• Reflect radiant heat away from your metal building or pole barn

    Keep radiant heat out

    In warmer months, protect your metal building from the elements by reflecting radiant heat away from your building.

  • Prevent heat from escaping your metal building or pole barn

    Prevent heat from escaping

    In cooler months, maintain a more comfortable temperature by reflecting interior heat back in where it belongs.

  • Prevent condensation with Bubble Insulation

    Minimizes buildup of condensation

    When seams are taped, bubble insulation doubles as a vapor barrier, preventing buildup of frost and condensation on steel panels.

EcoFoil Bubble Insulation Radiant Barrier for Metal Buildings

Why use EcoFoil Bubble Insulation in your metal building or pole barn?

In short, you'll save money on utility bills and greatly reduce the chances of frost and condensation forming, which can lead to costly issues down the road. Metal siding/roofing conducts heat well, which means radiant heat transfers easily on both sides of your walls or roof. This creates a challenge when running a heater inside a metal building in the winter—interior heat passes through your walls and out of your building. When you install a radiant barrier on your walls and/or roof, you're reflecting the heat back to its source. This same effect works to your advantage in the warm summer months, reflecting the sun's rays away from your building.

See how it works

A radiant barrier and vapor barrier, all in one.

When you choose Single (warmer climates) or Double Bubble (colder climates) Insulation, you're adding extra protection against build-up of frost and condensation that often forms when temperature differences are extreme on either side of your walls or roof. And when properly sealed with tape, this product also forms a vapor barrier which further prevents passage of moisture.

Installing Bubble Insulation in a metal building or pole barn

Lightweight, durable, and installs easily

EcoFoil Bubble Insulation is a lightweight, durable, and safe product that is easy to install without any special clothing or breathing equipment required. EcoFoil Bubble Insulation can be installed quickly and easily in new and existing buildings—simply staple the product to exposed wall studs, and tape the seams to create a vapor barrier which locks out moisture. For optimal results, make sure there's an air space on at least one side of the material—it shouldn't be sandwiched tightly between two surfaces. If you live in a colder climate, choose Double Bubble which offers extra condensation protection. If you live in a warmer environment, Single Bubble will be enough since temperature differences between the interior/exterior of your building will be less extreme.

More About Metal Building Insulation

When insulating a metal building, a vapor barrier is an important factor. Since steel conducts heat well, a metal building naturally transfers heat energy in and out very freely. The moisture inside of an uninsulated building will easily form condensation on the inside of the steel panels when there is a significant temperature difference outside the building. Using EcoFoil Bubble Insulation resolves this problem by reflecting radiant heat to keep the temperature differential off of your buildings steel panels. All of our bubble insulations also have a perm rating of less than 1.0, which classifies them as a full vapor barrier. Being a vapor barrier prevents moisture from passing through our insulation and getting to the steel panels where it can turn into condensation.

There's a large variety of insulation options when it comes to metal buildings. The most common types of metal building insulation are radiant barrier, fiberglass insulation, rigid foam insulation and spray foam insulation. Fiberglass and other traditional insulations for metal buildings resist heat loss by conduction and convection but has little effect on radiant heat gain/loss. Radiant heat can account for up to 70% of a buildings overall heat gain or loss. This is why we recommend EcoFoil bubble insulation for most metal building applications. It's important to know that EcoFoil bubble insulation can absolutely be used in conjunction with other forms of traditional insulation for a combination to work against all 3 types of heat transfer. To get a more in depth explanation of heat transfer and how radiant barriers work, check out our How Does A Radiant Barrier Work page.

EcoFoil Bubble Insulation comes in different sized rolls and can be ordered with foil on both sides of it or foil on one side and white on the other. Both of these products will work in the exact same way. Many people choose to use the EcoFoil Double Bubble White Insulation if the product will be left exposed as it gives the metal building a nice clean, bright finish.

Why use EcoFoil in your metal building?

EcoFoil Bubble Insulation is the recommended product for use in metal buildings. It's designed to be installed in the walls and roof to help keep your building cooler in the summer and warmer in the winter.

Benefits of Bubble Insulation:

Great Transaction

Product is great! Packaging ruins 5ft per roll.

Product is accomplishing our goal is insulating our roll up doors but the packaging tape and label are not removable so the first 5 feet of product are ruined. We are extremely tight on our order quantity and sure could have used the 5'x4 rolls of material.... 20ft wasted

Thank you for taking the time to provide a review on this product! We are so sorry to hear about the issue with packaging. This has been submitted to our quality team for further evaluation and investigation into our shipping methods for this product. We appreciate your feedback into this as it helps us to improve!

Excellent product easy to work with and great price

Alice Lang

Love the stuff. We can feel a difference in temperature already! We are insulating our 40 x 40 garage/workshop/music room!! When we stand beside the wall without the double bubble it is warm. With the insulation installed you don't feel the heat radiating inward. We put the silver inside and the white side facing out. Finishes it more and it looks nice. We stapled it to wood furring we adhered (with Liquid Nails made for metal installations) to the inside of the metal building. We used the tape to put two pieces together to hold them. Good product!

Thank you for taking the time to provide a review on this product! We are so happy to hear that this made a difference in temperature in your garage! Customer feedback like yours helps us to continue to assess our products so that we can provide top quality products. Please reach out if we can be of any assistance in the future!
