Description

Double Bubble Insulation provides an effective way to manage heat and moisture in compact or enclosed areas. Its dual-bubble structure forms a built-in air pocket that slows the movement of hot and cold temperatures, helping maintain more consistent conditions in garages, sheds, doghouses, RVs, and vehicles. By reducing direct temperature transfer, the insulation also limits condensation buildup in changing weather. For optimal moisture control, all seams should be sealed with insulation tape to create a continuous vapor barrier.

Reliable Radiant Heat Reflection for Small Spaces

This insulation is designed to reflect radiant heat, making it a practical solution for structures that experience intense sun exposure or seasonal temperature swings. Its lightweight build fits easily into tight or irregular spaces where traditional insulation is difficult to install.

Easy-to-Install Double Bubble Insulation for Garages, RVs & More

The dual-bubble layer adds strength and flexibility, allowing the material to contour to various surfaces. It installs quickly with simple hand tools and delivers long-lasting performance once seams are properly sealed. Whether you're adding comfort to a workspace or protecting stored items from heat and moisture, this insulation delivers dependable results.

Key Features

  • Dual-bubble thermal break: Helps block heat transfer and stabilize interior temperatures.
  • Condensation reduction: Minimizes moisture buildup in fluctuating climates.
  • Flexible for tight spaces: Ideal for garages, sheds, doghouses, RVs, and vehicles.
  • Lightweight and easy to cut: Installs cleanly with basic tools.
  • Reflective heat control: Helps reduce radiant heat in warm conditions.
  • Vapor barrier when taped: Sealing seams enhances moisture protection.
  • Durable construction: Polyethylene bubble core withstands handling and long-term use.

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!.
