your home when it heats up. As the temperature drops, the absence of insulation causes heat to escape.

Each form of insulation has a distinct amount of heat flow resistance. This resistance is referred to as the insulation's "R-value." By preventing heat transmission, a greater R-value enables better temperature control and energy efficiency.

The US Department of Energy advises using wall insulation for your barndominium with at least R13 for a residence with wood stud frames built with 24 studs. If the house contains 26 studs, the R-value should be at least R19.

Despite this, barndominiums are frequently constructed with steel frames rather than wood stud frames. In that case, you will have a deeper wall cavity, which allows you to add more insulation to the walls than is advised.

The Department of Energy recommends R30 to R60 insulation for attics in the Southeast, which encompasses Florida, Georgia, Louisiana, Texas, Oklahoma, Alabama, Mississippi, and Arkansas. For the rest of the country, an R-value of R49 to R60 is suggested for attics.

The following are the most frequent forms of insulation:

• Batt insulation
• Roll insulation
• Foam board insulation
• Radiant barriers
• Blown-in insulation
• Spray foam insulation

Many barndominium designs have a single level with an open ceiling, obviating the need for an attic. In that case, you probably shouldn’t install blown-in insulation or spray foam, given they are mostly used for attic insulation. It is also difficult to add batt or roll insulation without first completing the ceiling.

So you should consider utilizing foam board or radiation barriers if you intend to leave the ceiling exposed. Prodex total 5M and prodex total 5M plus are stiff panels that may be used in almost any place that has a flat surface. In addition to being utilized beneath the roof, foam boards are frequently employed as flooring as well.

Radiant barriers deflect heat away from your home but do not help greatly with heat retention. They function well in barndominium attics and roofs in southern states with mild winters.

While foam board and radiant barriers are the greatest options for insulating the top of the barndominium, you may use any of the other forms of insulation for the walls.

The cheapest solution for insulating the barndominium walls is batt and roll insulation like 24-inch Prodex Total 5M. They are also less expensive to install than blown-in or spray foam insulation but provide less coverage.

Blown-in and spray foam insulation have the greatest coverage and insulating value. But they, on the other hand, often require expert installation, which raises the expense.

Choosing the right insulation for your barndominium might be difficult. People like to create a barndominium since it is less expensive than a standard home. Opting for the best insulation for your situation can help increase the cost-efficiency of your barndominium.

The first step in insulating a metal building is selecting the appropriate insulation. Spray foam and blown-in insulation are the easiest to install if your home is already built

Blanket insulation and stiff boards are the simplest materials for new barndominium construction, especially if you are doing the work yourself.

Now, after you have picked the insulation material check the local construction codes as well. Some jurisdictions demand a minimum R-value for insulation. In some areas, an extra vapor barrier may be required.

Next, measure the distance between the wall studs while applying blanket insulation or rigid boards. Measure the distance between the joists in the attics and floors. To calculate the quantity of insulation needed for the project multiply the total measures by the height of the ceiling.

Check the pipes before installing the barndominium insulation. If pipes go into wall cavities or floors where insulation will be installed, foam pipe sleeves may be required to prevent condensation.

The following step is to fill any gaps between the fittings, joists, and studs. Caulk should be used around smaller gaps. When utilizing a do-it-yourself spray foam kit, you may omit this step.

Start with the attic and work your way down while installing barndominium insulation. The attic is likely to require the greatest work, such as installing foam wraps around plumbing or electrical cables.

Before putting the drywall, cut blanket insulation or stiff boards to fit between the wall cavities. When utilizing spray foam or blown-in insulation, follow the manufacturer's guidelines. While the specifics vary, spray foam and blown-in insulation often require access to the wall hollow after the walls have been built.
