Metal Building Insulation Guide for Commercial Projects

Metal Buildings and Insulation

No matter where you call home, metal buildings are a prevalent choice for commercial businesses of all sizes and kinds. In fact, they’re used in over 80% of all new commercial construction projects! These structures are regularly utilized for retail storefronts, warehouses, manufacturing facilities, and more. They’re strong, cost-effective, and built to last for years with minimal maintenance needs.

However, without proper insulation, metal buildings can be susceptible to a range of issues, such as moisture buildup and uneven temperatures. Moisture buildup can promote oxidation and allow mold to form in your structure. But with the proper insulation, you can easily transform a metal building into one of the most energy-efficient building types on the market.

So, if you’re in the market for a commercial-grade metal building, you’ll want to keep reading! In this blog, we’ll cover everything you need to ensure your new building stays moisture-free.

Why Commercial Metal Buildings Need Insulation

While metal buildings are engineered to withstand the exterior elements, the inside of your structure is equally important. And if you plan to use your building commercially, having the right insulation is a must. Here’s why:

Creates a Moisture Barrier

One of the primary reasons for steel building insulation is to create a moisture barrier. Insulation helps to prevent moisture buildup by creating a barrier between the interior and exterior of the building. Without insulation, steel buildings can be prone to condensation buildup, leading to mold, mildew, and corrosion.

Regulates Internal Temperature

Another key benefit of steel building insulation is its ability to regulate the internal temperature of your structure. Metal is a good conductor of heat and cold, making maintaining a consistent temperature inside the building difficult. Insulation helps to regulate this temperature by reducing the transfer of heat and cold through the metal, keeping the interior of the building at a consistent temperature.

Absorbs Loud Sounds

Metal buildings can often be noisy, with sounds reverberating off the metal surfaces. Insulation helps to absorb sound and reduce the noise levels inside the building. This is particularly important for commercial and industrial buildings, where noise levels can affect the comfort of employees and customers.

Improves Resale Value

Steel building insulation can also help improve the resale value of the building. Insulation is valuable to any metal building, as it improves energy efficiency, reduces noise levels, and creates a moisture barrier. These factors can all contribute to a higher resale value when it comes time to sell the building.

Increases Energy Efficiency

Finally, steel building insulation can help increase the energy efficiency of the building. Insulation reduces the energy needed to maintain a comfortable temperature inside the building, leading to lower energy bills and reduced environmental impact. This is a vital consideration for those looking to reduce their carbon footprint and save on energy costs over time.

How to Insulate a Metal Building

When it comes to insulating your metal building, you’ll have several options to choose from. These insulation types will vary in terms of capability, so you’ll want to perform the necessary research to get the right type for your region. Below, we’ve illustrated the steps you’ll want to take to insulate your building the right way:

Choose Your Insulation Type

The first step in insulating a metal building is determining the type of insulation that is best for your needs. Common types of insulation include fiberglass batts, spray foam, and reflective insulation. Each type has its advantages and disadvantages, so it’s necessary to research and determine the best fit for your specific building and climate.

Measure Your Building

Before purchasing insulation, you’ll need to measure your metal building to determine how much insulation you’ll need. Measure the length, width, and height of the walls and roof to calculate the square footage of the building.

Hire a Professional

While it’s possible to install insulation yourself with metal building insulation kits, it’s recommended to hire a professional for the job. A professional can help ensure the insulation is installed correctly, minimizing the risk of moisture buildup or air leaks. Additionally, a professional can help determine the best type of insulation for your specific needs.

Insulate Your Walls

Once you have determined the type and amount of insulation needed, it’s time to install it. Start by insulating the walls, following the manufacturer’s instructions for the insulation type. Common methods include using adhesive, clips, or strapping to hold the insulation in place.

Insulate the Roof

After insulating the walls, it’s time to insulate the roof. Depending on the type of insulation being used, this may involve installing insulation panels or spraying foam onto the underside of the roof. Again, it’s critical to follow the manufacturer’s instructions for the specific insulation type.

Seal Any Air Leaks

You’ll also want to seal any air leaks in your building to prevent heat loss and moisture buildup. This may involve using caulk or sealant around windows and doors and around any penetrations in the roof or walls, such as vents or pipes.

Insulation Provided by Metal Garage Central

In addition to offering a wide range of metal buildings for any job or application, Metal Garage Central is proud to provide a distinct lineup of premium insulation options. These include:

Single-Bubble Insulation

This type of insulation features a single layer of polyethylene bubbles that provide a barrier against heat transfer. Single-bubble insulation is an affordable option that can provide moderate thermal protection.

Double-Bubble Insulation

Double-bubble insulation features two layers of polyethylene bubbles with a layer of reflective foil in between. This creates a higher insulation level than single-bubble insulation, making it ideal for areas with extreme temperature fluctuations.


Prodex is a reflective insulation with a closed-cell foam layer sandwiched between two layers of reflective foil. This creates an effective barrier against heat transfer, making it an excellent option for insulation in metal buildings.

Drip Stop

Drip stop is a unique insulation solution that provides thermal protection and prevents moisture buildup. It features a layer of felt-like insulation backed by a layer of polyester that is adhered to the interior of your walls and roofing, which absorbs and wicks away any condensation that may form on the inside of the building.
