Description

EcoFoil Double Bubble Foil Insulation is engineered for use in pole barns, metal buildings, basements, crawl spaces, and storage areas that experience wider temperature swings. This insulation combines a reflective radiant barrier with two layers of polyethylene bubbles, forming an internal air gap that limits temperature transfer between surfaces. The double-bubble design helps reduce frost and condensation in cold climates, while the thin, lightweight construction (approximately 1/4" thick) installs quickly with basic tools.

Radiant Heat Control for Pole Barns & Metal Structures

Double Bubble Foil Insulation reflects 94% of radiant heat, helping maintain more stable indoor temperatures throughout the year. Radiant barriers function differently than traditional insulation—they reflect heat instead of absorbing it—making them an effective companion to fiberglass or spray foam when enhanced energy performance is needed. When installed with an air gap, the reflective qualities work year-round to reduce heat gain in summer and limit heat loss in winter.

Moisture Protection & Vapor Barrier Performance

When all seams and joints are sealed with reflective tape, the insulation forms a continuous vapor barrier that helps block moisture movement. This added protection is essential for preventing mold, corrosion, and material degradation in high-humidity or unconditioned spaces. Note that Double Bubble Foil Insulation is not intended for under-slab applications; for concrete or radiant floor systems, use EcoFoil Under Slab Insulation.

Key Features

  • Dual-bubble thermal core: Creates an air gap that reduces heat transfer and limits condensation.
  • 94% heat reflection: Radiant barrier surface improves temperature control in moderate and cold regions.
  • Acts as a vapor barrier: Seal seams to block moisture and protect building materials.
  • Thin and lightweight: Approximately 1/4" thick for fast handling and installation.
  • Versatile building use: Ideal for pole barns, metal buildings, basements, crawl spaces, and storage units.

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!.
