Description

EcoFoil Double Bubble Foil Insulation is engineered for efficient temperature control and moisture protection in pole barns, metal buildings, basements, crawl spaces, and storage units. Its dual-bubble core creates a built-in thermal break that reduces heat transfer and helps prevent condensation in demanding climates. The white interior surface delivers a cleaner, more finished appearance wherever it’s installed.

Reliable Radiant Barrier and Vapor Protection

This double-bubble insulation reflects up to 94% of radiant heat, helping maintain stable interior temperatures year-round. When all seams are taped, the material also functions as a continuous vapor barrier—blocking moisture movement that can lead to mold, corrosion, and temperature loss. The thin, lightweight design installs easily with basic tools, making it a practical choice for both professionals and DIY applications.

Radiant Bubble Insulation for Buildings and Pole Barns

Unlike traditional insulation that absorbs heat, radiant bubble insulation reflects heat away from its surface—keeping heat inside during winter and reducing solar gain in summer. It pairs well with fiberglass or spray foam to boost overall efficiency, especially in structures exposed to wide temperature swings.

Key Features

  • Dual-bubble thermal break: Reduces heat transfer and limits condensation in unconditioned or partially conditioned buildings.
  • High reflectivity: Reflects 94% of radiant heat for improved year-round comfort.
  • Vapor-tight system: When seams are taped, it delivers continuous moisture control.
  • Clean white interior finish: Provides a brighter, more finished appearance inside workspaces.
  • Lightweight, easy installation: Cuts and attaches quickly without specialized equipment.
  • Versatile application: Ideal for pole barns, metal buildings, basements, crawl spaces, and storage areas.
  • Works with other insulation: Complements fiberglass or foam products for stronger overall performance.

Note: Not for use under concrete slabs. For slab or radiant floor applications, use EcoFoil Under Slab Insulation.

Great

Bought this to use as skirting for our RV for the winter weather and it’s gonna work great! It’s thick and easy to use. We purchased the tape that’s suggested to go with it and we’re not happy with that. It sticks to the eco foil great but doesn’t stick to other surfaces good. We ended up purchasing actual silver duct tape and it worked great.

Radiant heat barrier

Love the product, shipped quickly. Absolutely great customer service which is becoming a rarity these days. Insulation went down without problem, seam tape went down great. The 4 stars is because something should be done with silver face, when installed with sunshine you will get an immediate tan. Very very bright. I'm not an engineer but I would think something could be done, maybe not. Actually give it 4 and 3/4 stars.

Easy to work with

Everything about his insulation is good. It's easy to work with. Easy for beginners. No mess. Would buy the recommended tape to tape seams together. Easy to cut. Hope it actually works and insulates!.
