Description

Double Bubble Reflective Insulation provides an effective way to manage heat and moisture in compact or unconditioned spaces. Its dual-bubble core creates an insulating air chamber that slows temperature transfer and helps stop condensation caused by warm air meeting cold surfaces. This makes it a reliable choice for garage doors, sheds, RVs, vehicles, pet shelters, and other small structures that experience wide swings in temperature. For full vapor-barrier performance, simply seal all seams with insulation tape.

Radiant Heat Reflection for Small & Specialty Spaces

The reflective outer layer helps deflect radiant heat, improving comfort and reducing heat buildup in spaces exposed to direct sunlight. The flexible design fits easily against curved, angled, or irregular surfaces, making installation simple in areas where traditional insulation is difficult to use.

Durable, Easy-to-Install Double Bubble Insulation

Lightweight and clean to handle, this insulation cuts quickly and attaches with tape, staples, or adhesive. The dual-bubble construction adds strength and stability while maintaining a thin profile, making it well suited for DIY projects and quick upgrades.

Key Features

  • Dual-bubble thermal layer: Creates an insulating air chamber that reduces heat transfer.
  • Condensation control: Helps limit moisture buildup in varying temperatures.
  • Flexible for tight or irregular spaces: Ideal for garage doors, sheds, RVs, vehicles, and doghouses.
  • Radiant heat reflection: Reflective surface helps reduce solar heat gain.
  • Easy installation: Lightweight material cuts and attaches with common tools.
  • Vapor barrier when taped: Sealing seams improves moisture protection.
  • Durable bubble core: Offers structure and long-term performance without added bulk.

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!.
