What Type of Insulation is Best For a Metal Building?

Insulation can make a big difference in the comfort and resale value of your steel building. It slows the transfer of heat, reduces condensation and moisture buildup, and protects against mold and mildew.

But what kind of insulation is best for a metal building? This article will discuss several insulation options that are available to you.


Whether you use your steel building for an auto shop, manufacturing, metal hobby or storage purposes, you need insulation to keep the temperature inside the structure consistent with the outside environment. It also protects the contents of your building from moisture, which can lead to rust and mold.

Fiberglass is the most popular choice for metal building insulation. It is available in both unfaced and faced styles, both of which can be used in metal buildings. This type of insulation consists of fiberglass or mineral wool batts that are installed between the metal building's framing members. This insulation is relatively inexpensive, easy to install and offers good thermal resistance. It also provides a vapor barrier, which is important for cold climates.

The best type of insulation for a metal building depends on your specific geographical location and construction budget. In many cases, the right solution is a combination of insulation options. For example, double bubble foil excels in nearly every criteria: It repels moisture well, reflects up to 95% of radiant heat and can help prevent corrosion. It also does not compress easily, which allows it to retain its R-value for longer periods of time.

Spray foam insulation is another excellent option for insulating metal buildings. It is a liquid polymer, often polyurethane, that is sprayed and expands to fill the smallest spaces. This type of insulation is highly effective and can be sprayed in difficult to reach places, such as the corners of a metal building. Spray foam insulation is more expensive than fiberglass or rigid board, however, and it requires professional installation.

Another way to insulate a metal building is with prefabricated insulated panels. These are panels with an insulated core that are placed between the metal panels of a prefabricated steel building. This type of insulation is cost-efficient, fast to install and looks attractive in any application.

Regardless of the type of insulation you choose for your metal building, it is important to pay attention to R-value. The higher the R-value, the more efficient the insulation is. A high R-value will save you money on your energy bills and extend the life of your metal building's insulation.


When properly insulated, a metal building protects its inhabitants from the hot summer sun and cold winter weather. In addition, it conserves energy, reduces outside noise, and prevents condensation and mold growth that can affect indoor air quality. All of these benefits can add up to a higher property value and increased usability for the building owner.

A key factor in choosing the right type of insulation for a metal building is its R-value, which measures how effectively it blocks the flow of heat. The higher the R-value, the more effective the insulation. There are several options for R-value insulation in metal buildings, including fiberglass batts, blanket insulation, rigid boards, and closed-cell spray foam.

Fiberglass is the most commonly used type of metal building insulation because it offers a high R-value for a lower cost than other types. It is available as a blown-in (loose-fill) or batt material and can be easily fitted between the joists and studs in a metal building. Another option for insulation is cellulose, which uses up to 85% recycled materials and requires less energy to manufacture than other types of insulation.

Blanket insulation, also called R-value insulation or loose-fill insulation, is made up of a combination of flexible materials that are often fiberglass, but can be made of mineral wool, cotton, batting, plastic, and other natural or man-made fibers. It is usually the least expensive type of insulation and can be easily installed between joists and studs, even in irregularly-shaped spaces.

Rigid board insulation, which is available in prefabricated panels or as a liquid spray that is applied to the exterior of a building, can be an excellent choice for metal buildings because it provides good thermal resistance and can be quickly installed. However, the insulation manufacturer and the metal building supplier should be in close coordination when using this type of insulation in order to ensure that the proper thickness is used and that it does not void the warranty on the steel building.

Foam and cellular spray foam are two other insulation options that are effective in metal buildings because they can seal tightly and provide good R-value. Both are available in a variety of densities, which can be adjusted to meet the requirements of each individual project.


The cotton candy pink fiberglass batt insulation that you may be most familiar with is a great option for many metal buildings. This type of insulation is a popular choice among construction professionals due to its affordability, ease of installation, and quality performance. It also helps homeowners and businesses reduce energy consumption and stay comfortable all year round.

Essentially, this insulation is comprised of pre-cut pieces that resemble a blanket and come in varying thicknesses. It can be made from a variety of materials, including fiberglass or mineral wool and is available in a wide range of R-values, from R-19 to R-30. The higher the R-value, the greater the insulating power of the material.

When it comes to deciding what kind of insulation you should use in your home, the advice of an experienced and trusted contractor is always recommended. There are multiple factors that need to be taken into consideration, such as your building style, geographical location, and budget. In many cases, a combination of different insulation types is more effective than any single option on its own.

Rigid board insulation is another popular option for metal buildings because of its versatility. It’s a good choice for retrofit projects, sound control, and climate control, but isn’t the best solution for areas with tight or narrow corners that are difficult to fit traditional batt insulation into. Rigid board insulation is made of either polyisocyanurate (PIR) or expanded polystyrene (EPS). Both are excellent choices for insulating metal buildings, as they resist moisture and air infiltration and help prevent condensation.

In addition to its thermal resistance, foam insulation is a great choice for metal buildings because it provides a vapor barrier and helps minimize condensation, which can lead to corrosion and mold growth. It also reflects radiant heat, which can save you on energy costs.

Although spray foam insulation is more expensive than other options, it offers the best R-value and provides the most efficient vapor barrier. It can be applied to a steel structure quickly and easily with the assistance of a trained technician. It is available in open-cell or closed-cell varieties. Open-cell spray foam is less dense, spongier, and more affordable than closed-cell spray foam, but it lacks the moisture-resistant vapor retarder of the latter.

Spray Foam

Insulation is a crucial part of a metal building’s construction. Not only does it help keep your structure cool and warm, but it also seals off humidity, prevents pests from invading, and protects your belongings from the elements. It also helps to boost the resale value of your building, as well as make it easier and safer to use.

There are several different kinds of insulation, but what’s best for your metal carport, shed, garage, or barn will depend on your geographical location and budget. If moisture retention is a top priority, spray foam is the best option. But if energy efficiency is more of a concern, fiberglass or batt insulation will do the trick.

Loose-fill and batt insulation are both made of fibrous materials, like fiberglass or mineral wool. They’re usually found in older homes, and are a great solution for protecting your steel building from condensation while providing a higher R-value per inch than foam insulation. However, they aren’t ideal for cold climates.

Another common form of insulation is blanket insulation, which is a roll or sheet that’s filled in a space between the metal framing. It’s available in a variety of thicknesses, and is typically used to add an R-value between studs or girts of a frame. It can be installed quickly and easily, but doesn’t offer the same level of protection from condensation as other forms of insulation.

Foil bubble insulation is the best way to insulate a metal building, and it’s one of the methods that’s preferred by smart buyers and top metal structure builders. This method involves lining the inside of your wall with reflective foil to help reflect radiant heat while blocking moisture and preventing mold, mildew, and corrosion.

There are a few different options for this kind of insulation, including Thermasheath and Durasheath. The former is a polyiso foam core insulation with aluminum foil facers, while the latter is a polyiso foam core insulation bonded to 7/16" OSB for a nailable surface. Both options are highly durable and provide high R-values while also ensuring that your metal building won’t void its warranty.

Insulation can make a big difference in the comfort and resale value of your steel building.
