If you’re thinking about adding a metal building to your property, it’s important to also consider the type of insulation you’re going to use.
Metal building insulation is critical if you’re looking to control moisture in the building, make it more energy efficient, and be able to enjoy it for years to come.
Having the right insulation can help to regulate the temperature in the building and save you money.
When looking at metal building insulation, it’s important to assess the R-value. This is how well the insulation resists heat traveling through it. The higher the R-value the better insulation you will have. To put this in perspective, an R-2 value is the bare minimum on the market and the average home has an R-34 insulation value.
The team at Value Metal Buildings has compiled this guide which explains how R-value affects insulation and provides everything you need to know about metal building insulation.

Why Metal Building Insulation Matters
One of the main reasons why having the right insulation installed in your metal building is important is because it helps to control condensation. Metal buildings can be prone to condensation because of their high thermal conductivity. Insulation helps to regulate temperature differences between the inside and outside of the building, controlling condensation. Since condensation can lead to rust and mold, controlling it is important to prevent this from happening.
When you have the proper metal building insulation, it also helps to minimize the transfer of heat which means your HVAC system won’t have to work so hard. This helps to maintain a comfortable temperature and lower energy bills.
As you determine which type of insulation is best for your metal building, you want to consider the R-value. The higher the R-value, the better the thermal resistance will be. This means your building will stay warmer in the winter and cooler in the summer by preventing heat from moving through your metal building. While you may be able to choose the type of insulation for your metal building, some insurance policies do require specific insulation for coverage, so it’s important to check your specific policy and follow these guidelines.
Best Types of Insulation for Metal Buildings
There are several different types of metal building insulation to consider. These include:
Fiberglass Insulation
Fiberglass insulation is most commonly used for metal buildings because it is easy to install and is cost-effective. This type of metal building insulation can also be easily adapted to fit the unique dimensions of different types of metal buildings. It also comes in different options, depending on your preferences. Fiberglass insulation is available in 2-inch (R-8) and 4-inch (R-16) options.
Spray Foam Insulation
While spray foam insulation can provide an airtight seal, it does require a moisture barrier on the roof to prevent rust from forming. If air pockets get damp, there can be serious rust issues over time. The R-value of spray foam insulation depends on the type of foam and product you choose.
Rigid Board Insulation
Rigid board insulation is a good consideration for walls and ceilings but is often used with moisture barriers. It is known to have a high R-value per inch. The exact R-value depends on the material, thickness, and number of layers of insulation.
Reflective or Radiant Barrier Insulation
People may choose reflective or radiant barrier insulation as their metal building insulation because it is ideal for reducing the heat that comes from sunlight. One interesting note about radiant barrier insulation is that it is not assigned an R-value on its own because its main job is to reflect radiant heat, not to resist conductive heat transfer. It is often used in combination with fiberglass insulation for maximum efficiency.
Moisture Barrier vs. Insulating Material
As you do your homework about metal building insulation, you may see a lot of discussion about moisture barriers. There is one key distinction between the moisture barriers and insulating material. Moisture barriers protect against condensation while insulation regulates temperature. It is always recommended to add a moisture barrier to the roof to prevent moisture buildup. Without it, condensation can occur which can lead to mold growth, water damage, metal corrosion, and other structural damage.
It is important to choose the right metal building insulation to preserve the lifespan of your investment. When looking at fiberglass insulation, the most popular type of metal building insulation, be aware that it is available in an R-8 or R-16 value, compared to the average home insulation of an R-34 rating. Always consult your insurance policy before selecting insulation materials to see if there are certain requirements.
How to Choose the Right Metal Building Insulation
If you are free to choose whatever type of metal building insulation you prefer, there are several factors to consider:
Frequently Asked Questions About Metal Building Insulation
What is the best insulation for metal buildings?
The best metal building insulation will depend on the climate, your budget, and what you intend to use the space for. Most people typically choose fiberglass insulation because it is cost-effective and easy to install.
Why is a moisture barrier necessary?
A moisture barrier is necessary because it prevents condensation that can lead to mold, mildew, and rust damage, all of which can be expensive to remedy.
How does R-value impact metal building insulation?
The higher the R-value, the better insulation the product will provide.
Can I use spray foam for insulation?
You can use spray foam for insulation, but only if a moisture barrier is also present on the roof to prevent rust.
Should I check with my insurance provider before choosing insulation?
Always check with your insurance carrier before choosing your insulation because it can impact your coverage. Some carriers require a specific type of insulation to be used.
